Editorial This year’s Venice Architecture Biennale runs until the end of November. Its motto is “Reporting from the Front”. The Chilean architect Alejandro Aravena, who served as commissioner of the Biennale, chose it to direct attention to architecture oriented to society’s needs – and not to the wishes of wellheeled of investors. Regardless of what one thinks of the implementation of his ambitious concept, he deserves credit for addressing the profession’s real problems instead of simply allowing the same group of “stars” to cultivate their images. On display in the halls of the Arsenale and in the individual national pavilions are, primarily, modest projects that represent the normality achieved in efforts across the globe. Visitors also encounter topics such as do-it-yourself construction, locally sourced materials, simple structures and prefabrication – the same themes we cover in this edition of DETAIL on cost-effective building. Of course, affordable housing plays a decisive role: Heide Wessely’s article in the Discussion section looks into why it is so expensive in Germany (see p. 438ff.), while in Technology, Rainer Hofmann gives his insight into erecting it economically by describing four of his own residential projects (see p. 496ff.). In our Documentation section we present a shelter for the homeless in Ingolstadt, Germany, made of concrete sandwich panels; a school in Japan employing standardised timber; and a combined studio and residence in London in which the architect mixes a variety of especially low-priced materials. The example in London reminds us of the great potential of very simple, unconventional solutions.

Lucky Dwelling Heide Wessely

Housing costs have increased considerably in Germany. Especially in major cities and metropolitan areas, prices for purchasing homes and renting apartments have gone through the ceiling. Low interest rates, crashing stock markets and finance crises have prompted investors to move their capital to more tangible items: to concrete and bricks. Dwellings have become speculation objects. The free market regulates the price.

Exacerbating matters, the federal programme subsidising affordable housing in Germany has been under-funded for decades. In 2006 the federal government turned over the housing agenda to the states: this nearly brought the construction of social housing to a complete standstill.

But cities and communes also prefer to invest in infrastructure projects. On top of that, construction is more expensive than ever

1

before. In the year 2000, the cost per square metre for a unit in an apartment building was €2210. By 2014 it had risen to €3080.

So it’s no wonder that a deep chasm has opened up between supply and demand of affordable housing.

And then came the refugee crisis.

At the very latest, last summer when thousands of persons in need of protection reached Germany, it became clear that ­answers to the long-suppressed housing problem must be found – and quickly! At first, of course, a concerted effort was necessary just to get roofs over the refugees’ heads. But the new situation has finally forced us to focus on affordable housing – and this time we have to get past studies and discussions and act. Affluence is often accompanied by stolidity. This can be a wake-up call, a chance for Germany, for its

residents and for its building culture.

Cities, universities, local and federal governments, architects’ organizations, investors, etc. have heeded the call and are developing ideas to reduce the cost of housing. ­Discussions are taking place on a variety of levels: in politics, in sociology and in architecture. There is such a large number of proposals, approaches and demands that it is not possible to present them all in this article.

We can only report here on a fraction of these initiatives and touch on some of the pressing topics. But one of the most pertinent questions – the discussions always lead to it – is: What makes housing so expensive in the first place?

Location makes a difference The price of housing – and the percentage of income it consumes – varies from city to city. In Munich, Berlin and Hamburg, renters must now spend about half of their respective incomes on housing. In Saxony and Saxony Anhalt, the average percentage is still considerably less than the level generally agreed upon as acceptable: thirty per cent of one’s income.

As of April 2016, for new rental contracts, Munich heads the list with €20.48 per m2.

