News: Scandinavian firm CF Møller has revealed proposals that could see the world's tallest timber-framed building constructed in Stockholm.
As one of three shortlisted proposals in a housing design competition, the 34-storey Wooden Skyscraper is presented by architect CF Møller, architect Dinell Johansson and consultant Tyréns as a vision of future housing that would be cheaper, easier and more sustainable than typical steel and concrete constructions.
"The main reason it hasn't been done before is that concrete and steel have a big part of the market," CF Møller architect Ola Jonsson told Dezeen. "But now the building industry has started taking responsibility for the environment."
He continued: "Construction accounts for around 30-40 percent of CO2 produced in the world globally and if you look at the CO2 released in the production of wood it is a lot better than steel or concrete."
According to Jonsson, using wood could even be a cheaper alternative, as it is a lighter material that costs far less to transport. It is also more fire-resistant than steel or concrete.
"We have a long history of building wooden structures in Sweden," he explains. "We have a higher knowledge of how to use the wood those days and we know that glued or nailed wood does have very strong construction qualities."
If built, the 34-storey building would exceed the height of the nine-storey Murray Grove tower in London, as well as a proposed 20-storey tower in Vancouver by architect Michael Green and a Swedish tower approved at 30 floors. "I've seen sketches of other buildings, but we are definitely at the highest end of this discussion," said Jonsson.
Wooden pillars, beams, walls, ceilings and window frames will all be visible through the building's glass facade. The presented designs also include a concrete core, although Jonsson says this could be replaced with wood. "We believe a modern building should use every material for its best purpose," he adds.
The winning entry in the competition, organised by Swedish building society HSB Stockholm, is scheduled to open in 2023 to coincide with the organisation's 100th birthday. Anyone can vote for the winner using the HSB Stockholm Facebook page.
Other projects by CF Møller include an art and craft museum completed recently in Norway and a centre for entrepreneurs with a green fibre-cement staircase.
Here's some more information from CF Møller:
For HSB Stockholm's architectural competition 2023, three teams of architects have produced innovative proposals for private residences of the future at three different locations in the centre of Stockholm. Berg | C.F. Møller's proposed design is a 34-storey skyscraper made of wood.
Berg | C.F. Møller Architects are working in partnership with architects Dinell Johansson and consultants Tyréns on their entry. The team has chosen to build upwards, and has designed a 34-storey residential building, which will be seen for miles.
The building will be built over a wooden construction with a concrete core, and it is intended to give the people of Stockholm a new and characteristic beacon and meeting place in their city.
Back to basics
Wood is one of nature's most innovative building materials: the production has no waste products and it binds CO2. Wood has low weight, but is a very strong load-bearing structure compared to its lightness.
Wood is also more fire resistant than both steel and concrete. This is due to 15% of wood mass being water, which will evaporate before the wood actually burns. In addition, logs get charred which protects the core.
Wood secures a good indoor climate, perfect acoustics, helps regulating the inside temperature and can be exposed without being covered with plaster or other costly materials.
In Berg | C.F. Møller's wooden skyscraper, the pillars and beams are made of solid wood. Inside the apartments, all the walls, ceilings and window frames are made of wood as well and will be visible from the exterior through the large windows.
Social and environmental sustainability is integrated into the project. Each apartment will have an energy-saving, glass-covered veranda, while the building itself will be powered by solar panels on the roof. At street level there is a café and childcare facility. In a new community centre, local people will be able to enjoy the benefits of a market square, fitness centre and bicycle storage room. A communal winter garden will provide residents with an opportunity to have allotment gardens.
All three design proposals are available on HSB Stockholm's Facebook page. Here you can vote for your favourite and thus play your part in determining how private homes in Stockholm will look in the future.
About the competition
HSB Stockholm - Sweden's largest building society - is 100 years old in 2023. At that time an ultra-modern residential high-rise building will be completed in Stockholm city. Three architectural teams are now preparing the competitive proposals for the spectacular house that will be placed at one of three different sites in Stockholm.
Berg | C.F. Møller Architects is working together with architects Dinell Johansson and the urban planning consultancy Tyréns. The other two competing teams are Equator Stockholm with Mojang (Minecraft) and Utopia Architects with Rosenberg Architects.
