The UK has an outstanding history of timber architecture and with the huge growth of engineered timber components, including CLT and glulam, architects and structural engineers have created some of the best looking, sustainable, healthy and technically advanced buildings for generations. You can see many examples amongst the shortlisted projects for the Best Use of Timber Technology at the 2019 Offsite Awards – being held at Futurebuild – that show an immense depth of talent. Sponsored by the Structural Timber Association (STA) – the Best Use of Timber Technology category rewards the outstanding use of timber technology and innovators in the sector. Now in its fifth year, the Offsite Awards have grown in stature, attracting over 350 delegates and this year the winners will be announced on 5 March during Futurebuild. The Materials Hub also promises to be unmissable for timber professionals. Visitors will have the opportunity to view the work created as part of the TRADA University Challenge competition and will also host a CPD-accredited seminar programme to provide a wealth of knowledge for visitors. The Natural Building Area will also feature in the Materials Hub, providing free educational information and showcasing
natural materials and businesses that work in the UK natural building industry. Elsewhere in this issue we hear more about the continuing success of Södra Wood who have developed a solid reputation as a core supplier of timber components to all four corners of the construction sector – potentially this could also soon include CLT. Amongst some exceptional project case studies we offer the Boiler House, Cowan Court and Cranleigh Preparatory School, plus we hear more about why TV’s Grand Designs visited a SIPS factory. Of course, key to offsite delivery is the use of design for manufacture and assembly (DfMA) thinking. Sarah Newine Moore, Project Manager at Eurban, highlights several DfMA talking points with relation to the continuing development of the solid timber industry and how it makes projects more efficient and delivers greater quality and productivity. Many thanks to all our contributors, advertisers and supporters. See you at Futurebuild… Gary Ramsay | Consultant Editor E: firstname.lastname@example.org

COVER STORY – B&K STRUCTURES
Ethical and Sustainable Structural Solutions B&K Structures has delivered an innovative timber and steel structure for Cambridge Heath Road, a unique and forward-thinking commercial space that combines newbuild and existing elements to extraordinary effect. long-term collaborator Waugh Thistleton, main contractor ARJ Construction, and structural engineers Ramboll, with Veretec as the executive architects. This was a uniquely complex project, requiring the blending of the original concrete block with newbuild and extension elements, all of which relied on B&K Structures’ use of offsite technology to succeed. The company designed, supplied and installed a hybrid structure which blended structural steel, glulam and cross-laminated timber (CLT) to extend the full floorplate of the building to 50,000sq ft. Central to the design is a beautiful CLT-framed atrium which encourages co-working and a sense of community between the charities housed in the space.
01 A scheme described by architect Waugh Thistleton as ‘environmentally exemplary’, the Cambridge Heath Road scheme used pioneering construction methods to replace a derelict 1962 office block, with a modern workplace that will provide a flexible space to accommodate The Ethical Property Company’s 25 charity clients. Environmental concerns – in particular reducing the building’s carbon footprint – were central to The Ethical Property
Company’s brief. The remit also called for open communal spaces that would encourage the building’s eventual tenants to network and collaborate, and there was a strong emphasis on maximising the available space within the finished building. B&K Structures’ reputation for delivering innovative structural solutions, which put sustainability at the heart of the methodology, made the company the ideal choice to deliver this scheme in partnership with

B&K Structures is the leading sustainable and hybrid structural frame specialist in the UK, reating ground-breaking multi-award winning structures with outstanding green credentials for some of the UK’s largest construction companies. Working across some of the UK’s most forward-thinking construction projects, including residential developments, commercial buildings, and the public sector, B&K Structures improves build quality and building health as well as increasing the speed of construction and reducing environmental impact.
COVER STORY – B&K STRUCTURES
B&K Structures was able to deliver and install the steel, CLT and glulam elements within a two-phase programme of just 44 weeks and if supplied in one single phase, the project delivery would have been a lot shorter. Offsite construction methods helped to speed up the build process significantly when compared with a traditional construction programme for a project this size.
Ethical Property Company, says: “Ethical Property has had a great experience working with B&K Structures, Waugh Thistleton and ARJ Construction. The end result is a stunning building and a great place for our tenants to carry out their work to achieve social change.”
The B&K Structures’ approach delivers many benefits. The use of sustainably sourced timber and offsite manufacturing methods reduces the weight of superstructures, aids foundation designs, limits the number of people required for on-site operations and minimises the number of deliveries to site. And the use of CLT as a sustainable alternative to concrete drastically lowers the project’s carbon footprint. For any commercial project, cost, sustainability and return on investment are high on the agenda: that’s what makes a hybrid structure such an appealing solution for projects like Cambridge Heath Road.
What’s more, the use of lightweight steel in the structure allowed for open floor spaces, and large unsupported spans. This worked well as part of a hybrid solution, with steel and timber complementing each other to create a sustainable and economical alternative to 100% steel. In the case of Cambridge Heath Road, steel was blended with high-quality CLT panels and glulam to create expansive communal areas such as the central atrium. According to Waugh Thistleton, as well as providing a new dynamic frontage onto Cambridge Heath Road, the extension to the front of the building will facilitate the passive regulation of noise, heating, sunlight and ventilation. This in turn helps reduce the running costs for the building by decreasing the use of artificial light and heating. The impressive building is now fully operational and The Ethical Property Company’s clients have already taken up their space within the building. Commenting on the finished project, Nick Forster, Director of Special Projects at The
B&K Structures’ Head of Marketing, Wayne Yeomans, added: “Cambridge Heath Road encapsulates the benefits that a hybrid steel and timber structure, and offsite construction methods, can bring to commercial projects. We were able to create space, minimise the project’s carbon footprint, and deliver the finished structure within a tight time-frame to ensure that the building achieved everything the Ethical Property Company called for in the original brief. This is a truly impressive commercial building and is the perfect showcase for what can be achieved when sustainable construction is put at the top of the agenda.”

UK INDUSTRY NEWS ICONIC NEW LOOK FOR CENTRAL BANK OF IRELAND
WORTHY WINNERS AT BWF AWARDS The winners of the prestigious British Woodworking Federation (BWF) Awards 2018 were revealed last November at a glittering awards evening held at Stationer’s Hall in central London. Now in their tenth year, the BWF Awards celebrate the best in UK woodworking, recognising technical innovation, design, process efficiencies, health and safety and the rising stars of the industry.
Ireland’s most iconic new building, the Central Bank of Ireland is Ireland’s first ever BREEAM “Outstanding” rated building, setting an example of progressive construction that thinks about the future. Architects Henry J Lyons achieved this by designing the large sweeping interiors to be as user friendly as possible for the Bank’s staff, by specifying acoustic wood panels from Woodfit Acoustics, made from MEDITE PREMIER FR. This MDF panel from MEDITE SMARTPLY is flame retardant for safe use in public buildings and is produced using FSC-certified timber. The modern interior is conducive to teamwork and collaboration through use of natural light, safe, natural materials and acoustic performance. “The human experience was considered first and foremost in this project,” says Fergal Costello, Marketing Manager at Woodfit Acoustics. “Acoustics are extremely important in a big open building such as this one, to reduce reverberation while not restricting air circulation. It’s important to us and our clients that we are always environmentally responsible. We feel a strong responsibility to be able to meet
the need for acoustic panels made from sustainably produced materials. Working with MDF in particular, as it’s made from timber thinnings, ensures there is less timber wastage, and allows us in the timber industry to be a lot more efficient and environmentally friendly at the same time.” Colin Wheatley, Product Manager at MEDITE SMARTPLY explained: “With responsible management, timber is a 100% renewable natural resource. BREEAM encourages us to use timber responsibly, and to create environments that are safe and healthy for occupants, in a way that will contribute to the maintenance of the natural world. The Central Bank of Ireland building’s renovation is a stunning example of this, in its safety-conscious application of FR that happens to also be extremely beautiful.We have been a long-time customer of MEDITE SMARTPLY for the reason that their products are trustworthy and high quality. As MEDITE PREMIER FR was developed specifically for use in fire rated applications, it was a must for an extremely high specification project such as this one.” SOURCE: https://bit.ly/2SkDKVs

NO DEAL BREXIT ADVICE FOR TIMBER DEALERS
MULTIFACETED FLEXIBILITY FOR ALL TIMBER CONSTRUCTION COMPANIES
Timber importers and exporters are being asked to consider requirements for their businesses in the event of a no deal Brexit. Department for Environment, Food & Rural Affairs has offered advice on preparing for checks on timber as part of contingency planning. Me and my Hundegger! Never change a winning team!
In a no deal scenario, businesses importing timber and timber products from the European Union (EU) and European Economic Area (EEA) and placing it on the UK market will have to carry out checks (known as ‘due diligence’) from day one of EU Exit. These checks demonstrate they are importing legally harvested timber, helping to protect against illegal deforestation. Due diligence checks would involve: • • •
Gathering information on the timber, including its species, quantity, supplier, country of harvest and compliance with applicable legislation Assessing the risk of timber being illegal, applying set criteria in the regulations Obtaining additional information or taking further steps to verify legality (for example testing or assessment of the supply chain)
JOINERY MACHINE HUNDEGGER ROBOT-Drive
Businesses can either develop their own systems for these checks or use one provided by an approved monitoring organisation. This is what businesses currently have to do when they import timber from the rest of the world. There will be no changes to the current process for businesses importing from outside the EU, UK producers first placing on the market, and internal UK trade. As before, they will need to conduct checks to confirm their timber is legally harvested. The Office for Product Safety and Standards (OPSS) – the body responsible for enforcement – has been working with companies involved in the timber trade to keep them informed about what they will need to do in a no deal scenario and how to minimise impacts to their business. Guidance for timber traders on issues surrounding the EU exit is available at: https://bit.ly/2DLiteY
Compact dimensions and modular design – the ROBOT-Drive offers maximum flexibility and almost unlimited processing possibilities for bars and panels. With the ROBOT-Drive, a 6-axis unit performs all the necessary work steps on the part – and in a single run. The solution for all requirements including timber glue construction from 20 x 60 mm to 300 x 1300 mm. The ROBOT-Drive is the most recent addition to the range of Hundegger joinery machines.