Over the last five years, prices have increased markedly – thirty per cent in Munich, twenty-four per cent in Stuttgart and thirty-two per cent in Berlin. But incomes are not keeping pace. So who can afford the available housing? How can a household with an average income (€2700 per month take-home pay) pay such a high sum for rent? Lawmakers are attempting to legislate affordable rents, but because of the numerous loopholes that still exist and the reluctance on the part of the renters to take action against landlords, these efforts haven’t had the desired impact. For many, the solution is to move to the periphery, with all of the associated problems: the long commute, traffic jams, the cost of gas, the accompanying CO2 emissions, and, last but not least, sprawl. And there is a shift in demographics. Persons with lower incomes

are moving to the periphery; this has an effect on city centres, which become places where only the affluent live. But the lack of affordable housing in attractive cities affects not only persons with low incomes and immigrants: it now also affects the ­middle class. Nonetheless, the apartment owners have no trouble finding takers. They also profit from the imbalance that exists with respect to earnings and accumulation of wealth – and the fact that there are plenty of people for whom money is simply not an issue.

present it is nearly 47 m2. This development is only partially explained by the growing number of one-person households and the users’ increased expectations. Another aspect is that the number of clients who can afford luxurious second residences in central locations has grown. The purchasers or renters are typically not from the neighbourhood: globalisation has also internationalised the real estate market.

Supply and demand now regulate the price, and demand is high. This is compounded by the fact that Germany’s federal government has almost completely withdrawn from housing. Its decision to successively sell all government-owned apartments (a total of 38600 units) fits in this pattern. There are now just 1.5 million social housing units in Germany.

On top of all that, one recent study by the

Taller, larger, more appealing vs. social housing And so it will come as no surprise that the average floor area per person continues to rise. In the years immediately following World War II, the average German had a surface area of 20 m2 available to him. By 1991 this number had risen to 35 m2, and at

IW Cologne found that fifty-four per cent of these units are occupied by persons who are not entitled to them. For this reason too, in recent decades, instead of providing social housing to those in need of it, the federal government has made housing allowances available. This initially seems to make sense, because households that no longer require the subsidy can remain in the same apartment. To try to convince them to leave is both legally and in humanistically problematic. But by subsidizing people instead of buildings, the government plays into the hand of the owners of the property: as long as supply is short, they can determine the rent prices at will.

The federal agency takes action Therefore, it was a major step in the right ­direction when in 2016 the federal housing

And in Japan, safety codes, such as railings, and technical requirements are much less stringent than in Germany.

Nevertheless, perhaps there is practicable middle ground. Which take us to another country, to Romania, where the construction standards are also considerably lower than in Germany. Do-it-yourself construction plays an important role, and one it willing to overlook the one or the other minor deficiency.

But in Romania it’s the percentage of condominiums and other forms of ownership that is noteworthy: it’s ninety-six per cent! At the tail end of the scale are Germany and Switzerland, where the percentages are just

11

fifty-three and forty-four per cent respectively. In these two countries, both standards and construction costs are high. But on top of that, Germany also invests in high standards in the protection of animals, nature and biodiversity. This privilege of the “first world” sometimes bears strange fruit – for example, when it is stipulated that a host of sparrows must be relocated – and the developer must pay the €40,000 tab.

Participation by individuals Germany is a democratic nation. Here the citizen’s voice (and vote) carries weight. For building projects, that often means that the person who wants to build must spend a

large amount of time convincing others. It ­also involves conflict and legal wrangling – all of which, especially when it comes to increasing density – impede the process.

But there must be a re-evaluation of the commonly held attitude that a building being erected close by constitutes a threat.

When private clients join together as a “building group’” to plan and erect an apartment building, they get to make the decisions themselves, for example, whether they want to share a terrace as a trade-off for more living space. And when they already are acquainted with their soon-to-be neighbours, sharing and “close quarters” are often no problem at all.

If I decide of my own accord that I’d rather use a bicycle and therefore do not want to invest in a parking garage, it’s a completely different situation from finding out that the complex I’m about to move into simply doesn’t have a parking garage.

There are lots of examples of successful projects; one is an apartment complex on Berlin’s Dennewitzstrasse (ill. 12) by a team of different architecture firms made up of Roedig Schop, sieglundalbert, and dmsw.

The site was affordable because it borders railway tracks. The low-budget project doesn’t look it at all: proud and powerful, it has a gleaming metal skin that cloaks individually designed units, and some of them are downright extravagant.

