GROWING UP IN LONDON On 21 June, Steve Watts partner at Alinea Consulting will be chairing the Tall Buildings Conference which is being held at 22 Bishopsgate. Here he considers how London is continuing to ‘grow up’ and reflects on the transition from iconic landmarks to designing tall buildings with the user in mind.

The EU Referendum in June 2016 took place as the decision to proceed with 22 Bishopsgate was being made, provoking all kinds of risk analyses. Little did we know then what was to come as that building was nearing completion and beyond. The last two years have prompted us to reconsider how we live, work and play, and the current events in Ukraine are a stark reminder of the impact geopolitics can have on major construction projects, not to mention society at large. Rewind twenty years or so and the first phase of widespread, modern tall building development in London was commencing, on the back of projects like Heron Tower and The Shard negotiating the rigours of public inquiries. London may have been young in the global school of tall buildings, but it was offering an array of high-quality architectural and engineering forms. A decade later and there were debates about designing inside-out as opposed to outsidein, as teams compared the values of landmarks with the functionality and efficiency of more rational shapes. The argument progressed to the needs of the occupant. Latterly, tall buildings have had to foster contact and connection, health and happiness, both within them and in the spaces between them. 22 Bishopsgate was at the forefront of designing with the user in mind, as its website prominently states: “We imagined the building we’d




want to work in”. It offers 10% of its 1.5m sq ft as shared spaces that all occupants can use, backed by smart technologies and a building app that allows easy registration, continuous access, visitor management, and the booking of events and classes, among other things. The next generation of tall buildings will take this to the next level, using artificial intelligence to create frictionless spaces as well as new revenue streams. They will also place even more emphasis on permeability across the ground plane and up through the building, providing access to a range of floorplates, common facilities, generous terraces and biophilia. Iconicity still has value but the contemporary tall building must provide all the above with commercial efficiency, impeccable sustainability credentials and a well-managed and thoroughly-assessed set of impacts on its environs – not least the effects of wind. Fundamentally, design teams must rightly answer first: “Can we reuse the existing structures and reinvent the existing building?” if and before a redevelopment option is pursued – something that is now firmly part of the town planning process. Experts are currently grappling with the need to ensure that carbon calculations are consistent, understood and managed, whilst project briefs are beginning to be challenged: should the design life be extended? Can the building be made adaptable for future changes in use? Would occupiers be willing to accept a relaxation in

performance criteria, such as lift waiting times and comfort levels? Tall buildings have always been the most international of typologies, and the most politicised, having to marry the aesthetics of form and facades with commercial risks and realities as they navigate a sometimes tortuous route through planning. Now they must achieve so much more. London is continuing to grow up, evidenced by cranes on the skyline that are helping to build the latest wave of towers, and by numerous high-rise proposals yet to enter the public domain. They do so at a time of immense uncertainty as we find ourselves at various stages of crises, with changes in climate, politics and economics providing a cocktail of challenges and constraints. As ever, tall buildings find themselves at the forefront of contending with these challenges through their scale, complexities and longevity. These attributes, however, also present opportunities, which is why towers have historically been termed ‘laboratories in the sky’. Increasingly, investment in innovation and an ability to take a longer-term view is being applied beyond the red line of the tall building project, to encompass the ways in which these buildings and their host cities can work together to create sustainable vertical urbanism. In a world where existential questions are being raised – of the need for tall buildings, of offices, of cities even – answers have to

Buildings M Tall

be genuine and properly assessed. It would seem that those high planning hurdles in London are being raised even higher, but for good reason. The key to ensuring that the capital not only maintains its status as a global financial centre but improves its standing as a liveable and sustainable city will be collaboration between policy makers, policy enforcers and project sponsors, to ensure consistency in evaluation of proposals and the contributions they make to the wider city. These contributions should aim to make cities more equitable: the ‘S’ of ESG (Environmental, Social and Governance) cannot be ignored. Tall buildings are now part of that narrative: housing that is truly affordable; offices that are inclusive; mixed-use developments that encourage a community feel; a public realm that is welcoming. As the bar is raised, a few obstacles have been placed on the track, with supply chains disrupted, inflation rampant and skills in short supply. It is just as well that the creators of tall buildings love a challenge! Alinea Consulting Alinea believe there is a better way to provide construction cost advice, and always strive to improve delivery of service – guided by a clear vision, strong values and the best people.