UK INDUSTRY NEWS BRISTOL CITY COUNCIL ORDERS ZEDPODS
Projections for Bristol’s population show an increase of 103,100 people over the next 21 years – a much higher increase than in other English cities. Consequently, Bristol is aiming to be at the forefront of developing the template to solve the UK housing crisis. During its first Housing Festival in late 2018, the city was looking for quality innovative solutions “to test and deliver innovative and affordable housing solutions over the next five years.” Councillor Paul Smith, Bristol City Council’s Cabinet Member for Housing committed the council to investing in six rapid-build,
timber modular homes from Zed Pods to be put up on a site that would normally be seen as undeliverable in terms of conventional development and offered to people in housing crisis within six months, subject to planning.
ZEDPods was chosen as a partner for this trial due to their desire to address key worker and affordable housing issues as well as the company’s focus on zero carbon, sustainability and belief in quality homes for all.
ZEDPod starter homes offer a high-quality housing solution that can be erected within days and generate more energy than they use. Designed by RIBA award winning architect Bill Dunster, the zero-carbon ZEDPod is a prefabricated home with a difference, offering almost instant housing solutions without the land and site issues associated with conventional new build.
Dr Rehan Khodabuccus, Operations Director of ZED Pods said: “We relish the opportunity to showcase the benefits of ZEDPod living to councillors, Mayors, housing associations and the pubic at the Bristol Housing Festival. It’s great that we’re further engaged with Bristol City Council to deliver six ZEDPods to stop key workers, young people and the vulnerable from being excluded from the housing market. We’re delighted that Bristol is at the forefront of delivering innovative and affordable solutions over the next five years.”
It is the first solution to specifically address the lack of city centre building spaces with a design that takes advantage of existing hard standings. The six units will be assembled simply sitting on the ground or on raised steel decks.

UK INDUSTRY NEWS MAKE A FABRIC FIRST DATE
A series of nationwide forums designed to help housing and construction professionals improve home energy efficiency across the UK has secured support from regional low carbon champions. Dorset County Council’s Low Carbon Dorset initiative hosts the first Low Carbon Homes event in March 2019, followed by University of Brighton’s Clean Growth UK in April and Manchester City Council in November – each having their own low carbon agenda. Low Carbon Homes is a UK-wide initiative which brings together leading experts to share best practice and pioneering methodologies to help clarify the route towards a low carbon future. LCH Forums are free-to-attend events open to everyone across the industry, including engineers, local authorities and housing professionals as well as landlords, developers and contractors. Delegates will have a choice of workshops which will include case studies and success stories as part of a tailored programme created with the guidance of host organisations to meet regional needs. The 2019 event programmes will each be produced with support from The Green Register, with emphasis on the proven Fabric First approach. Lucy Pedler and Dan Weisselberg will chair proceedings, foster discussion and host a workshop, whilst being the “critical friend” throughout the programme development process for each Forum.
“Low Carbon Homes is an important initiative which we’re delighted to be part of, as a collaborative approach is vital to drive towards low carbon living. The unique platform provided by Low Carbon Homes can facilitate meaningful and practical understanding between those directly involved in many areas of the housing sector”, says Lucy Pedler, The Green Register’s founder. Graham Lock, founder of Low Carbon Homes says “As reiterated during the recent Green GB Week, if the UK is to achieve its global obligations, there must be a rapid take-up in domestic energy efficiency – especially in the 80% of existing housing stock which is poor performing. For those working within the housing industry, the subject of energy efficiency has never been so important and we must all play a role in driving forward change.” Looking forward to the Manchester event in November 2019 Jon Sawyer, Director of Housing and Residential Growth, Manchester City Council, said: We're delighted to be able to host Low Carbon Homes in Manchester as we recognise the challenge of updating our existing housing stock to meet our Low Carbon targets and reduce fuel poverty. It's an important initiative of which we are proud to support.” The events are free to attend and more information can be found at: www.lowcarbonhomes.uk

GOVERNMENT PLEDGES TO PRIORITISE TIMBER INDUSTRY POST-BREXIT After a Westminster Hall debate on Leaving the EU, Environment Minister David Rutley MP committed to ‘strengthening the timber trade’ during a parliamentary debate on the implications of Brexit on the timber industry. Describing the industry as a ‘real priority’ for Government, the Minister also pledged to make sure that timber importers face as ‘few additional costs as possible’ after Brexit. The comments came after Martin Whitfield MP, the Chair of the All-Party Parliamentary Group for the Timber Industries, urged the Government to ensure that after we leave the EU, timber imports can continue clear customs the same way they do now. Martin Whitfield MP said: “Without frictionless trade, I believe we face a clear challenge to build the number of homes the Prime Minister has committed to providing over this parliament. This challenge exists because the supply of timber is essential to meeting housing demands. This sector, which contributes £10 billion to the UK economy each year is still hugely reliant on trade with EU countries. Incredibly, 90% of the timber used to build homes in the UK is imported from across Europe.” David Hopkins, Director of the Confederation of the Timber Industries (CTI) and Managing Director of the Timber Trade Federation (TTF) added: “We welcome the Minister’s commitment to minimise the additional costs of Brexit on the import and export of timber. I am glad that the Government understands the indispensable role our industry plays in the UK construction sector and the wider economy.” SOURCE: www.cti-timber.org

UK INDUSTRY NEWS WIRRAL WATERS MOVES AHEAD
Two of the North West’s biggest and most innovative developers, Peel Land and Property (Peel L&P) and Urban Splash, have agreed a joint venture to bring modular urban living to Wirral Waters, the UK’s largest regeneration project by consented floorspace. Contracts have now been exchanged on the £55 million development, which will be the first ever collaboration between Peel L&P and Urban Splash. The waterside residential quarter at Wirral Waters will incorporate 347 modular homes. The quarter will introduce four new and exciting housing products to the Wirral including – House, Mansion House, Villa and Fab House – with each property customised by purchasers before being created offsite in the Urban Splash modular factory and then delivered to site. Richard Mawdsley, Director of Development at Peel L&P, said: “Our new joint venture with Urban Splash is fantastic news for our
local community bringing the very latest in housing design and innovation to the site. This development, which follows hot on the heels of our announcement last month about a £90 million residential scheme comprising of 500 high-quality homes along Northbank, will transform the site into an internationally recognised destination with a residential quarter that will take the pressure off local greenbelts and help to tackle the current UK housing crisis. We’re now just waiting on the final piece of the jigsaw, securing a Housing Infrastructure Fund grant from Homes England. Only then can we finally get the first wave of housing underway at Wirral Waters.” The development will bring Urban Splash’s modular concept of factory-built homes to Merseyside for the first time. The company has other sites in Birmingham – where homes are currently on sale – Manchester, Salford and North Shields - where 10 of the homes have been designed by TV architect George Clarke. A fifth site is planned at New

UK INDUSTRY NEWS ACCOYA ® GLULAM FOR IVY COLLECTION RESTAURANT
The Ivy Collection, a select group of upmarket restaurants, brasseries and cafes, has recently opened its latest restaurant – The Ivy in the Park, in Canada Square Park, London. The creative design was able to successfully combine quality with sustainability with the specification of world-leading, high-performance sustainable wood, Accoya® throughout the striking newbuild. The new brasserie, opened to the public in October 2018, was designed by William Matthews Associates and, following a rigorous bid process, lead construction firm Wiehag were selected to build the latest eatery in the Ivy Collections’ portfolio. The new restaurant, with a two-level bar, restaurant and external dining area, is positioned within one of Canary Wharf’s most sustainable areas, overlooking a vibrant green space for events. The Ivy in the Park is constructed from glulam and CLT with internal members made from spruce, whilst external beams and columns are glulam Accoya®. The specification of Accoya® wood further extended to the rainscreen trellis which covers the external walls. For the Accoya®
wood elements of the project, a total of 47 glulam beams, 42 glulam columns and 740m² of rainscreen trellis were required. Wiehag machined it into the glulam beams and columns – alongside the trellis – and finished in the factory with a Remmers Aqua HSL 35 Grey Stain prior to installing onsite. Canary Wharf Group, who has overseen the largest urban regeneration project ever undertaken in Europe, wanted timber to be used for the external façade of this project, however they needed a low maintenance solution. Naturally, Accoya® wood was the ideal choice. The result is a building that juxtaposes itself from the cold metal and glass of Canary Wharf and offers a warm, wooden home to one of the most respected restaurant institutions in London. Accoya® wood is produced using Accsys’ proprietary acetylation process, which chemically alters the cell structure of the wood to resist distortion. Certified Cradle to Cradle™ (C2C) Gold in recognition of its sustainability credentials, Accoya® wood has the added benefit of offering peace of mind for the environmentally conscious.