In conclusion, a few statistics Over the last fifteen years, the cost ratio of the building carcass to the fitting out has gone from 54:46 to 46:54 %. This is attributable to today’s higher technical standards and user demands, but also to more rigorous government regulations. According to a study by the federal real estate association (Bundesverband deutscher Wohnungs- und Immobilienunternehmen), since the year 2000, the cost to erect a new building has increased by forty per cent. Of that increase, about twenty-seven per cent is attributable to construction costs. The study determined that fire-safety and noise-abatement measures, as well as measures to safeguard against inclement weather and earthquake-safety measures, in combination with accessibility requirements and energyefficiency measures, were the cause of the increase.

The fulfilment of the energy-efficiency regulations alone made up 6.5 percent – although the most recent amendments (EnEV 2016) constitute only a negligible improvement. In this realm, the investment and the benefit had from it are out of balance. One is often astonished that such ordinances are put into effect. The EnEV is part of the German economic management law. Moreover, the EU, the federal government, the states and the municipalities are 12

responsible for different aspects of regulatory law. This leads to incompatible requirements – and lost time for those who must implement them.

A solution The task at hand is clear and many architects have been demanding action for some time now: clear jurisdiction and deregulation. There must again be room for new, alternative ideas, and that state will be much easier to achieve when the present constraints are loosened.

Here too policy makers must step up to the plate. In Germany, the Standards Committee is a privately run organization; a num-

ber of its members have ties to the construction industry. This gives rise to speculation that the one or the other norm is put into effect at the urging of someone employed in the very branch that will profit from it, and not with the best interest of the client and the occupants in mind.

Fortunately, the federal government has recognized this problem and is in the process of putting together a Standards Committee that is independent. The will is there among clients, lawmakers and architects to simplify things – to allow society to erect buildings more simply and economically. However, it takes courage to exercise that will.

The seaside town of Southend-on-sea, located near London and rich in tradition, b is a popular destination for city dwellers who are interested in a trip to the beach. It is best known for the world’s longest leisure pier, measuring more than two kilometres in length.

Slightly set apart from this coastal town’s hustle and bustle, the new beach huts are situated alongside a gravel beach. The site offers views of a defensive structure located further towards the east, a relic of the Cold War era that reaches deeply into the sea.

The colourful beach huts are the outcome of a competition held by the city. They are placed along an existing beach promenade made of concrete. People have been coming here for a swim since the 1980s.

The huts differ from their historic predecessors due to their slanted green roofs and asymmetrical floor plans. The angled arrangement of the facades facing the beach creates open spaces that are protected from wind, sun and the views of curious neighbours. When the large folding doors

a

are opened, ­exterior and interior spaces merge. Tenants also have the opportunity to customize their huts.

Simple and affordable construction materia als such as plywood and polycarbonate panels were combined with materials that are recycled or found on-site. Each exterior wall consists of conventional, load-bearing industrial pallets set in a timber frame. The structure is clad in polycarbonate panels on the exterior and plywood boards on the interior. The gap was filled with material reclaimed from the beach, and the pebbles, shells and crushed brick behind the polycarbonate panels give each hut a unique appearance. The reflecting colour scheme of each neighbouring hut enhances this effect. Storage mass and unique character are created in one go.

Roof and wood facades are prefabricated and were assembled on-site within a short period of time during the winter months.

Eight of the altogether 16 beach huts are currently occupied. The building permit has just been issued for the remaining huts.

He, She & It is a studio house in the garden of an existing residential building for two visual artists. Using simple construction methods and low-cost materials, architects Davidson Rafailidis from Buffalo have succeeded in creating an atmospheric gem.

The ensemble consists of three different volumes with varying spatial requirements, which are joined together to form a single structure. The building includes workspaces for a painter and a ceramicist/silversmith, as well as a greenhouse. Each of the rooms has its own specific atmosphere, which differs significantly from the mood of the

others. It reflects not only the respective use, but also describes the users‘ predilections.