INDUSTRY NEWS Buildings M Tall Planning Consent for New 26-Storey Residential Tower

Covent Garden Redevelopment Scheme VINCI UK Developments /St Modwen (VSM)

St Modwen Developments has secured planning consent for a new residential tower in Nine Elms, London. Designed by Glenn Howells Architects, the new project will feature 201 new homes. The joint venture between VINCI UK Developments and St Modwen (VSM) is transforming a 57-acre site to deliver a world-class development, significantly contributing to the cultural and economic regeneration of the Vauxhall, Nine Elms, and Battersea area. VINCI UK Developments Managing Director, Graham Lambert, said: “This planning consent represents a key milestone for the VSM partnership, and the

redevelopment of New Covent Garden Market, highlighting our key priority of designing sustainable developments, which will create a positive legacy.” The new 26-storey scheme Apex 1 will feature 201 new homes and retail space on the land released due to the New Covent Garden Market redevelopment project. The first building on the wider Apex development location has outlined approval for additional commercial space, as well as 422 homes. Apex 1 will feature a two-storey pavilion, accommodating ground floor retail, a first-floor amenity area, and a roof garden. It will also provide a

permanent landscaped pedestrian connection between Nine Elms Linear Park and Nine Elms tube station. St Modwen Developments Senior Development Manager Nick Smith said: “Apex 1 promises to be a high-quality new scheme for Nine Elms. This latest planning decision means we can deliver new homes for the area while achieving another important milestone for the transformation of New Covent Garden Market.”

Edinburgh City Council to Undertake £1.8m Survey of High Rises Edinburgh City Council has approved an investigation into the condition of high rise buildings in the city. The council predicts there will be ‘a range of technical and financial challenges’ in upgrading Edinburgh's multi-storey flats, which were built between the 1950s and 70s. As part of plans to make council homes net zero by 2030, project management firm Faithful+Gould has been awarded a contract worth £1,882,207. The company will complete a detailed investigation of 36 multi-storey blocks designed to identify any structural defects. A report to the finance and resources committee, which approved the contract, stated the towers were built using a range of construction methods which now require detailed investigation and


surveys to assess the condition of the structures. This investigation has to be carried out by structural engineers with extensive specific experience in these construction types. Findings from the wide-ranging survey will be reported back in 2023 and will give an overall picture of the condition of the buildings as the council prepares to invest in upgrades for social housing to improve energy efficiency and meet climate targets. Around 3,000 of the city's 20,000 council homes are in 44 high rises throughout Edinburgh which were all built between 1952 and 1976. May Court, Gunnet Court, Craigmillar Court, Peffermill Court, Citadel Court, Persevere Court, Saunders Street, and Westfield Court have already


had full structural and condition surveys and will therefore not be included in the review, which commenced in April 2022. Faithful+Gould have appointed engineers Will Rudd Davidson as sub-consultants to undertake the core structural engineering function of the survey. The report notes the Edinburgh-based firm has worked extensively throughout the city and has a good understanding of the council’s multi-storey blocks due to previous structural engineering commissions. The City of Edinburgh Council will borrow the £1.88m needed to fund the review, paid back in yearly £107k instalments over 30 years.

INDUSTRY NEWS Senior Figures Gather for Topping out at One Centenary Way

Chris Taylor, Chairman MEPC and Chief Executive of Real Estate at the international business of Federated Hermes, said: "Today is a celebration of the efforts and extraordinary collaboration by the development and construction teams to bring One Centenary Way to life. This exemplary building sets the standard for future development in the city centre and is a space that's already contributing to regional growth, attracting jobs, skills and investment into the centre of the city for the well-being of local people and the community." Councillor Ian Ward, leader of Birmingham City Council, added: "Watching One Centenary Way rise from the ground up has been of interest to many people and I think we can all agree today on how impressive this major new landmark for the city looks. But it's not just a building in place for its own sake, it is creating and sustaining new jobs for the people of Birmingham, new skills and opportunities for all, and a landmark we can all be positive about."

One Centenary Way, Birmingham Glenn Howells Architects Designed by Glenn Howells Architects, with engineering input from Arup – One Centenary Way, Birmingham is more than 26,012sqm spanning 13 floors, including a two-storey basement which extends over the entire width of the Queensway

Tunnel below. Senior figures from parties involved gathered for a topping out ceremony for the major commercial building, which forms part of the £1.2bn Paradise Birmingham development.