HARDWOOD TIMBER HEADING UPWARDS
Grown in Britain has updated its price/size curve data for several different hardwood tree species commonly grown and sold in the UK. Grown in Britain encourages woodland owners to look closely at their woods and see what might be ready to thin or fell and take advantage of the growing demand for homegrown timber and boost the health of the woodland at the same time. This information has been updated to account for increases in value across the board in 2018. Overall markets have picked up this year – some markedly, others more modestly. Oak is in strong demand due to several reasons including the weak pound weaker import availability and China buying up French oak. Chairman of the Forestry Commission, Sir Harry Studholme said: “The rising prices of hardwood timber are fantastic news for woodland owners. Higher prices justify and encourage woodland management, and this management supports future production of this beautiful raw material. More than this, well-managed woodlands help plants and wildlife to flourish and store carbon to help tackle climate change. Grown in Britain are doing an exceptional job to develop the market for hardwood timber and realise these benefits.” Demand all around is on the rise with the supply of British timber increasing. By continuing to encourage woodland owners to relook at their woodlands and forests to see the value of the timber they are growing, this will continue to drive up the supply and demand for British hardwood timber.

UK INDUSTRY NEWS STEWART MILNE AND BARRATT CONTINUE OFFSITE DRIVE
WINTER 2018 TIMBER PRICES STABILISING Property Consultants Bidwells have released their Winter 2018 Timber Price Database which looks at the standing conifer timber prices achieved six months to December 2018, indicating prices in the timber market has stabilised following major increases over the previous half year. Returns from the sale of 776,970 cubic metres of private sector coniferous timber grown in Scotland, Northern England and a small amount in Wales with a total standing value to the grower of £29.8 million suggest that the meteoric rise in timber prices experienced in the half year between October 2017 and March 2018 has levelled off.
Stewart Milne Timber Systems (SMTS) is continuing to share specialist knowledge and industry expertise through a strategic and collaborative partnership with housebuilder Barratt Developments. The two companies have partnered to help address the UK housing crisis by adopting offsite manufacturing methods to build a sustainable marketplace. A shortage of supply to meet increased demand for housing has meant that the average UK home is now eight times higher than the average salary. Combating the rising problem, and to government meet targets to provide high quality homes at speed and pace, solutions such as offsite timber frame construction are increasingly being adopted by housebuilders. With Barratt partnering with SMTS for its timber frames, both are committed to developing offsite construction projects as part of their housing portfolio. Steered by a goal to achieve 20% of its total build per annum as offsite construction by 2020, Barratt has built nearly 3,000 timber frame homes over the last two years. Oliver Novakovic, Technical and Innovation Director at Barratt Developments, said: “We recognise that the supply chain holds an immense amount of knowledge about their
processes, materials and technologies and the key for us is to tap into that knowledge. We know housebuilding and understand the demands of our customer base and what they like. We also intimately understand the performance specifications that are required from new technologies. “SMTS has been a key partner of Barratt Developments over the last four years. This partnership has facilitated a significant increase in the group’s output of timber frame construction and engagement at all levels, from group directors to site teams, which has helped improve our understanding of timber frames.” John Smith, Head of Product and Innovation at SMTS added: “With heightened interest in offsite technology across the UK and beyond, this is a hugely exciting time for the housing industry. We are proud of every single project that we deliver alongside Barratt, producing exceptional results, using timber frames. Having established a collaborative and open relationship with Barratt, both adding a great deal of expertise and knowledge, this prestigious award cements the fantastic work we are collectively delivering as part of our shared framework.”
Continued weakness of sterling remains a major factor in UK grown timber prices, but high global demand and tightness of supply suggests no reason why the big picture will change in the foreseeable future. Raymond Henderson, Forestry Partner at Bidwells commented: “It is always difficult to predict the future, given the influence which global demand and exchange rates have on domestic timber values, but the overall macro-economic situation of increasing demand and tightening supplies suggests no reason to suspect a weakening of prices over the short term. We do of course live in strange times where informed projections are apt to be overtaken by events and the ongoing uncertainties created by the unfolding drama of the UK’s withdrawal from the EU – or possibly not as the case may be – make crystal ball gazing murkier and less certain than ever. That said, the fundamentals of timber sales should not alter too drastically regardless of our membership of the European club.” Reports are produced on a sixth monthly basis and new contributors are welcome. All information is treated in the strictest confidence.

Pursuing CLT Construction Recent announcements on legislation regarding banning the use of combustible materials in the external walls of high-rise residential buildings has grabbed many headlines. Anthony Thistleton, co-founder of leading architects Waugh Thistleton, outlines why this should not impede the success of structural timber including CLT.
01 A quiet revolution has been going on in building in the UK over the last few years that has the capacity to transform the delivery of new housing, offering high quality, healthy homes delivered rapidly and without costing the earth. The use of cross laminated timber (CLT) typically shaves around a third off the time to construct a housing development, working with wood is safer and quieter with less dust and other pollutants. It also needs far fewer deliveries â€“ around 15% of those required for a concrete frame. For the end user, the accuracy of a CLT frame results in airtight homes with the
timber walls adding to the insulation, leading to warm and comfortable homes. In fact, many CLT homes are performing at close to Passivhaus standards requiring minimal additional heating in even the coldest months. The UK has lead the world in the adoption of this technology, especially for mid-rise housing. At the end of last year, however, the government introduced legislation in response to the Grenfell Tower fire which could have unforeseen consequences on the growth of CLT in the UK and our global leadership in innovation. The legislation prevents the use of any combustible
28 | www.structuraltimbermagazine.co.uk | STMAG
material within the entire external wall of any residential building above 18 metres in height. The result of this is that CLT can no longer be used in external walls of these buildings. While the inclusion of CLT in the ban is not merited, it is not a ban on CLT itself and we are working hard with the industry to ensure that this message is understood. The impact of the legislation can be overstated â€“ in most CLT apartment blocks the majority of the heavy lifting is carried out in the core, internal walls and the floor slabs. Constructing these elements from CLT is complaint, as well as safe. The external
SOLID TIMBER All building materials have vulnerability to fire – even concrete – and it is incumbent on professionals to understand these and design their buildings to protect the occupants and ensure their safety. We are confident in the fire safety of CLT construction, however the industry needs to support more research and testing to demonstrate this unequivocally.
walls can be built from non-combustible materials, such as a metal framed system. The challenge for the industry therefore is to develop prefabricated wall panels that can be delivered to site concurrently with the CLT structural frame and minimise any impact on sequencing. There are already examples of this model of engineered timber construction is already, such as Brock Commons Tallwood House, an 18-storey student housing scheme in Vancouver, which was completed last year. The building is a CLT hybrid structure with floors of CLT supported on a frame of glulam columns and beams. The external walls are a lightweight closed panel metal frame system and the building would be completely compliant with the new UK legislation. In the USA, which is currently updating their building code to allow timber buildings up to 18 storeys, the principal models are a similar ‘post and beam’ construction. This change is supported by extensive fire testing.
We continue to press the case for better legislation that deals with the actual risks that were exposed at Grenfell and the dysfunction within the industry that allowed it to happen. Issues such as competence and responsibility that were raised in the Hackitt Report have yet to be addressed. We are hopeful that in the long term, legislation based on evidence rather than politics, will prevail. It is essential that we continue to push for the wider use of CLT in construction. In addition to the benefits in construction and use, using CLT creates long term storage
for CO2 sequestered during tree growth. Traditional building materials involve high levels of energy in their manufacture creating a significant carbon footprint – an average UK home has around 21 tonnes of embodied CO2 in the building fabric. In contrast, the figure for a CLT-built home is -19 tonnes CO2 - a saving of 40 tonnes. The UK needs to build 250,000 homes a year. Building these from CLT could create a saving of over 10 million tonnes of CO2 every year – the equivalent of taking two million cars off the road. Furthermore, widespread use of CLT can increase global demand for timber and drive reforestation, which is one of the only ways in which we can hope to meet the climate challenge.

Offsite Solutions – the answer to Brexit? As politicians wrestle with Brexit, demand is ramping up in the construction industry, particularly in the housing sector. To avoid any disturbance to this momentum – the STA as a leading industry body – must ensure that the best interests of its members and their customers are a key priority.
01 The NHBC has publicly declared that builders will struggle to meet the government’s target of delivering 300,000 homes a year in England by the mid-2020s, unless the industry switches to offsite construction technology. This is further reinforced by the statements made by the housebuilding industry regarding their ability to meet this target due to the skills shortage, with a reported 2,500 bricklayers needed for every extra 10,000 homes. If we consider that the UK needs to go from 220,000 to 300,000 units per annum, that’s a lot of brickies. Overlay this with the Brexit situation and the potential for an exodus of European construction workers, then we have more of a challenge to deliver on the government’s target for housing provision. So, the challenges are clear but we do not have to ‘reinvent’ the solution.

drive can provide a degree more certainty by offering accurate forecasting and the commitment that is needed in order to provide confidence to Barratt Developments and other housebuilders.
The security of supply chains has been at the forefront of many of the Brexit debates, in common with all major housebuilders, this is something that Barratt Developments’ has prioritised. It states that about 90% of its construction materials are manufactured or assembled in the UK, with pricing for almost all of these materials fixed until the end of June, with pricing for 40% fixed until December. Barratt said they had worked with suppliers to ensure that they were holding additional inventories of imported construction materials and that they had reviewed logistic routes to mitigate any potential border disruption caused by Brexit. From a supply chain perspective this
In order to deliver an increased volume of houses to meet market demand, Barratt Developments initiated a review to find the best offsite methods of construction. The review found that timber frame was the preferred option and so consulted STA member company, Stewart Milne Timber Systems (SMTS) to work with them to achieve their goal of producing more costeffective quality homes.