‘He’ is an artist. His studio is a windowless ‘white Cube’, thereby maximising the wall surface area. Illumination is exclusively via a very long skylight, through which uniform, indirect natural daylight enters. She is a ceramicist and silversmith. Her studio is divided into a workshop for messy, wet ceramic work and a work area for delicate jewellery-making. The space has large window openings with scenic views and accentuated illumination, ranging from darker areas to brightly lit worktables. The walls and ceil-

ing are entirely clad in soaped maple, which gives off an intense smell of wood. It is a greenhouse consisting of seedlings in the spring and plants in the winter – clients with a very simple wish for maximum light and year-round above-freezing temperatures.

The polycarbonate shell is translucent, adding a zone of almost-outdoor space to the two other somewhat introverted work spaces, without any direct views but with the sounds and colours of the surrounding environment.

The spaces are grouped to form a cluster of three almost identical mono-pitched sheds.

connect, the walls are completely removed up to a height of 2.03 m. The remaining ridge wall segments above act as structural trusses to span the openings freely, so that the roof structure seems to float above the ground. Although He, She & It appear as independent, materially distinct volumes, structurally and climatically they depend on one another. The interpretation of the building fluctuates constantly between three independent parts and an interwoven wholeness. Folding walls at the open interfaces of the volumes allow users to divide the space into its three segments or to open it up completely. The climate conditioning strategy underscores the dynamic spatial experience

and the constant redefinition of space. Each of the three buildings has its own structure and different constructional properties. The insulated interior sliding-folding doors and exterior operable openings therefore have to be used to adapt the building to different weather conditions. This is contrary to common climate control practices, which seal the interior space as much as possible from the exterior and use mechanical services to create an artificial indoor climate in summer and winter. With He, She & It, the architects have opted for spatial rather than technical adaptation to the seasons. On cold and sunny winter days, for example, the slidingfolding partition walls are opened up to let

Care and attention

Panel systems perform by the sea and in the city

A high-performance, multi-coat render by Saint-Gobain Weber has been used as the exterior finish on a 60-bed dementia care home in Winnersh, Berkshire for Abbeyfield, a national charity providing sheltered housing and care homes. Intimate circular bedroom wings minimise corridors and lead to communal spaces to aid wayfinding and spatial recognition. The clover-leaf layout of the linked buildings was achieved using timber-frame construction, with much of the fabrication carried out off-site, including the curved outer skin formed by the render carrier board for the weber.rend MT system.

Metalline products were specified for the Sir Ben Ainslie Racing America’s Cup team base on Camber Quay in Portsmouth, designed by architects HGP. The building, with a BREEAM ‘Excellent’ rating, will house the team’s headquarters for design, training and boat building, together with a public visitor centre and VIP hospitality. Over 400 sq.m of superior grade J57S aluminium panels were fitted both internally and externally to the building envelope, and above the boat housing and hangar area a stacked floor appearance has been extenuated with curved and flat Ultima insulated panels in a natural silver-anodised finish.

lengths and joined together to form a 6,300 mm long aspect. The flat sandwich panels are finished in a grey Syntha Pulvin whereas the feature panels, complete with a 76 mm projection, are finished in green and white Syntha Pulvin.

The company’s glazed-in Ultima insulated panels have been chosen for the external facade of the recently refurbished council offices in Eastleigh, Hampshire. The dilapidated 1970s office block has been transformed into a BREEAM ‘Excellent’ building with a bright and airy interior and a distinctive exterior designed to create a landmark in the city centre.

The panels are described as extremely versatile and possessing excellent acoustic, thermal and fire performance ratings. They are typically produced from high-grade aluminium as well as from stainless steel or patterned copper and can be adapted to fit a variety of facade details. The panels can also be glazed into a standard curtain walling or, as in the Eastleigh project, a structural glazing system.