The Paradise development Birmingham is providing up to ten flagship buildings, offering offices, shops, bars, cafés, restaurants, a hotel and Octagon, alongside a 49-storey octagonal residential tower.

Bishopsgate Goodsyard Scheme Finally Gets the Green Light Following a vigorous campaign opposing plans to build 1,400 homes in towers of up to 46 storeys, the developers of the Bishopsgate Goodsyard site were forced to go back to the drawing board in 2016 after GLA officials recommended refusal. The drastically revised 500-home Faulkner Browns, Eric Parry, and Buckley Gray Yeoman scheme finally got the green light after planning approval was granted by the London mayor. The new master plan for the Bishopsgate Goodsyard development, drawn up by Faulkner Browns, includes 10 buildings and just over a third as many homes, with a 29-storey office block designed by Eric Parry Architects marking its highest point. As well as housing, the scheme includes 131,000sqm of space for business use and an 11,000sqm hotel, plus a further 18,400sqm of retail, financial and professional services usage. It will also get a New York-style high line park. Sean Mulryan, Chairman and Group Chief Executive, Ballymore said: “The Goodsyard site will be the jewel in the crown of Shoreditch. We bought this site almost 20 years ago when this area was a very different place. As the last opportunity for significant growth in

Bishopsgate Goodsyard Scheme Eric Parry Architects Shoreditch, the time has come for what will be a great boost to the local area and London. With a mix of new homes, sitting alongside workspace, shops, cafes and restaurants, cultural buildings, new streets, and one of central London’s largest new parks – this will be a place designed with wellbeing in mind, where people want to live, work, and enjoy themselves.”

Sadiq Khan gave backing in principle to the scheme at a public hearing in 2020, however the Greater London Authority has now finally issued legal planning permission, listed building consent, and a section 106 agreement for the major redevelopment of the City fringe site, which sits on the border of Hackney and Tower Hamlets.



INDUSTRY NEWS Buildings M Tall One of the World’s Tallest Modular Towers Gains Approval

New Canary Wharf Student Accommodation Scheme Tide Construction/EPR Architects Plans for a 48-storey tower built using modules manufactured offsite were approved by Tower Hamlets councillors this week. Tide Construction, the developer behind the world’s tallest residential modular building, submitted them.

four amenity levels and a roof garden. According to the officer's report, using offsite construction could reduce construction waste by up to 80%, with 97% of the waste being recyclable - although the scheme will require the demolition of the site's currently vacant seven-storey block dating to the 1990s.

Tower Hamlets planning committee voted seven to one to approve the Canary Wharf block, backing a recommendation for approval given by the planning officer. Objectors questioned the necessity of a student accommodation building in the area as there is no university in the local vicinity, suggesting it would be more sustainable to refurbish the existing building.

EPR’s tower is to be built using prefabricated modules that will be transported to Marsh Wall and stacked on top of each other. Tide used the same technique on a pair of 38 and 44-storey towers in Croydon, which made headlines last year when they became the tallest modular buildings in the world.

Designed by EPR Architects, the student accommodation scheme at 30 Marsh Wall will house just over 1,100 studio apartments, including

Tide is now building an even taller 50-storey scheme on a neighbouring plot. All three Croydon towers were drawn up by HTA Design.

40-storey Skyscraper in the Making for Nottingham City Centre

Victoria Works, Nottingham Code Students



Other firms working on the project include modular contractor Vision Modular, landscape architect Spacehub Design, daylight consultants Avison Young, planning consultant Rolf Judd Planning and structural engineer Barrett Mahony Consulting Engineer. Their vision is to bring forward a landmark building of exemplary design, adding positively to the existing skyline in the Marsh Wall area. Tide will also be working to improve the local public realm surrounding the site, including improving planting and access to Cuba Street and the proposed new Cuba Street Park.

According to planning research group Urban Nottingham, the planned construction of a 40-storey student accommodation tower at the former Base 51 site off Huntingdon Street and Glasshouse Street would make the skyscraper the city's largest building. The Victoria Works development would house more than 1,500 students and tower above the Victoria Centre flats, which is currently the tallest building in Nottingham at just over 20 floors. A planning application is yet to be submitted, however a spokesperson for developers Code Students, said: “Code has been seeking to develop a scheme in Nottingham for several years. We have been in contact with the Local Planning Authority with a view to bringing forward a development in the city. We are currently working up our plans for Nottingham. Once we have a sufficiently developed scheme, we will be engaging further with the Planning Authority and embark on a public consultation ahead of submitting a planning application.”