In an attempt to deliver 20% of their housing portfolio using offsite construction, Barratt Developments has already built more than 3,000 timber frame homes over the past two years through the collaboration.
STRUCTURAL TIMBER ASSOCIATION The structural timber sector has the capacity to deliver advanced timber systems in greater volume than any other offsite technology solution, a fact that is recognised by many volume housebuilders who appreciate all the benefits of this proven technology. Another of Britain's biggest housebuilding companies, Persimmon – is investing heavily in prefabricated housing. The York-based housebuilder acquired the Space4 timber frame factory at Castle Bromwich, near Birmingham, as part of its takeover of a smaller rival, Westbury in 2006. The factory sold more than 3,250 timber-frame home kits last year, a 19% rise on the previous year, supplying just over a third of Persimmon's homes. Speaking at the launch of the NHBC’s review for 2018, Steve Wood, Chief Executive said: “Unless modern methods of construction are taken up to a greater degree it will be very difficult to hit the 300,000 annual government housing targets.” This view was
supported by the NHBC’s Chief Operating Officer Neil Jefferson adding: “The industry is facing capacity problems that only new techniques can fix.” He cited Japan, where the bulk of homes are built in factories and traditional techniques are used to top that up to meet cyclical changes in demand.
The STA has formed a close partnership with Swedish Wood. As the largest timber trading partner and an EU member state, Sweden’s view on future trading relations is important. Tony Traynor, UK Project Manager for Swedish Wood said: “The Swedish Forest Industry recognises the UK as its most important export market for timber and timber products. The construction sector and in particular, the offsite manufactured timber technology developed by STA members, is important, as we feel that structural timber systems represent a great opportunity to assist the UK government in achieving its targets for both social and private housebuilding. With consistent product
production available from Swedish Wood members, we know they can maintain the timber volumes which would be needed for such an increase in housebuilding demand. Our member companies supplying into the various trade sectors in the UK remain optimistic that trade and the supply lines will be uninterrupted post Brexit.” For more information and to discuss STA membership visit: www.structuraltimber.co.uk

The Future is Made of Trees With over 51,000 members, Södra is Sweden’s largest forest-owner association with a business built on ‘value-generating’ relationships. There are exciting times ahead with the organisation gearing up to supply new products in 2019 and further expansion into the UK and European markets. new segment, where we will be offering the most cost-effective construction material in the market for high-rise buildings.” CLT and glulam in particular are exciting structural alternatives to steel, concrete and masonry. The new facility at Värö has been in development for just over a year and is now beginning to roll out its first panels on a trial basis.
01 Since its transition in 2017 from Crown Timber, Södra Wood has positioned itself as a pivotal player in the UK, as a marketleading distributor of structural timber products to the construction and merchant sectors. Central to this has been the longstanding ‘just in time’ delivery model with engineered wood an increasingly crucial element. The Södra range is set to be supplemented even further with the potential of cross laminated timber (CLT) entering the marketplace later this year. The company has built its first CLT facility at Värö – co-located with Södra’s pulp mill and sawmill – and is part of a wider
programme of investment and growth across the company’s diverse portfolio. For example, from 1 March, the annual production volume of sawn timber at the Mönsterås sawmill will increase by 100,000 m³. “The journey of change undertaken by Södra’s sawmills in recent years is now yielding results in terms of more competitive production and a better offering to our customers,” says Jörgen Lindquist, President of the Södra Wood business area. “We have identified CLT as an interesting product and believe that taking this next step in the value chain is a natural progression. CLT will provide the basis for a

“We have built a new CLT facility and installed all the necessary CNC machinery,” says Jeremy English, Great Britain and Ireland Sales Director, Manufacturing. “We are processing panels and testing our skills and ability to handle the product. We expect to be able to deliver CLT products in late 2019 from the factory we have just built, and we have plans for a second factory on a larger scale. It’s a big investment in people and skills to develop the business going forward.” Plans are initially to service the domestic and Scandinavian markets to the tune of 20,000m3 a year and rising to 100,000 quickly, so the targets are ambitious and have exciting implications for global markets. Brexit casts a shadow over everything of course and Södra are well prepared for whatever outcome of final negotiations – deal or no-deal. “Södra is making sure we have sufficient stock on the ground as of March 29 so we can continue supply easily,” adds Jeremy. “The only problems we foresee are bureaucratic ones. We have set up a separate company in Ireland – Södra Ireland Ltd – to make sure we can
SÖDRA work smoothly and is a prevention against potential bureaucracy. In a way you can’t plan – you can just look at options. But it should be business as normal.” As part of the fresh face of Södra for 2019, a brand new website was launched in January to serve as a ‘go-to source’ of information for those interested in specifying and working with timber. “The UK is one of our largest markets,” says Nigel Buckley-Ryan, UK Sales Director, Merchants at Södra. “So it is really important to have a UK-focused website that provides in-depth information about our products, and our commitment to growing a sustainable timber supply. It’s also a significant step forward in Södra’s commitment to be the industry’s most digitally-focused company.” 2019 will see the continued growth of Södra’s three main UK core ranges: C24 timber for carcassing, TR26 for trussed rafters, and CLS for the timber frame and merchant markets. “TR26 will be dictated to by increased housing starts and newbuild,” adds Jeremy. “CLS will grow due to the timber frame sector growing and C24 is always steady and increasingly linked to the RMI sector. Looking forward, as homegrown timber availability reaches a peak, the market will have to turn to imported timber. Södra has a long-term strategy to grow in three main markets – UK & Ireland, Sweden and Holland. Timber has been described as a ‘miracle’ building material – and for us there is no doubt that it can overcome many of today’s construction challenges, from helping to meet government housing targets to increasing speed and agility of construction dramatically.”
Värö is Södra’s key sawmill consuming around 1.2 million m3 of logs per year, 15% pine and 85% spruce to fuel a booming European market.
Finished products from Värö are mostly shipped from Varberg to international ports including Wicklow where Södra Ireland is best placed to deal with Brexit fallout.

Natural insulation: enhancing the health of a building and its occupants Alex Campbell, Director at Steico, explores the effects of making better decisions when it comes to choosing materials for your building on a building’s performance and occupant health.
01 Most of us spend the majority of our lives indoors. Little surprise then that the health of the buildings we live and work in, heavily influences our physical, psychological and social well-being. A healthy building is both life-enhancing and supports occupants’ health, mood and productivity. British buildings are currently regulated regards their ventilation and heating but there are some glaring omissions. For instance, indoor air quality and exposure to natural light remain free of legal requirements despite the health benefits they offer occupants. It’s the responsibility of the entire UK construction industry – from designers, to architects, to builders – to drive the need to change.
But how do we build healthy buildings when we’re already struggling with volume? The key to building healthy buildings is using natural materials which is no longer the more expensive solution. Natural building materials contribute to a healthier internal environment of a building – maintaining a more stable and comfortable temperature and humidity throughout the seasons as well as improving indoor air quality and acoustic properties. Although some of the more common building materials have their advantages, there is a better, more efficient way to build – and we hope this will soon become the norm. Insulation is a key component in a building’s design. There is a proven
34 | www.structuraltimbermagazine.co.uk | STMAG
relationship between insulation and the overall performance of a building and the health of its occupants. Natural insulation is hygroscopic in that it provides a degree of humidity control to a building, positively impacting its thermal comfort. It is typically recognised for its ability to retain heat within a building but it has an equally important role in preventing a building from overheating in summer months. The properties of natural insulation – such as woodfibre, sheep’s wool or cellulose – mean they tend to have a higher thermal mass than their synthetic alternatives, providing improved thermal efficiency.
02 Woodfibre insulation boards are quick and easy to install and thanks to their tongue and groove profile, the boards slot together seamlessly, creating a tight thermal envelope. The cleanliness of wood fibre insulation means it does not release any harmful chemicals as it degrades so carries zero risk of toxic emissions, dust or fibres. Natural insulation is also breathable and vapour-permeable – an essential quality to prevent the build-up of damp, condensation or structural decay. This is the key factor
in improving the overall indoor air quality. The higher density of natural materials also makes them more effective at mitigating noise pollution – both into and from a building – improving the occupants’ daily life. In years to come, our children’s children will wonder why on earth we continued putting synthetic insulation into buildings in 21st century – using up the world’s precious and dwindling non-sustainable resources