This method reduced time and cost early in the build programme, resulting in a cleaner and tidier site. The lightweight render system incorporates glass-fibre meshcloth reinforcement with a resin-rich adhesive coat that can carry a choice of finishes in a wide range of colours for a weatherproof, vapourpermeable protection. This system can also be applied to uneven masonry or mixed substrates where a high level of crack resistance is required. ¥ Saint-Gobain Weber United Kingdom � +44 (0)8703 330070 www.netweber.co.uk

Metalline panels, rainscreen facades, soffits, column covers and bespoke metalwork are all available in a range of colours and coatings, and the company states that, with the latest cutting, punching and bending machinery, it offers a valuable contribution towards making a feature of the external view of building designs.

Translucent cladding panels from Rodeca were specified for the £3.5 million National Training Academy for Rail developed in conjunction with Siemens’ Rail Division. A total of 575 m2 of PC 2540-7 lightweight wall panels feature on all elevations and the 40 mm-thick, 500 mm-wide panels have been used partly as rainscreen and partly as a double-wall construction.

The polycarbonate cladding has also been used on the £760 million Severnside Energy Recovery Centre project in South Gloucestershire. The 34 MW facility will produce enough electricity to power the equivalent of 50,000 homes and could also provide heat to local businesses in a solution which will enable the West London Waste Authority to divert 96 % of its waste from landfill, saving two million tonnes of CO2 over the duration of the 25-year contract.

Tata Steel has launched a colour system that is designed to easily and quickly navigate specifiers to the right Colorcoat® prefinished steel product and shade for any metal roofing or wall cladding project. The Colorcoat Compass digital system, claimed to be the first of its kind in the European building envelope market, allows almost any object to be scanned and the colour matched within seconds, including another building material or a client’s corporate colours, for example. It is available via the company’s building envelope representatives and key supply chain partners.

Around 4,000 m² of tongue-and-groove Opal panels in lengths of up to 13 m have been installed around the ground-floor process areas and the north-east gable end of the building, adjacent to Seabank Power Station and the former Terra Nitrogen plant, by specialist sub-contractor Massey Cladding Solutions for main contractor Sir Robert McAlpine. The majority of household residual waste will be delivered to the facility by rail from West London.

The system works alongside a specially developed colour measuring instrument to return a detailed colour scan and will show whether there is an exact match within the standard HPS200 Ultra and Prisma ranges, or a previously matched colour through the bespoke Repertoire® selection, as well as details of the available Confidex® guarantee based on building location, application and colour. It also features a useful RAL colour search function.

The new building uses single- and doublelayered sections in which certain areas will glow at night and the material also admits natural diffused light into the classrooms, main entrance foyer and main training hall during the day. Architects CMPG chose the fast-track tongue-and-groove panels to meet the brief for a modern learning environment with lots of natural daylight, to provide a backdrop for students that influences their understanding of engineering education, as the building structure can be seen through the cladding.

The Rodeca Deco-Color panels (where the exterior layer is coloured differently from the interior layers, for extra effect) have been used with one outer wall in Kristall colour and six rear walls in Opal, allowing light transmittance of up to 41 %. The panels are claimed to be two hundred times tougher

than glass and are capable of delivering U-values of 1.00 to 1.10 W/m²K.

Changing spaces is becoming automatic

Bespoke solution

The first Dorma Magic Glass partitioning wall in the UK has recently been installed.

This ‘transparent to opaque’ solution retains all the benefits of an acoustic, glass dividing wall. It features liquid crystals suspended in a conductive layer: as soon as an electric current is passed through it, the crystals rearrange in tight formation to create clear glass partitioning. At the flick of the wallmounted or remote-control switch it again becomes opaque, so giving privacy when required. Combined with 50 dB Rw acoustic performance, this solution extends the applications for movable walls.

The renovation of the office and conference floor of DVB Bank in the City-Haus building in Frankfurt, Germany features customised lighting by Zumtobel. One of the earliest Frankfurt skyscrapers to have a column-free facade structure, the unusual axis dimensions and reduced installation depth placed special requirements on various features of the project. The 40th floor is dominated by glass and a mix of white and grey tones, and the lighting had to integrate seamlessly into the design of the offices, conference rooms and a coffee bar, providing an open and welcoming appearance.