INDUSTRY NEWS Buildings M Tall Two More Skyscrapers Approved by Manchester Council

Plans for apartment blocks have been approved by councillors despite featuring no affordable accommodation. Due to build two skyscrapers near Deansgate, Renaker Build, however will pay £500,000 for a new school and £90,000 for affordable housing elsewhere in Manchester. Designed by SimpsonHaugh, Renaker’s latest tower project features 988 one, two and three-bedroom apartments. According to the developer both towers feature chamfered edges, incrementally increasing and decreasing every five storeys, creating a dynamic vertical movement up the tower. According to Renaker’s viability appraisal, the project has an estimated GVA of £370m, and will cost around £329m to build, based on a predicted developer’s margin of 10.98%. The scheme's location is close to the four-tower 1,500-apartment Deansgate Square, which is complete. Renaker is also behind plans for the four-tower Trinity Islands cluster, also in Manchester, approved earlier this year. This scheme will provide almost 2,000 apartments. In Salford, the developer is bringing forward Colliers Yard as part of a three-tower master plan in the city’s Greengate quarter.

Canary Wharf to Build Europe’s Biggest Commercial Laboratory

The joint venture between Canary Wharf Group and Kadans Science Partner involves the development of a 22-storey tower on the North Quay site. With 750,000 sq ft of space the building is earmarked to be delivered in 2026 and will become the largest commercial wet lab-enabled life science building in Europe. The scheme will create a campus housing small and medium-sized enterprises and academics, as well as global healthcare and pharmaceutical companies.


Dutch company Kadans Science Partner, which specialises in building lab-ready properties, has set-up a joint venture with the Canary Wharf Group. Once complete, the building, thought to cost around £500m, will be home to thousands of workers and house up to a hundred businesses. James Sheppard, Kadans’ UK Chief, said: “We are effectively going to be building a campus under one roof. A lot of clinicians now are also entrepreneurs, they want to build a business.”


The new development will be on a similar scale to the Crick Institute, the biomedical research facility established by London universities in 2016. However, the Canary Wharf development will focus on commercial applications of science. Howard Dawber, Head of Strategy at Canary Wharf, said: “There is huge demand for this, labs in London were already at capacity with a vacancy rate of just 4% in Oxford and 1% in Cambridge.”

INDUSTRY NEWS Buildings M Tall More Than £1bn Worth of Construction Work in Leeds

Leeds city centre – the highest level of residential building since its records began in 2007

More than a billion pounds worth of construction work in Leeds is either on site or due to start this year. Residential work is driving this boom according to Glenigan’s construction industry analysis. Deansgate Exterior HG Construction started in February on the Renaker £60m Merrion Project to redevelop a former Santander office into 660 student accommodation units (Project ID: 20166413). It will be built across two blocks – the tallest will be 32 storeys high and the second 11 storeys. Developer Rushbond recently won planning permission for a high-rise scheme set to provide 1,000 homes on the site of a former Goods’

Yard (Project ID: 19033857). Rushbond Group is working with residential developer Gold & Amber on the Leeds City Village. With work expected set to start this summer, a contractor will need to be appointed soon. Other projects coming up include developer Downing’s £100m proposal for 1,200 student rooms in a 38-storey tower near Leeds Arena (Project ID: 21396637). A planning application has been lodged and work is due to start later this year.

Dan Batterton, senior fund manager for BTR at LG investment management, said: “As Covid-19 drives secular changes and a fundamental rethink of many areas of the real estate sector, BTR has remained largely unaffected. It has delivered stable income returns throughout the crisis, with occupancy, rent collection and demand remaining high.” Deloitte’s latest Crane Survey for Leeds city centre found the highest level of residential building since its records began in 2007 with 2,267 new homes under construction.

Build-to-rent (BTR) is having an impact. Legal & General (L&G) is investing in the £57m Tower Works development being developed by ASK and Richardson (Project ID: 14145578).