Woodfibre and CLT Woodfibre insulation specialist, NBT, has provided the company’s Pavatex insulation and airtightness membrane for a groundbreaking Taylor Wimpey residential scheme trialling cross laminated timber (CLT) and sustainable design. combination of woodfibre insulation and membrane for the project, and, alongside technical specification, the company has also provided training at its own facility and on site, installation guidance and fixings calculations to support the Taylor Wimpey team as the housebuilder pioneers CLT homes as part of a major scheme for the first time. “Timber construction and CLT are growing in popularity amongst many smaller developers,” says NBT’s Andrew Mitchell. “Because CLT is an extremely robust and lightweight material that offers excellent design flexibility. All timber products provide carbon lock up, actively offsetting carbon emissions from both the construction and occupation phase of the development, making them extremely environmentallyfriendly while ensuring an extended design life and comfortable indoor environment.
01 Taylor Wimpey’s is one of the housebuilders involved in developing Great Western Park in Didcot, Oxfordshire – an ambitious project to create a new community, including 3,300 new homes, along with schools, infrastructure improvements and public realm spaces. Taylor Wimpey, is utilising the development to construct concept homes using various alternatives to block and brick. The homes are part of Taylor Wimpey’s ‘Project 2020’ initiative, which aims to trial innovative prototypes that could be constructed on a grander
scale at future developments, as part of the company’s strategy for sustainable housebuilding. NBT’s Pavatex woodfibre insulation and DSB weatherproof membrane have been used on semi-detached and detached prototype CLT (cross-laminated timber) homes at Great Western Park as part of Taylor Wimpey’s Infinity development, which will be available for purchase alongside the conventionally-built houses. NBT advised on specification of the right

“Our products have been proven on a number of CLT builds but this is the firsttime we have worked with a major player in the housebuilding sector. We are excited to see that Taylor Wimpey is taking such a progressive approach to considering how they can build the homes of the future with reduced impact for the environment and enhanced comfort for residents.” A capillary-active, hygroscopic woodfibre insulation with excellent thermal performance, Pavatex was specified because, unlike closed cell and synthetic materials, it is a breathable insulation that allows any moisture absorbed by the structure during construction to dry to the outside, sharing the moisture load of the
INSULATION CLT and ensuring the longevity and integrity of the building fabric. The insulation was used to form a wrap around the external face of the building envelope and the structure was then wrapped with the Pavatex DSB membrane, which was pulled tight and the system was then fixed in place through batons prior to installation of the external wall finishes, which include brick slips, Cedral cladding and render. Danielle Heard, Sales and Marketing Director at Taylor Wimpey Oxfordshire said: “As a responsible and forward-focused housebuilder we have implemented our Project 2020 initiative to consider the materials we will use in the future to drive down carbon emissions, enhance the comfort and service life of the homes we build and ensure continuity of supply for the materials we use. “CLT and woodfibre are both renewable materials which offers significant benefits for the housebuilding sector in terms of both availability and sustainability. Woodfibre insulation not only provides excellent thermal performance during the winter but, thanks to its increased thermal mass, also protects against heat in summer, offering an ideal solution for homes that are comfortable all year round. Our Project 2020 trials are in their infancy at the moment but it’s inspiring to see what can be achieved with non-standard design and specification.” Taylor Wimpey’s Project 2020 aims to explore and evaluate trends, changes and new innovations in design, architecture, technology, materials and build methodology. The competition to find a new design for Taylor Wimpey houses was won by London-based Openstudio Architects with its Infinite House – a set of terrace housing prototypes. The Infinite House can be constructed from both traditional and offsite methods. CLT is likely to become more feasible over time as offsite construction becomes economically
02 viable, the architects says, but SIPS, timber framed or brick and block construction are also possible. Roof pitches have been optimised for PV panels and eaves spaces can be used for plant and M&E technology requirements.

Growth Expected in Woodfibre Insulation Woodfibre insulation currently accounts for less than 1% of the UK insulation market but supply problems in the mineral wool segment of the insulation market, coupled with fire risk concerns for poly-iso insulation products, has encouraged specifiers to re-examine how they are insulating buildings. Andrew Mitchell: “Woodfibre insulation, like the Pavatex range that we supply, is often the system of choice for timber and CLT projects, and well as the environmentally-focused projects for which you’d expect it to be the solution of choice due to the low embodied carbon thermal performance benefits. Current market conditions affecting other types of insulation are now prompting specifiers to look more closely at the benefits woodfibre can offer in terms of performance, ease of installation, technical support and cost, which is taking woodfibre beyond the realms of ‘eco’ and ‘heritage’ to meet the needs of any project.” “The natural properties of woodfibre mean that it combines reduced heat loss with improved building comfort and low combustibility for a temperate yearround environment and low risk installation. It’s a sustainable choice made from renewable materials that delivers carbon lock up of 10 tonnes for the average new build dwelling, but current market conditions are prompting specifiers to focus on woodfibre’s buildability and performance credentials too, which is great news for us, the construction sector and building occupiers.”
Small and Perfectly Formed An ambitious project on a tiny plot in East London, showed an innovative approach to tackling London’s housing crisis by maximising a limited urban plot to create a ground-breaking home using SIPS technology. The two-bedroom house – that was featured on TV’s Grand Designs – showcases structural insulated panels (SIPS) engineering at its most complex and creative. JML Contracts, a well-established, NHBC-registered, family business was approached by Joe Stuart of Warehome Ltd, to support the SIPS build on a tiny 38sq m plot in East London. In his role as architect, developer, main contractor and future owner of the house, Joe designed a split-level home, built over six half-floors and engineered to maximise space. The innovative design used every inch of the tiny plot, incorporating both a basement and a roof terrace over six half-floors.
The client was determined that the house achieve Passivhaus certification, therefore ensuring that the building was thermally efficient was a top priority. He chose SIPS for its exceptional thermal performance and U-values. The very narrow site made this house especially challenging from an engineering perspective. After extensive research and discussions it was evidenced that SIPS could provide the best construction method to achieve both the low-energy ambitions and to ensure that the structure could be precisely engineered to maximise every bit of space on the limited site. JML Contracts engineered the whole house structure
38 | www.structuraltimbermagazine.co.uk | STMAG
and it was pre-built it in the factory to demonstrate how it would work and to ensure that the design would fit perfectly when it was constructed on site. The finished house is potentially the smallest two-bedroom house able to be built in London under the London SPG (Supplementary Planning Guide) and, crucially, has exceeded the requirements for Passivhaus status, having been engineered both to maximise thermal efficiency and to utilise every inch of the plot as well as incorporating cutting edge design. The narrow London city centre site was extremely tight, therefore every millimetre of space needed to be accounted
SIPS for. Specification testing for the project often came down to choosing a product that would give as little as 10mm of extra integral floor space. Using SIPS allowed the wall sections to be kept as slim as possible, with no additional bulky cavity insulation required. The use of SIPS furthermore minimised thermal bridging within the building, offering a fully airtight structure while maximising the internal floor area. With an airtightness result twice as good as the required 0.6 AC/H (air changes per hour) the house has been confirmed to be a Passivhaus and is testament to the effectiveness of SIPS. The carbon footprint was assessed using SAP software at the design stage, which illustrated the anticipated carbon dioxide emissions expected from the running of the building. The initial design SAP was around 85. During the development stage, the SAP calculation was re-run along with the energy modelling using the Passivhaus Planning Package (PHPP). The optimisation of the energy performance, along with monitoring the SAP rating, increased the SAP rating to the mid-90s. Along with being Passivhaus compliant, when the installation of the solar PV is completed, the SAP rating will achieve 100; essentially a carbon neutral building. The SIPs panels used by JML are BBA-certified and fully insulated, requiring a minimal timber sub-frame. This almost completely eliminates thermal bridging. The finished product consumes fewer materials than a conventionally built home, requires substantially less energy to maintain, emits less pollution and will result in a more comfortable living environment. An external timber-clad rain screen allowed the maximum external insulation while keeping the thinnest wall build-up possible to ensure the internal space was as large as possible. Additional steps were taken to ensure neighbours were aware of the logistics and
02 continuous updates were provided. The building was engineered in such a way as to reduce the need for heating and cooling. This approach resulted in passive solar design through which the sun’s energy has been harnessed, an insulated airtight construction method, and high-performance windows and doors. These elements were carefully engineered to ensure that the client’s energy demands were met without compromising the look and design of the building. For this project, JML Contracts took a ‘fabric first’ approach: the client specified that they wanted to build using SIPS from the beginning, therefore the energy demands of the project could be considered from the outset. While the traditional expectation of an ‘eco home’ is often an array of solar panels on the roof or sustainable forms of insulation, modern sustainable building needs to look at the fabric of a building, focusing on the design and construction techniques. The main component of the insulation is the core of the SIP which are also the primary structural loadbearing elements. These formed the external walls and the roof above ground level. Because the structural walls are SIPS and therefore incorporate insulation within the structural elements themselves, their thickness was less than would be needed to achieve the same thermal performance with other forms of construction. This maximised the usable floor area on a very tight site.
03 This project took an unsightly, rundown and structurally unsound coffin workshop that was a danger to local residents and replaced it with a sustainable and aesthetically pleasing family home. It featured on Grand Designs in October 2017 thanks to its innovative and trailblazing approach. It was the first time the programme filmed inside a SIPS factory and also the first time they had been given the opportunity to film in a house completely pre-constructed offsite. It has shown how very small plots in urban areas may be used for the highest quality of new sustainable dwellings and simultaneously help regenerate and enhance their surroundings.