Said Julian Sargent, group md of sole UK distributor Style, “Magic Glass is a superb new addition to the wide-ranging benefits of the Dorma Moveo system. This is an extremely exciting development and we’re expecting huge demand from a diverse cross section of sectors including healthcare, education, hospitality and corporate.”

Also in the Dorma Moveo range, the ComfortDrive movable wall system (above) has been used to divide office space in Boston Consulting Group’s Knowledge and Analytics centre in London’s Canary Wharf. A fully automatic solution, the fabric-finished panels slide easily into place to rapidly create a

solid divide, and offer 55 dB acoustics for privacy between the two areas. The system was chosen to add flexibility to the main meeting room.

Style says it is seeing a significant growth in specifications for fully automatic partitioning walls, the speed and flexibility allowing room configurations to be changed numerous times a day if required. ComfortDrive automation is computer controlled, so all seals will automatically extend or retract to the appropriate point, through each stage of the operating cycle, avoiding potential damage by mishandling of the panels. A network of sophisticated sensors ensures an instant response if an obstacle is encountered.

A very adaptable design, the Moveo system is available in a wide range of finishes from laminate through to polished wood veneers.

Additional features include acoustic sound absorption boards, magnetic display boards and dry-wipe marker and projection surfaces; single or double inset pass doors can be included for ease of access.

A special luminaire was developed based on the recessed version of MIREL Evolution, its neutral white light enhancing the purist design of this area. Arranged in groupings that blend into the office architecture, they define the spaces and deliver task-specific lighting for deskwork, meetings and presentations. Individual LED modules enable different-sized products to be created using this modified form, offering flexibility for a variety of functions.

‘The Designers Guide to Structural Timber Frame Fire Safety During Construction’ is an online video issued by the Structural Timber Association (STA), which enables architects, design and build managers and project architects to be aware of potential fire risks during the construction phase of such properties, and the key ways that these risks can be mitigated.

Smart Buildings 2016, the UK event dedicated to integrated building technology, takes place from 18 –20 October at the Birmingham NEC, once again forming part of the line-up at UK Construction Week, which comprises a total of nine specialist shows of interest to architects, specifiers and design professionals.

Funded by a CITB bid and produced with input from the HSE, the video succeeds the STA’s previous fire safety CPD, bringing legislation up to date and, although focused on structural timber frame construction sites specifically, many of the practices and legislation requirements are applicable across other forms of construction.

Andrew Carpenter, chief executive of the STA, commented, “Following the high-profile court case where the HSE fined an architects practice for not following the STA fire safety guidance, or undertaking an independent assessment, the HSE stated that ignorance of guidance is not an acceptable excuse and that design groups should obtain suitable training.

“In an effort to ensure that architects and site managers comply with relevant legislation, such as CDM 2015 and HSG 168, we’ve updated our guidance into an easily accessible online video. Raising the bar with regards to best practice standards, the video will enable construction professionals to comply with HSE requirements.”

This is further supported with advice note documents and the STA’s existing fire safety materials, such as ‘16 Steps to Fire Safety’.

Throughout the video pause points are provided which allow the viewer to reference the written documents to gain a complete overview of the factors to be aware of. ¥ www.structuraltimber.co.uk/informationcentre/video-vault

Leading industry bodies supporting Smart Buildings 2016 include the KNX Association, the Chartered Institute of Architectural Technologists, the Electrical Contractors Association and the British Institute of Facilities Management. Showcasing the latest innovations in smart building technology, the event caters for professionals across the full spectrum from home automation, climate control and lighting to access and security, workplace technology, entertainment systems and the Internet of Things.

Central to the 1,000 sq.m plus of floor space will be the Smart Buildings Hub, which will host pioneering seminars, CPDs, debates and workshops; the Hub will also be an exemplar building structure exhibiting the latest smart products and technologies.

New this year is a dedicated Workplace Zone. This space allows companies cater-

ing specifically for the smart technology market in commercial applications, such as Framery (below, left) to showcase products like connected furniture, AV systems, conference technology and virtual workplaces.