Liverpool Set for New £35m ‘Eco-Trailblazer’

HEMISPHERE – Liverpool’s first proposed operational net zero carbon building. Image: Sciontec

Liverpool’s first operational net zero carbon building known as Hemisphere was launched earlier this year. Located in Paddington Village, the proposed £35m building will feature 116,000 sq ft of innovative, Grade A office space for health, education, science and tech occupiers. The eco-friendly building which will be delivered by Sciontec, will aim to achieve an excellent rating for BREEAM (Building Research Establishment Environmental Assessment Method). Just 10% of buildings in the UK have this rating. The scheme, which will be subject to an independent valuation of the plot of land before a 150-year lease is granted to Sciontec, is seen as critical to the city’s recovery by encouraging job creation in the health, science, research and education sectors. It is estimated Hemisphere will create up to 800 new


jobs in the knowledge sector and support up to 100 apprenticeships during its construction phase. Depending on cabinet approval, the next step after the agreement is entered into would be for a planning application to be submitted in mid-2022 with an expectation that Hemisphere’s construction would begin later that year and be completed in late 2024.


Sciontec was established by Liverpool City Council, the University of Liverpool and Liverpool John Moores University, with Bruntwood SciTech joining as a fourth equal partner in May 2020. Its core mission is to build on Liverpool’s world leading strengths in education, medicine, science and technology by developing the best workspace and laboratories in the country.

Offsite Modular Specialist Appointed on £100m London Scheme Offsite modular specialist Elements Europe has been appointed as the Main Contractor on a £100m central London hotel and office scheme. Funded by UBS Asset Management Real Estate & Private Markets (REPM), development partners BSW Land and Property and The Pickstock Group – the central London scheme in East Road will provide five-storeys of high-quality offices below a 17-storey volumetric modular Motel One hotel. The development will deliver on the Environmental, Social and Governance (ESG) goals of its stakeholders, with the majority of the superstructure constructed by prefabricated modules, minimising environmental effects and disruption thanks to fewer site deliveries, reducing noise and pollution. The scheme will be delivered with less embodied and operational carbon than a traditionally designed development, having reduced waste levels and increased levels of fabric first insulation performance when compared to traditional construction methods. The office space aims to achieve ‘Excellent’ BREEAM certification, underlining the project’s sustainability credentials.

Perceptions surrounding the design of high-rise buildings in the UK are changing. Post-pandemic attitudes towards the way we live and work have given rise to questions about the future direction of the sector and what architects can do to embrace a more hybrid style of building usage.

Over the next few years tall building advocates will not only need to anticipate changes in the construction of high-rise developments to meet net zero targets but also in how work, leisure, and residential spaces integrate. Returning to Central London at 22 Bishopsgate on 21 June 2022 – the Tall Buildings Conference will showcase innovations driving the sector forward, providing an insight into revolutionary design principles and engineering prowess. The event will allow delegates to engage in networking and intelligence sharing with those at the forefront of technological advances. The conference will host an informative exhibition and speaker presentations covering everything from case studies to the effect of the zero-carbon agenda on tall building construction. Opening the event programme will be Steve Watts, Chairman of the Council on Tall Buildings and Urban Habitat & Partner of Alinea Consulting, kicking off an exciting line-up of high-profile speakers. Delegates will have the opportunity to acquire learnings from case studies such as South Quay Plaza, an iconic Canary Wharf waterside property presented by Ben Wheeler, Technical Director of Berkeley Group, alongside Rodolfo Giannini, Director of WSP. 14

TALL BUILDINGS WARRANTY AND BUILDING CONTROL PROVIDER PREMIER GUARANTEE TURNS 25 Manchester United won the league title, Tony Blair was Prime Minister and Harry Potter became a literary phenomenon. Yet 1997 was a landmark year for another reason – Premier Guarantee was launched. Now 25 and one of the largest providers of structural warranty in the UK, Premier Guarantee has become a major player in tall buildings construction. Premier Guarantee’s first high-rise (six storeys+) development was the eight-floor, 68-unit Tower Building in Liverpool. That was back in 2003. In the two decades since, the structural warranty and building control provider has helped construct 650 high-rise buildings in the UK, totalling almost 6,500 storeys. Taking an average floor height of 3.75m, that’s the equivalent of two-and-a-half Mount Everests. Premier Guarantee has developed a specialist team with the skills and experience required to deliver complex high-rise projects. Offering both structural warranty and building control services, it

has honed its processes and found significant advantages through early engagement. Initial meetings take place as early as RIBA Stages 0 to 2, and an early design review is offered at RIBA Stage 3. This ensures designs are compliant before construction begins. As David Richardson, Operations Director for Chalegrove Properties, the developers behind London’s 75-storey Landmark Pinnacle building told us: “We are very pleased with the way Premier Guarantee integrate themselves in the design process. Their involvement from the early stages all the way to the end is truly outstanding.”