Taking Timber to New Heights Multi-storey timber is a trend that has seen a number of innovative buildings rise across the globe, including the ten-storey SKAIO, where ZÜBLIN Timber worked on what is the tallest timber building in Germany.
02 With many years of expertise in development, production, delivery and execution of high-quality timber construction and timber engineering, ZÜBLIN Timber produces customised components in its own state-of-the-art own production facilities and work in close co-operation with local project managers, engineers and architects during the planning period. The ten-storey SKAIO high-rise in Heilbronn, based on a design by Berlin-based architectural firm Kaden+Lager, is built by Stadtsiedlung Heilbronn GmbH and ZÜBLIN Timber. The SKAIO is Germany's first timber high-rise building and another milestone in multi-storey timber construction.
The 34m building, was erected as part of the city exhibition for the BUGA 2019 horticulture show in Heilbronn, with an above-ground gross floor area of 5,685m² and offers space for 60 rental units with a total of 3,300m² of living space. The design for the SKAIO project was awarded to Kaden+Lager – a specialist in urban timber construction for many years and has designed several timber and timber hybrid buildings for a number of different clients. A major advantage of timber construction is the relatively short time needed for construction, as the timber elements are largely prefabricated and merely require mounting and assembly onsite. “We build one floor a week,” says Markus Brandl, Project Manager at ZÜBLIN Timber. “The supports for the new buildings are made of glulam timber. For the timber walls and ceilings, ZÜBLIN Timber uses only spruce – mainly from German forests and is fully PEFC-certified.” That is an important requirement for additional certification as Stadtsiedlung Heilbronn GmbH applied for gold certification for SKAIO from the German Sustainable Building Council (DGNB).

ZÜBLIN Timber has also proven its expertise on 3xgrün – a five-storey residential complex in Berlin. This pioneering project in multi-storey timber construction, saw the company manufacture the timber components for the wooden house prototype, created by a research project and combined them with concrete semi-finished parts. This made the precise construction possible which has been awarded with numerous prizes. Further proof of ZÜBLIN Timber’s credentials can be seen on the Treet project in Bergen. For this project ZÜBLIN Timber partnered up with local specialised Moelven Limtre. This 14-storey residential tower, consisting of load bearing glulam and CLT members offers space for 62 apartments with a total area of 5,600m² and is famously regarded as the world’s first skyscraper in wood. ZÜBLIN Timber were also pivotal in the seven-storey Neubau Müggelstrasse, Berlin. The house has timber-concrete composite ceilings and load-bearing steel-concrete walls. The exterior walls are constructed as highly heat-insulating timber walls with a shingle facade. The residential building is accessed from the street by a single safe staircase and contains parking in the basement. The first residential level is on the raised ground floor. Altogether there are 42 apartments between 30m² and 122m² For more information visit: www.zueblin-timber.com IMAGES: 01.

Timber – a tool for healthy learning Tate Harmer has completed an innovative new science and arts building at Cranleigh Preparatory School that maximises student wellbeing to enhance learning and showcases glulam and timber technology. and interact with it. This new building on the school site will improve learning and set the tone for the future development of Cranleigh.”
01 Working on behalf of design and build contractors Blue Forest, Tate Harmer’s unique project is situated within the heart of the site’s open green spaces providing a healthy and natural learning environment for its students. Tate Harmer’s aim was to capture the ethos of the school – a soul and spirit that inspires.
02 trusses leaning together to facilitate large open spans beneath. An open deck at first floor doubles as a cricket pavilion to support activities on the adjacent fields.
Situated in the Surrey countryside, the building’s efficient layout replaces two existing buildings, relocating the art classrooms and providing new stateof-the-art education facilities including three new science labs, dual aspect art classrooms and a home economics room. A new circulation route around the building ensures that all teaching rooms open to the outside, increasing access to the outdoors, with no internal corridors.
Ridges on either side of the building respond to the site: a projecting south ridge provides rain cover and solar shading and a raised north overhang offers expansive views to the cricket pitch. Tate Harmer has installed two staircases: one central to the new building which connects to the new access route into the school and one on the North West corner of the scheme which connects to the existing exterior colonnade. Carefully selected materials are used to create a warm and natural environment with the extensive application of timber matching the tones of the surrounding environment.
Reflecting the healthy ethos of the school, the scheme provides a sustainable and low-energy/low-cost learning environment, naturally ventilated with high levels of daylight and fresh air. The building comprises two offset timber-clad blocks and an innovative ‘floating’ vaulted glulam roof conceived as a series of structural

Research conducted by the University of Salford in 2015 offers a number of recommendations on how to create optimum learning environments with the key aspect being ‘naturalness’, meaning a space must provide good natural daylight and ventilation to create a sense of physical and mental comfort for its users. Tate Harmer adopts this approach to ‘naturalness’ throughout the scheme and explores how linking internal learning spaces to a natural landscape can help with education, learning and collaboration. This project for Blue Forest at Cranleigh Preparatory School demonstrates an architectural approach that finds and responds to a natural affinity with the landscape, addressing the needs of the school for enhanced facilities, without impacting negatively on its green assets. Michael Wilson, Headmaster of Cranleigh Preparatory School added: “Tate Harmer have suggested innovative solutions for the heart of our campus and designed a building that is architecturally interesting, functional, flexible and sustainable.” For more information visit: www.tateharmer.com

laminated timber (CLT) are now on as a sustainable, structural alternative to steel and concrete.
Creating New Timber History Cowan Court is a three-storey building that takes its cue from traditional English and European timber-framing techniques and has used glulam to give the Grade II-listed Churchill College a new contemporary lease of life.
01 Cowan Court is a 68-room hall of residence and the first completely new court since the college was founded as a memorial to Sir Winston Churchill in the early 1960s. Churchill College was a pioneer in the radical expansion of university education in the post-war period, and for British architecture in general. The new hall of residence inverts the traditional relationship in Cambridge between court and courtyard – instead, private lawns typical of a college setting surround the building with bedrooms that face out onto views of the expansive
grounds and cricket field. The interior courtyard is filled with a forest of birch trees, offering a shared space for refuge and meditation. Cowan Court evolves many features of the original college buildings. The untreated reclaimed oak cladding echoes the textured board marked concrete and the colour of brick in the original college. New pale oak adds refinement in the lining to the cloister and triple-glazed windows. In summer, the densely planted birch forest within the court shades an informal garden for students to meet and study, which turns to orange
44 | www.structuraltimbermagazine.co.uk | STMAG
in autumn and opens to the sky in winter. The materiality of Cowan Court forms part of an ambitious environmental strategy: passive ventilation, triple glazing and super insulation reduces the amount of energy consumed in construction and in use. Solar electricity, solar water heating and rainwater collection reduce the energy requirements even further. Cowan Court responds to the original design in a contemporary timber construction. In three overhanging floors, the ‘jettying’ timber cuts recall the concrete bands across the facades of the existing courts. Each of the facades is curved like the entasis of a classical column, and the square windows of the student rooms spiral up and across, chasing around corners in playful misalignment. The exposed concrete structure of the existing courts provides a strong character and rhythm which is referred to in the new court. The structural frame is left exposed internally – uncommon for buildings of this type – and provides a richness and warmth to the student rooms. Glulam timber is used here in a way that it maintains a strong architectural presence. It is left unfinished so its laminated structure can be read. The oak cladding boards were reclaimed from railway freight carriages and form the exterior cladding, becoming a visible embodiment of sustainable design and creative re-use. The courtyard birch trees provide shade in the summer, while advanced solar coatings reflect heat from large areas of glazing further limiting heat loss and therefore running costs. The new building is forecast to produce a third of the carbon emissions of a 'standard student accommodation' building, and the Part L model predicts a CO2 emission rate of 42.1kg/CO2 compared to an existing standard residential accommodation building that would produce 115.6kg/CO2.