Motion detection technology is becoming an important aspect of collecting and exploring data on building occupants and behaviours, and visitors to the Theben stand will be able to examine its ranges of presence and motion detectors, along with other building control systems and accessories.

Home automation specialist Savant will be exhibiting its range of connected home technology and launching the new Savant Remote (below, right) and Savant Pro app.

From adjusting lighting to controlling entertainment, the company’s products are said to offer the ultimate in whole-home automation, creating a more interconnected and responsive environment.

Other exhibitors will include the pro-audio and commercial sound equipment provider Audiologic, manufacturer of building automation and control technology HDL Technology and smart security specialist Armco Key Security. ¥ www.smartbuildingslive.co.uk

Windows on to the world of security

Amongst the latest developments from lighting components and electronics supplier Fulham are the WorkHorse LED family of programmable drivers and the HotSpot Plus LED driver and emergency system. The WorkHorse drivers can replace numerous variations of fixed output drivers and are a smart solution for greater LED efficiency, says the company. Programmable features include output current, dimming curve and lowest dimming percentage, allowing the driver to match the output of existing fixtures or serve as a flexible platform for new luminaire designs.

Curtain walling by Kawneer completely wraps a new judiciary building that is as stunning as it is secure, says the company.

Its AA®100 zone-drained curtain walling, with 50 mm sightlines, horizontal face caps and gaskets to vertical glass and glass joints at mullion locations, has been used on all elevations of the £14 million Aberdeen Criminal Justice Centre. This is complemented by thermally enhanced top-hung casement windows as inserts on the south and west elevations, AA110 dry slope rooflights with 65 mm sightlines and series 190 heavy-duty commercial entrance doors.

Fulham’s intuitive SmartSet programming platform enables powerful capabilities via a hand-held controller or PC software. Four models are available in 40 and 60 W versions with different case size and termination options, in dimming and DALI dimming model types. They can dim to 1 % of programmed current and have one-touch programming for high-volume usage.

Designed by Ryder Architecture, the 4,518 m2 building for Police Scotland via North Hub Scotland comprises a 60-cell custody facility with offices and virtual courts for the criminal justice department and space for an integrated local policing team. The custody facility is placed on a precast concrete plinth merging with the landscape (former railway sidings), whilst the office space and police team are located in the steel-framed pavilion above � the element wrapped in the curtain walling.

HotSpot Plus also makes use of SmartSet and combines a dimmable LED driver, an emergency LED driver and a replaceable battery, eliminating the need for separate emergency systems. Under normal conditions it functions as a dimmable 40 W constant current LED driver with a programmable output current range of 250 to 1,400 mA. During a power outage the system automatically engages an integrated back-up battery which can provide 5 W of power for 180 minutes or 10 W for 90 minutes.

Fulham Group has transferred its European head office to Alkmaar in the Netherlands, following the recent acquisition of Lumotech’s LED driver business, which is based in that city. ¥ Fulham Company Inc. The Netherlands � +31 (0)72 572 3000 www.fulham.com

Ryder architectural director Chris Malcolm said: “The Kawneer systems play a significant part in the project as we needed to have a very clean glazed facade. Aluminium is recognised as a standard acceptable finish in terms of sustainability but the SG system allowed us to express the horizontality of the facade. The glazed elements were integral to the concept of a solid base below and lightweight transparent pavilion above.

The Kawneer systems interface simply but well with the other materials used on the project. The curtain walling is continuous around all four sides of the building so is held between the concrete panels underneath and the roof plane above.”

Kawneer has joined forces with GEZE UK to launch an automated ventilation solution for all types of projects. The AA720 parallel-

opening window now combines with the GEZE Slimchain window drive system to provide effective ventilation around the entire window perimeter without detriment to safety and security for residential, healthcare, education, commercial, retail and leisure sectors.