Site inspections start at foundation stage and are tailored according to the needs of the project, with regular design reviews and a progress dashboard keeping you and your project on track. Policies provide cover from 10 years and include mechanical and engineering defects for plant installations as well as structural defects.

ALTUS HOUSE A NET ZERO CARBON LANDMARK In August 2021 Olympian announced completion of the tallest student accommodation building in Northern Europe – Altus House in Leeds.

Forward funded by IQ Student, the 37-storey scheme on Tower House Street incorporates 752 student rooms across a total of 23,662 sqm GIFA and has been constructed as a net zero carbon development. Starting onsite on 01 October 2018 with practical completion on 04 August 2021, the student accommodation was ready in time for the start of the academic year. The build programme took 34 months to complete despite


the challenges presented by the pandemic, construction continued whilst observing strict social distancing measures and the government’s health and safety regulations. The development has been built by RG Construction and the net zero carbon landmark was reached through offsetting using a gold standard verified emissions reduction scheme that is focussed on delivering wind power and renewable energy.


Olympian, specialists in sourcing and developing large-scale purpose-built projects, are committed to delivering high quality developments and the company's first net zero carbon building is a significant achievement and one that they are committed to replicating. The development will help to meet the considerable demand for student housing in Leeds and it is anticipated it will set a quality benchmark for student accommodation in the area.

The completion of this project marks another significant achievement for Olympian. Key Challenges July 2020 marked a key milestone with the final pour of the level 37 roof deck and parapet walls. In parallel the facade progressed simultaneously with Techrete panels wrapping the building as its enclosure progressed to a final conclusion. Internal fit-out followed maintaining coordination with the overall programme. The site constraints presented the main challenge for this scheme as the footprint is very restricted and bounded on all sides by highways and other buildings. Achieving lateral stability of a slender building was a critical design consideration. Construction sequencing was also a major challenge and the logistics of building the structure were given careful consideration, with designs being carried out for numerous temporary construction cases. The tower crane scheme presented a significant challenge due to the forces involved and the need to tie the crane to the building during the construction period.

Solution The structural solution included a reinforced concrete core located as centrally as possible whilst still being sympathetic to the architectural layouts, working in tandem with flat slabs and reinforced columns to resist significant lateral loading due to wind forces. A wind tunnel test was carried out to ensure accurate loading was used in the design, and to assess the dynamic response of the structure. The construction sequence involved a slip-formed core with temporary support from internal slabs, with the tower crane tied to the core and floor slabs at two levels. Student Life Towering over Leeds city centre, this 37-storey building is the tallest in Yorkshire and makes the most of the stunning panoramic views from the roof terrace on the 35th floor. Students are just a short distance from the university campuses, with Leeds Beckett and the University of Leeds within a 10-minute walk. There is a choice of en-suite rooms ranging between 13-17 sqm with larger accessible rooms available and self-contained studio accommodation of up to 22 sqm, along with some of

the best facilities in town. A cinema, private dining room and a retro arcade and games room add plenty of enjoyment to student life.

FIRE SAFETY IN TALL BUILDINGS Why specifying Euroclass A2 facade breather membranes will be essential for fire safety in high-rise buildings. From a fire protection perspective, a fundamental problem with curtain wall rear-ventilated facades is they represent an open system and in the event of a fire, flames and smoke may spread rapidly via the rear-ventilation gaps. As facade membranes mostly cover a large area of the building envelope, this can cause a high risk for fire safety, if not installed as a Euroclass A2-s1,d0 specification. Addressing the issue of the right facade membrane with water proofness, breathable with UV protection should form part of any overall facade fire strategy.

A complete external wall system in Euroclass A2 With Stamisol Safe One facade breather membranes (Euroclass A2-s1,d0) it is possible to design an external wall system completely in Class A2. Its high-class performance will cover not only fire safety but breathability and excellent weatherproofing W1 to guarantee that thermal insulation will keep its functionality and energy efficiency for the lifetime of the building.