The foundational oak planted by Sir Winston Churchill in 1959 started a landscape which has grown alongside and within the original Brutalist courts. The new building inverts the spatial and material order of the picturesque Brutalism of the original college, shifting its mineral world of brick and shuttered concrete to timber. Cowan Court’s timber, both new and old, defines its structure and in turn encloses a central court filled with recently planted birch trees. Architects 6a were drawn to glulam for its speed of erection, accuracy of prefabrication and energy efficient properties. Cowan Court was conceived as a doppelgänger: an unidentical twin which has a familiar scale and character but whose construction reflects the time in which they were made. This set up a series of material translations – the timber board-markings on the original concrete become the actual grain of the glulam lamellas. Each iteration carries the memory of the previous. For the cladding a system of prefabrication was employed, applicable to Cowan Court due to the repetitive nature of its facades. Once tested, refined and decided upon, this system allowed 900m² of cladding to be hung in a matter of weeks, comparable to a more mechanised cladding system such as fibre cement.
The project was extensively drawn in two and three dimensions throughout the design process. 6a completed a fullydeveloped set of 2D technical drawings for the various sub-contractors alongside a comprehensive 3D model of the structural frame. The slightly curved facades were calibrated carefully through digital as well as physical modelling, where the properties of the timber structural elements could be replicated accurately. The square plan resulted in a pin wheeled structural grid, meaning in corners the structure was at differing points overlapped and truncated.
beams, columns, CLT floor decks and shear walls assembled as a kit of parts using proprietary bracketry.
As the glulam frame remains visible internally with no finishing, the accuracy and elegance of these connections was paramount, and made possible only through the use of sophisticated software. The specialist glulam engineers constructed a full BIM model – complete with all screws and brackets – and ran complex tests for load-bearing and deflection. From this model was generated some 200 detailed drawings, which after checking by architects, engineers and main contractors, were fabricated to precise tolerances and delivered to site in batches, dovetailing with the contractor’s programme and reducing time and wastage onsite. No adjustment nor re-fabrication was required, with the

The original client brief called for a contemporary building of exemplary architectural merit and the highest possible sustainability properties, which was in keeping with the existing listed college. Cowan Court can be seen to satisfy that criteria, providing a model for building characterful timber buildings of presence and permanence in historic contexts. For 6a and the college the relationship to landscape was of primary importance. There is an intensity of detail and craft, borne of a careful looking at the existing building as well as the history of timber framed buildings in the UK. For more information visit: www.6a.co.uk

An Emerging Reality Mike Chaldecott, CEO of Saint-Gobain UK and Ireland and Chair of the Construction Leadership Council (CLC) Innovation in Buildings workstream discusses the huge significance of offsite delivery. The importance of offsite manufacture has long been recognised in the construction industry and has become a key strategic component of the CLC’s vision for a transformation of the sector – something that we envision will be driven by a focus on digital, manufacturing and whole-life performance. It’s also a key focus for the Government’s Construction Sector Deal which includes a £170 million research and development fund for transforming construction. Five Government departments are also now working closely developing a presumption in favour of offsite construction by 2019. Many of the contributors to our report agree and see offsite manufacturing as a chance for the industry to improve the quality and quantity of houses in the future.
The construction industry is facing a time of unprecedented change. Thanks to external factors such as socio-demographic pressures and advances in technology there’s a host of challenges, and potential opportunities, unfolding for the sector. But which approach or tool is likely to become ‘the new normal’ – and how will it affect our industry? That’s what our report, ‘Emerging Realities in the Construction Industry’ set out to explore. The report is an overview of selected areas where new realities are emerging in the construction sector, using statistics and opinions from industry players across a wide range of disciplines to look at the issue from multiple perspectives.
48 | www.structuraltimbermagazine.co.uk | STMAG
As leader of the Innovation in Buildings workstream of the CLC, it is essential to progress the use of ‘smart construction’, of which offsite manufacturing is a key part. For me, this is about modernising the sector by removing the barriers to innovation to increase the number of homes built and enhance productivity, whilst improving quality and whole life performance. The Construction Sector Deal is so important for the industry because it encourages precisely this kind of transformation making our sector fit for the 21st century. With its launch, the CLC and industry will have access to further resources to accelerate the adoption of smart construction through innovation and collaboration.
OFFSITE MANUFACTURE The joint investment by the Government and Industry – over £420 million – is a huge opportunity to embrace more digital technology, to speed up the use of advanced manufacturing in construction and will result in more innovation, better careers and enhanced skills. All of which will be delivering better performing buildings, built faster at a lower cost and offsite manufacturing is key to the success of this transformation. As we know the skills gap is a very real crisis facing our industry. In our report Mathew Holloway, CEO of tech company Q-bot, discusses the potential effect of new digital technology on the skills gap. He says that the company was born to revolutionise the way workers construct, maintain and upgrade buildings by developing robotic tools which can operate in hard-to reach or hazardous areas. He says: “The drive to provide more intelligent tools and smarter processes will change the industry and create new, more interesting jobs. Moving a joystick on a game pad is a new kind of construction craft that future generations of construction workers will use.” The creation of new roles within construction is something that could not only attract new blood to the industry and enhance diversity, but also potentially allow employees to keep working for longer if some of the jobs are of a less physical nature. Offsite manufacturing plays a huge part in what the future workforce of the industry could look like. According to research from the ‘Modernise or Die’ report the potential decline in available labour force within a decade is 20 – 25%, a figure which could be even higher depending on the outcome of Brexit. This reveals yet another grave problem in our sector – which offsite could form part of the answer to. What’s clear is that the adoption of an offsite approach has great potential to move the dial and bring our industry into the digital age.
03 At Saint-Gobain UK and Ireland we’ve recognised the rising importance of offsite manufacturing. We’ve developed our own offsite solutions for building structures through strategic partnerships, via the evolution of existing Saint-Gobain brands, whilst also adding an offsite manufacturer to our broad portfolio spanning construction products, building distribution and innovative materials. We completed the acquisition of Scotframe Limited earlier this year accelerating our involvement in the offsite manufacturing and closed panel construction market. Further evolution is planned to complement our growing offsite proposition. I’d like to thank all of the contributors who took part in the formation of this report. Business thrives on foresight and I hope
this report helps spark a debate about the future of our industry. Specifically, how we all might prioritise our thinking and activity across our industry to maximise the opportunities at our fingertips and capitalise on the vast potential of our sector.

Stagecraft â€“ timber and theatre design Prefabrication offers distinct advantages in construction, but in theatre design, offsite construction can help clients deliver superb structures in less time. Simon Ricketts, architect at Haworth Tompkins explains how they found new ways to make two buildings perform better. Timber has always had a place in the making of theatres, particularly in northern Europe, and a connection with this tradition is key in designing a modern theatre. Two different theatre projects by Haworth Tompkins illustrate how timber can be used to make public spaces. The Perse School in Cambridge commissioned Haworth Tompkins to design a performing arts centre, and the brief asked for a welcoming foyer, state-ofthe-art auditorium, classrooms, workshops, and rehearsal and exhibition spaces.
The foyer incorporates the rehearsal room and exhibition space, so that the foyer can expand to include them when they are not in use. The upper parts of the foyer including the rehearsal room are expressed as a timber volume, faced in glass, sitting on a heavy concrete and masonry base. The building addresses a landscaped courtyard, as well as two routes to the sides. Again, the timber diagrid is used to offset a directional emphasis and refers to the timber structure of the original school buildings.
52 | www.structuraltimbermagazine.co.uk | STMAG
The roof is composed of sections of laminated veneered beech, doweled onto a node formed around steel cylinders by Constructional Timber. Lighting points are connected and wired through these tubes. Acoustic absorption is contained within the coffers as at the deck, making the roof structure an efficient acoustic soffit. Racking strength is provided by sheets of lapped plywood fixed to the top of the diagrid, forming the roof deck. At the junction with the masonry wall of the auditorium, steel brackets fixed into the masonry are flitched into the timber
CNC MACHINING CENTRES FOR TIMBER CONSTRUCTION
SCM is able to provide high technological cnc machining centres for the construction industry. Structural beams and modular elements of wooden walls are produced with extreme accuracy and rapidity thanks to Oikos and Area. The innovative structure with 6-axis architecture allows any machining operation on all faces without revolving or repositioning the workpiece. SCM Maestro Beam&Wall software permits easy interface with most CAD programs used by customers, thanks to the import of BTL files, the most common format used in timber construction.

members. An equivalent detail is used on the other three sides at the connection with the LVL columns. Steel brackets fixing the bases of the columns to the concrete deck are concealed within the floor. Beams and columns are lightly stained to match oak finishes, and the timber framed curtain walls. The oldest continually used theatre in the English-speaking world, the Bristol Old Vic was originally clandestine, the 1766 auditorium hidden behind houses and the 1744 Coopers’ Hall on King Street. Several additions to the front-of-house retained this peculiar civic relationship. The new foyer finally reveals the auditorium to the city, creating a deep and tall open public room with a glazed façade to face Bristol screened by openable panels, almost like a new external space. Crucial to the concept was the use of a timber structure, aligned to the surrounding existing buildings, tying
the various elements into a cohesive whole. The geometries of the existing buildings created a framework for the structural timber of the foyer, which are designed to drop in, touching existing masonry structures as little as possible; legibly new but crafted and human.
acts as the horizontal bracing. Each roof beam pairs with another beam at a column in a V shape, the column being a pair of rectangular glulam sections either side of spacers or flitches, depending on the structural requirement. Columns sit in steel shoes, which express just above floor finishes as a steel skirting around the column base. Timber members supporting floors are ‘oversized’ to account for charring, but also a response to the governing aesthetic of the foyer. The expressed timber structure of the gallery against the Coopers’ hall has a reassuring, almost medieval solidity.
This also echoes the auditorium, which is a glorious painted timber structure within a masonry box. Douglas fir glulam, flitched and with bolts expressed, was chosen as the structural material. Douglas fir has the warmth of softwood with the fine grain and almost knotless quality of hardwood, which is exaggerated by the glulam process. In the roof, the main timbers have no steel, with only the largest spans requiring steel reinforcement in the form of T flitches. Roof beams are designed to span in one direction, with the short spans connected with ricon connectors, allowing tight joints at any angle. The roof deck in plywood

