Innovative rooftop made of modular timber homes proposed for Berlin's complex

Architect Sigurd Larsen and his team took part in the City Above the City architecture design competition organised by Metsä Wood in 2016. Their project "Dachkiez, Village on the Roof," was one of the winners in the competition. This year, the project and the architect were invited to the Venice Biennale.

The Venice Biennale of Architecture is globally one of the biggest exhibitions for architecture. The event takes place every other year, and this year it lasts from 26 May until 25 November. The main architecture exhibition takes place at 30 pavilions in the Venice Giardini, many of them designed by the biggest names in architecture, like Carlo Scarpa and Alvar Aalto.

 

City Above the City competition

Metsä Wood's competition inspired architects worldwide to design wooden extensions to go on top of existing buildings in city centres. Some 170 entries from 40 countries proposed wooden solutions to the challenges of urbanisation. The idea was to show how wooden materials, like Kerto® LVL (laminated veneer lumber) can make construction fast, light and green.

Sigurd Larsen together with Simon Jendreizig, Vanessa Panagiotopoulou, Marlene Kjeldsen, Guillermo Fernandez Villar and Pedro Campos Altozano designed a project called "Dachkiez, Village on the Roof" for the competition. A massive, 270-metre-long concrete block in Berlin was selected as the building plot for the design. The building is located at Heinrich-Heine-Straße between the attractive Kreuzberg and Mitte neighbourhoods.

In Dachkiez, the extension on top of the building is designed to use a flexible, wooden, modular system. The basic module is an apartment suitable for singles or couples. The basic unit can be extended with one or two plug-in modules, which can include additional bedrooms and an extension to the bathroom. The design also includes common areas like a green park on the rooftop. Each unit has big windows with a view of the Berlin skyline.

"This entry was both believable and utterly relevant to its social and urban context. It's entirely possible to construct and adds a further layer of landscape to the city," commented competition jury member Mike Kane, Senior Lecturer in Architecture at London South Bank University.

 

Sigurd Larsen design & architecture studio

Sigurd Larsen is a Danish architect based in Berlin and working in the fields of architecture and furniture design. He uses wood as the main material in the majority of his work. "The haptic of the material, the endless possibilities and the many positive attributes regarding sustainability make it a convincing choice," says Larsen.

Larsen founded his own design studio in 2009. This is his first invitation to the Biennale. "I was very excited about the invitation. We had a lot of great feedback from visitors. Several journalists described the Dachkiez project under the topic of wood construction, densification of inner cities and housing shortage."

CTI warns against indiscriminate ban of combustible cladding on high rises

The Confederation of Timber Industries (CTI) has recently responded to the Government's proposal on banning the use of combustible materials in cladding systems on high-rise residential buildings.

The CTI's official response - downloadable here - focuses on the "ambiguity over the scope of the ban being proposed in the consultation." 

"While we applaud the findings of the Hackitt review, and can fully understand the Government’s desire to be seen to be taking tough action, an outright ban on certain materials is likely to have unintended consequences," explains CTI Director David Hopkins.

"One particular area of concern is in the consultation proposal to ban the use of combustible materials throughout the entire height of walls in buildings over 18 metres. There is a large market for timber cladding and fascias on the first three stories of such buildings. This is within easy reach of regular fire inspection and maintenance regimes. Yet this market would be lost if the proposed ban goes ahead as described in the consultation."

Major trade organisations such as WPA, TRADA, STA, BWF and TTF are currently working together on fire guidance and safety across all points of the Timber Supply Chain.

"Timber has a large role to play in fire-safe, sustainable construction. We need to be pro-active to maintain this," concludes Mr Hopkins.

Treated construction timber no threat to indoor air quality, says BRE review

Preservative treated timber is present in a range of construction products in our homes, including parts of the structural timber frame, window frames, tiling battens and in the roof structure. 

In mid-2017, the Wood Protection Association (WPA) commissioned the Building Research Establishment (BRE) to help understand how treated timber performs in the context of air quality within buildings.

The review considered industrially pre-treated wood products that have been impregnated with a wood preservative formulation in the context of a 2017 new build UK domestic construction.

BRE's research concluded that "the available scientific evidence suggests that emissions from preservative treated wood articles to air are small and further to that the complexity of the pathway from air within the building envelope/cavity to the indoor air compartment means that the concentration reaching indoor air is negligible. Thus, the evidence indicates preservative treated wood poses no threat to indoor air quality."

Since the BRE recommends considering further research and testing to add to the existing knowledge, the WPA has already made it known that more specific studies on the subject will be carried out.

BMBI Q2/2018: Sales of Timber and Joinery products up 9.5% against 2017

Sales through UK builders merchants bounced back in Q2 2018, with the BMF’s Builders Merchants Building Index (BMBI) reporting 7.2% growth in sales value over Q2 2017. There was one more trading day during Q2 this year, adjusting for this the average daily sales growth year on year was 5.5%. The strong performance in Q2 contrasts markedly to a weather-hindered performance in the first quarter of the year.

The Timber and Joinery category had a major impact on total sales value growth in Q2, up 9.5% year on year. Within this the Sheet Materials sub category was a big contributor.

Heavy Building Materials, the largest product category, also showed strong growth in Q2 2018, up 6.3% on the same period last year.

Looking at the year to date, which takes into account two very different quarters of construction activity, total builders merchants sales in the first six months of 2018 increased by 4.0% over the same six months in 2017.

The BMBI uses GfK’s point of sale tracking data drawn from over 80% of builders merchants’ sales throughout the country, making it the most reliable source of data for the sector.  The full Q2 report can be downloaded at www.bmbi.co.uk

Commenting on the figures, John Newcomb, BMF CEO said: “For the second quarter running the impact of the weather on construction output – and builders merchants sales – is clear to see. The warm, dry weather through much of Q2 has enabled construction work to catch up on sites that had stalled earlier in the year.  The merchant industry will be buoyed by Q2 sales and, with above average temperatures forecast into the autumn, we remain confident of continued growth this year.” 

Richard Frankcom, Client Insight Director at GfK said: “Following the dramatic weather in Q1 delaying the usual end of quarter external work kick off, we had been expecting a strong Q2 performance, and these results did not disappoint. Midway through April the weather improved and May and June delivered strong growth in almost every category. That said, price inflation and one extra trading day in Q2 2018 over the same period in 2017 also had an effect on growth, but we should be content that the builders merchant sector remains in good health.”