NEW STEEL PANEL FACTORY WITH £37M UK INVESTMENT British Offsite’s new steel panel factory will include a £6m production line, delivered by Swedish manufacturer Randek AB.

The build is well on its way for the second British Offsite factory - a new 137,000 sq ft factory at the Horizon 120 Business, Innovation & Logistics Park, Braintree, Essex. The groundwork and framework have now been completed and the factory will be operational from May 2023. The company believes the new factory will deliver 4,000 homes per year. British Offsite adopts modern methods of construction (MMC) and specialises


in the design and production of superstructures and interior-fitout modules. After completing over 600 homes this year, in partnership with Weston Homes, its light gauge steel closed panel system approach reduces the time between breaking ground and first handovers by up to 20 per cent. The company says its modular design is compatible with traditional building designs. In addition, British Offsite’s approach helps manage the skills shortage facing the industry.


Managing Director of British Offsite Shaun Weston said: “The skills shortage in the construction industry was widely reported before Brexit, and now we’re in a post-Brexit environment where the pandemic has further reduced access to skills. With the work of up to five trades consolidated into our panels, customers like Weston Homes are more protected from the skills shortage and construction can continue unhindered.” “A good example of how this works in reality is Abbey Quay, Barking, a riverside development with 13 residential blocks ranging from seven to 29-storeys in height. The six-acre, 1,000 homes scheme will be delivered over the next five-years and will use the UNI-Panel, UNI-Wall systems alongside BOS Fitout modules throughout.

VICTORIA RIVERSIDE KICKSTARTING THE REGENERATION Victoria Riverside is a landmark mixed-use residential development that will bring 634 new homes to Manchester City Centre and form part of the first phase of the £1bn Victoria North masterplan.

of housing typologies including townhouses with front doors onto Bromley Street and maisonettes on the upper levels. Raised entrance terraces and external balconies animate the façade, providing private amenity and promoting social interaction between neighbours. The scheme offers a mix of tenures including shared ownership. The towers sit above a brick podium - a direct response to the backdrop of railway arches along the viaduct. The grid wraps down into the podium and mid-rise blocks expressed as a brick frame which opens up to accommodate double height shopfronts along Dantzic Street and a glazed residential 'super-lobby' facing on to the newly proposed Gateway Square. Principal Designer: Hawkins\Brown Planning Consultant: Avison Young Kickstarting the regeneration of Victoria North, the three sculptural towers will join Manchester’s evolving skyline while new public realm, landscaping, commercial spaces and townhouses will activate the surrounding streets to provide the catalyst for a new community to thrive. The brief was to develop a high density, landmark proposal that addressed the key principles from the Northern Gateway Strategic Regeneration Framework (SRF): improving connectivity along the main East-West axis. The Big Idea The placement and sculpting of the three towers allows the site to integrate with the wider district creating visual


permeability and key connections back to the urban landscape and to the natural features of St Catherine’s Wood and the River Irk.

Structural Engineer: Civic Engineers, RoC Consulting

The Detail The tower layouts have been designed to ‘stagger’ the arrangement of the homes and living spaces to respond to the geometry of the site whilst also maximising views across the Irk Valley and back towards the City. The towers accommodate 100% dual aspect apartments with a generous ‘picture’ window to each living space that frames key local vistas.

Contractor: CR Construction (UK)

The lower-level blocks along Dantzic Street and Bromley Street accommodate a diverse range

SIGNS OF A SLOWDOWN BUT THE FOCUS SHOULD BE ON QUALITY NOT QUANTITY The results of the 2022 edition of the annual New London Architecture (NLA) London Tall Buildings Survey, published in partnership with global property consultancy Knight Frank, indicate a downward trend in London’s tall buildings with applications down 13 per cent over the previous year.

The annual survey – now in its ninth year – provides the only comprehensive analysis of tall buildings in the London and offers a snapshot of how the capital’s skyline is evolving. The survey includes all buildings 20 storeys and above, which are either in planning or under construction. For residential schemes, current and historic data has been supplied by Molior London and commercial building data comes from


Knight Frank’s proprietary database. There are signs of a slowdown of tall buildings in London. The pipeline of 20 storey-plus buildings in the capital contracted 1 per cent year-on-year in 2021, while the number of new planning applications put forward by developers and new construction starts — bellwethers for the state of the market — came in lower than long-term trends.