The Role and Future of DfMA in the UK Design for Manufacture and Assembly (DfMA) is critical to the success of offsite technology and a new breed of construction thinking. Sarah Newine Moore, Project Manager at Eurban, illustrates a tale of two design methodologies. further efficiencies on the production line. Accompanying the development of the DFM and DFA software came the publication – Product Design for Manufacture and Assembly – and so the term Design for Manufacture and Assembly (DfMA) was born. DfMA is the combination of the two design methodologies: DFM (the design of individual parts of an assembly) and DFA (how to assemble all the parts to make the final product.)
01 In 1948 the industrial engineer and educator Geoffrey Boothroyd started his career as an apprentice in the Mather and Platt factory in Manchester. He would have worked with some of the figures immortalised in LS Lowry’s painting. This factory, a major employer in Manchester, produced mainly large centrifugal pumps. It was there that Boothroyd gained his insight into industrial production lines. By the 1970s, such production lines were radically changing and Boothroyd was teaching in the University of Massachusetts. His team’s research aimed to provide designers with tools to drive efficiencies in automatic and manual assembly of products in factories. This research
built upon other contemporary studies in European Universities and industry. Boothroyd and his team’s work resulted in a piece of software: Design for (Automatic and Manual) Assembly (DFA) for the Apple II Plus. Two of the world’s biggest companies, Ford and General Motors, claimed to have saved billions by adopting DFA, and interest in this design methodology grew exponentially. Boothroyd Dewhurst Inc. was established in 1983 and the team developed their next tool for designers: Design for Manufacture (DFM). This additional module of the software enabled a series of design options that could be accurately costed prior to manufacture, allowing for

The core principles of DFM are to simplify the design of a product by reducing the number of constituent parts, and by selecting the most cost effective materials and processes in their manufacture. While DFA aims to minimise the number of operations and therefore reduce assembly time and cost of a product. The success of the DfMA design methodology has led to its adoption across a wide range of professions including the construction industry in the UK. In the construction industry, DfMA relates to the prefabrication of building elements offsite in controlled factory environments for onsite assembly, enabling efficiencies in time, labour and cost. RIBA published the DfMA overlay to the RIBA Plan of Work in 2016. One of the key recommendations is to front-load the design process by bringing specialist subcontractors and consultants on board as early as stage 2 in order to discuss

03 buildability from the outset. This requires a significant shift away from more traditional forms of design and procurement. The industry still has a long way to go in this regard as the Farmer Review of the Construction Labour Model made clear – declaring in its title that the industry needs to ‘Modernise or Die’. Among the recommendations outlined in the Farmer Review are ‘pre-manufactured approaches’ – such as CLT/solid timber structures. DfMA methodology is integral to the design, manufacture and assembly of solid timber buildings and to how we work at Eurban. Ten years ago Eurban completed the installation of Waingels College, designed by Sheppard Robson. The term DfMA with reference to construction was not yet fully in use, however the adoption of earlier versions of the CAD/CAM software still used by Eurban today, enabled structural design options to be explored, agreed and integrated into the project. The architects co-ordinated and signed off the
drawings produced, and these were then manufactured by the factory offsite. Fast forward eight years to 2017. Eurban now adopts far more sophisticated software and more rigorous QA processes to deliver projects. Two recently completed buildings, Highpoint Terrace, a large eight-storey residential block in central London, and Frilford Golf club in Oxfordshire both employed advanced 3D BIM to develop the most efficient designs in terms of manufacture in the factory and assembly onsite. During the design phase of Highpoint Terrace, Eurban’s specialist timber engineers designed the most efficient structural solution, significantly reducing the number of elements by designing large 16m floor panels. A reduced number of operations onsite should lead to increased safety. 25% less labour was required to assemble this building, only eight site operatives as opposed to 35 if it had been a concrete structure. DfMA hand-in-

4D BIM gives design teams the opportunity to develop the DfMA methodology one step further. Both projects introduced the fourth dimension to the BIM models – time. The entire solid timber superstructure assembly can be modelled before work begins onsite. Crane locations and lifts, material set down areas, deliveries, and labour requirements can all be mapped out and communicated to the design team. This brings real advantages: sequencing issues and risks can be identified and addressed earlier, giving stakeholders and clients a high degree of insight and control over the process. The continued use and improvement of DfMA design methodologies should enable projects to become more efficient and enable government targets in the sector for greater productivity and lower emissions to be met. The solid timber industry continues to grow in this country, in Europe and globally. New production plants are opening for business all over the world while existing plants are increasing their capacity by extending and opening new sites. DfMA may require higher expenditure earlier in the design phase due to fees for specialists, but this early expenditure leads to greater predictability and therefore pays off during the build phase. When client bodies understand the longer term gain of early investment their projects should reap the benefits. For more information visit: www.eurban.co.uk

HOUSING & REGENERATION
Timber on the Record The Boiler House reimagines new styles of living and comprises of 54 balconied, studio, one and two-bedroom flats and is part of the Old Vinyl Factory regeneration site – named after the famous HMV factory that once manufactured vinyl records here.
lynchpin in the local authority’s plan to capitalise on the site’s musical history and the advent on the new Elizabeth Line (Crossrail) to regenerate a run-down part of their borough. It promises new housing, office space, shops, a cinema, a school, and lots of public amenity all unified around a new pedestrianised thoroughfare called the Groove. Fronting onto the Groove, the Boiler House connects seamlessly with the local community to the north and has excellent transport links, being just 20 minutes from Paddington and ten minutes from Heathrow and the motorway network. With its truncated pyramid forms and multiple balconies it is instantly recognisable and a true landmark for The Old Vinyl Factory.
01 The highly marketable design takes its cue and name from the boiler house that once supplied the HMV factory’s heating needs. The BREEAM Very Good building slots into the wider Old Vinyl Factory masterplan with quirky tapering external walls clad in shimmering stainless steel shingles that recall the area’s industrial heritage, while its
central orange staircase is an echo of the boiler house chimney that used to occupy the same site. The building is a striking feature in the wider Old Vinyl Factory development masterplan, a triangular site west of the Hayes & Harlington train station. It is a

Cross laminated timber (CLT) was chosen as the structural basis for the building after careful consideration of the available alternatives, of using steel or concrete frames. At a time when the more conventional elements of the industry were experiencing some overheating due to increasing demand, use of a new emerging method of construction offered the chance to achieve a number of goals. The speed of construction, on a tight site with restricted access, together with the certainty of supply of using factory made elements were very attractive. The inherent thermal properties, durability and stability of the timber structure all influenced the decision, agreed by Hub and Studio Egret West. It is interesting to note that the concrete framed building adjacent actually started well in advance, yet the Boiler House was able to complete first. CLT enabled the project to use a frame with advantages of programme and innovation, and a design which combines a number of striking features, raising the potential for sales. Architects Stride Treglown, were appointed by Squarestone Hub to develop the detailed design of the building, and novated to the contractor, Henry Construction Projects Ltd. Inheriting the project from the concept

architect, Studio Egret West, the design complexities were jointly overcome with Eurban – the CLT system designer. Accurately manufactured offsite, the CLT frame was erected in just seven weeks, overtaking other nearby housing projects to complete in May 2018. The fully BIM-enabled design work paid off: over 80% of the units sold off-plan, with the remaining flats set to sell quickly as the area regeneration beds in. CLT’s low embodied carbon, high values for thermal insulation and airtightness, and capacity for re-use or recycling in the future helped the building to its BREEAM Very Good rating. CLT’s good thermal and airtightness values keep energy loads low. Running costs are kept lower still because the flats are connected to the low-cost heating from the new district heating system. As CLT is comparatively light, it required six times fewer lorry journeys to deliver the material to site. For example, each tonne of concrete releases an equivalent of 1 tonne of CO2, whereas each tonne of CLT captures 2.5 tonnes of CO2. Timber has good thermal and acoustic insulation values, and is airtight when assembled. This greatly reduces energy use in the building and, combined with the energy recovering ventilation and because it is hooked up to
the district heating system, substantially reduces running costs. The use of CLT on this project was compared with other possible structural systems, principally concrete and steel frames. CLT was chosen for its advantages across a wide range of factors. It needed less substantial foundations, requiring only a concrete raft rather than a piled foundation. This alone saved weeks of programme time and several complex operations on a restricted site – both within itself and because of the access for larger construction vehicles.
fit-out processes. Because the CLT frame in this project is entirely encapsulated, the long-term maintenance costs are close to zero.
Unlike concrete, CLT frames are much faster to erect, need less in the way of infill walling and insulation, embody far less energy, and can be reused or easily recycled. While steel frames are faster than concrete, it also has high embodied energy, and requires complex thermal isolation and fire protection which are not such major considerations with CLT. Because CLT is manufactured in the controlled environment of a factory and assembled quickly on site by specialists intimately knowledgeable about how it fits together, the overall health and safety challenges are significantly lower than either steel or concrete. CLT’s quality assurance and speed of erection also improves overall programme time. Because windows can be fitted in advance, the envelope can be completely watertight early on, speeding up and protecting the internal
With a remarkably successful collaborative relationship between architect and system designer at its heart, the building resolves multiple complex phasing and technical issues to deliver an accurate building on time and to budget. The use of sloping elevations, so prominent a feature of the design, is very unusual in this kind of building and particularly difficult to achieve with CLT. It sets a new standard for architectural design and technical delivery, taking full advantage of CLT’s considerable advantages. The Boiler House shows how CLT can be successfully used on adventurous and unconventional projects. As such, it is an exemplar for the technology’s future promise not just for driving down programme times, reducing embodied carbon, improving recyclability, reducing environmental impact but also for its design flexibility.