The new CE-marked, assisted-opening system has been fully tested to the PAS 24:2012 enhanced security performance standard as well as BS 6375: Part 1 (weather) and Part 2 (strength). A versatile system for new-build and refurb projects, as Slimchain can be used on windows up to 400 kg, its intelligent electronics allow continuously adjustable drive strokes and individual speeds. ¥ Kawneer UK, United Kingdom � +44 (0)1928 502500 www.kawneer.co.uk

Originally built over 200 years ago, the now revamped Spitfire Studios building in London’s King’s Cross combines commercial office space with eight residential apartments. The redesign incorporates modern features whilst preserving the rustic interior, including large areas of exposed brickwork.

The development’s mixed use called for a high level of security, with a separation of the residential and commercial areas.

Wayfinders using the latest touch technology from Zytronic have been installed at Asia’s Marina Bay Sands resort. The company was commissioned by digital wayfinding specialist Abuzz to deliver its PCT™ Projected Capacitive Technology touch sensor assemblies for this prestigious business, leisure and entertainment project in Singapore, in the heart of the central business district. It features large and flexible convention and exhibition facilities, 2,560 hotel rooms and suites, what is described as the best shopping mall in Asia, celebrity chef restaurants and an outdoor event plaza.

Kingspan Insulation’s fire safety technical bulletin focuses on buildings with habitable storeys 18 m or more above ground level. It includes a general overview of the linear, performance-based and fire safety engineering routes, to check if a desired buildup follows the best route to compliance, along with recent case studies and latest build-ups successfully tested to BS 8414–1: 2002 and BS 8414–2: 2005, in accordance with performance criteria set out in BR 135.

Specialist company Allgood Trio designed and installed an advanced security and access control package, including a proximitybased access system to the platform lift and external and internal doors. This is complemented by stylish audio/video entry systems comprising grade 316 stainless-steel panels and flush, wide-screen video monitors communicating with commercial and residential spaces. Discreet underfloor automatic door operators control the main entrance and lobby doors, and high-definition CCTV cameras in and around the building allow remote viewing of live and recorded footage of the entire facility. ¥ Allgood Trio United Kingdom � +44 (0)1708 345067 www.allgood.co.uk

Abuzz was invited to develop and implement 29 new wayfinding points, and the solution includes its Landmark touch screen directory customised to meet the client’s brief. The landscape unit maximises customers’ line of sight, allowing them to easily orient themselves. Zytronic 40 in. landscape screens driven by compact ZXY110 touch controllers, offered with native Windows device drivers, were specified to provide the best possible user experience. ¥ Zytronic United Kingdom � +44 (0)191 414 5511 www.zytronic.co.uk

Top test rating Class 1 classification for BS 476: Part 7: 1997 Method for Classification of the Surface Spread of Flame of Products has been awarded to ANS Global for its living wall modules. A variety of plants were tested in their containers to a total weight of 7 kg to see how quickly fire spread across the surface, by measuring the lateral spread of flame along the surface of a specimen living wall module whilst in a vertical position. ¥ ANS Global � +44 (0)1243 545818 www.ansgroupglobal.com

DETAIL Prize 2016 – winning projects and the start of reader voting The jury has chosen the three winners of the DETAIL Prize 2016 and the DETAIL structure and DETAIL inside special prizes. The main prize goes to Sean Godsell Architects for the MPavilion project (pic. 1) in Queen Victoria Gardens in Melbourne, Australia.

The temporary pavilion was used for cultural events and was freely accessible. Thanks to a facade that could be flexibly opened, light and shadow inside the building could be adapted at will. During the night, the pavilion could also be securely locked. The structure special prize structure has been won by Knight Architects for their moving

footbridge Merchant Square Footbridge (pic. 2) in London. With its five fingers, the bridge spans the 20 metre-width of the Grand Union Canal, and using hydraulic jacks can be pulled up like a fan. The bridge is accordingly also an architectural sculpture. The inside special prize goes to Japan: With K8, Florian Bush Architects have created a small spatial wonder within the bustling nightlife district of Pontocho in Kyoto (pic. 3). The building houses a bar and gallery that extend across eight levels.

Not yet decided, however, is the DETAIL Readers‘ Prize. From 1 to 14 September