A slowing is not entirely unexpected; a combination of the uncertainties created by the pandemic, rising build costs, new safety measures, environmental regulations and increased affordable housing obligations in recent years have imposed greater scrutiny on high-rise development.


Buildings M Tall

However, despite the slight decline in the overall pipeline, this year’s figures should not be interpreted as the end of tall building in London. As noted in previous surveys, what is coming through the planning system and out of the ground, is increasing across the outer London boroughs, in zones 3, 4 and 5, as well as for the Build to Rent sector, mirroring the trend in the wider new-build housing market. Commercial buildings account for 13 per cent of the total pipeline. Peter Murray, Curator in Chief at New London Architecture, said: “Signs of a slowdown in this year’s results is not entirely unexpected; a combination of the uncertainties created by the pandemic, rising build costs, new safety measures, environmental regulations and increased affordable housing obligations in recent years have imposed greater scrutiny on high-rise development and it has had a knock-on effect.”

Stuart Baillie, Head of Planning at Knight Frank commented: “This year’s figures should not be interpreted as the end of tall building in London. Quite the contrary. The survey points to a record level of permissions being granted last year, up 26% on 2020, and the number of completed projects was robust. Context is essential; the future pipeline may have contracted slightly, but it remains significant. In total, there are 583 tall buildings which are proposed or approved with 109 of those currently under construction, 28% and 19% higher than back in 2016 respectively. It should be London’s ambition to be a world leader in delivering exceptionally-designed and highly sustainable tall buildings – and the construction industry plays a vital part in achieving this goal. With this in mind, we should not focus on the quantity of tall buildings coming forward, but rather the quality. It is crucial that any tall building delivered not only positively contributes to the economy and sustainability of the capital, but also meaningfully adds value to its local context.”

DELIVERING THE PERFECT BALANCE The population of cities globally is continuing to grow, with the UN predicting that almost 70% of people will be living in urban areas by 2050. This means that more of us are living and working in high density areas, in large residential blocks, or commuting to high rise offices.

In short, occupants struggling with overheating are caught between a rock and a hard place – either increase their carbon footprint and energy bills or face a noisy night’s sleep or day’s work. What’s more, with the appearance of Covid there has been greater focus on the importance of natural ventilation in helping to keep shared spaces healthy with a regular flow of fresh air. This, in turn, has meant more occupants are now experiencing the distractions and disruptions of a noisy workplace in order to maintain a good level of ventilation. City living offers many advantages but there are also challenges, not least in how we keep our expanding city populations comfortable in their homes and workplaces whilst minimising the environmental impact. One issue that encapsulates this is overheating, where the temperature of a building regularly exceeds what would be classed as comfortable. There are multiple interrelated reasons for this increasing trend. On a simple level, larger buildings mean more heat is being generated through work equipment or keeping homes and leisure spaces warm. Some of this heat passes into other parts of the building, accumulating the higher up you go. In tandem with this is an unintended consequence of our drive to reduce greenhouse gas emissions (GHG). In the UK, for example, around 40% of total GHG emissions are understood to come from the built environment. This has led to the design of buildings


being more airtight, preventing heat loss and therefore reducing energy, such as gas, needed for heating. However, this also means that as buildings overheat, they now lack the natural ventilation that historically would have helped to keep them cool. Occupants are left with two options – either use an air conditioning system or open a window. Whilst air conditioning systems are effective, they of course require energy to run – meaning that an increasing reliance on them will negate many of the positive effects achieved through better thermal efficiency. Where windows are able to open, this clearly does not require energy usage, but does open a different dimension in building comfort – noise. In busy cities that ‘never sleep’, noise from traffic and other sources can be present around the clock, with window systems designed to mitigate this – provided they are closed.


We felt there must be a better way around the problem of achieving the thermal efficiencies we need in order to reduce GHG emissions, while allowing occupants to manage natural ventilation for both comfort and health. This led to a collaboration between Reynaers and Arup that involved experts from a range of related fields such as building envelopes, materials, sustainability, building physics, acoustics, and building services coming together to discuss the challenges. One potential solution was found in what has become our Masterline SoftTone® window. The range has been designed to provide superior air flow and cooling whilst attenuating sound to minimise noise in comparison with conventional window systems and eliminating the need for mechanical ventilation systems.
