C.F. Møller Architects is behind Sweden's tallest timber building, situated in the Kajstaden district of Västerås, an hour's drive from Stockholm, with beautiful views of Lake Mälaren. Kajstaden Tower is 8.5 stories high, with an elevated ground floor and a double height top floor. All parts of the building, i.e. walls, beams, balconies, lifts and stairwells, are made of cross-laminated timber.
The edifice in Kajstaden features four flats on each floor, and each floor has taken four craftsmen an average of three days to put together. Mechanical joints and screws have been used, which means that the building can later be taken apart and the materials can be reused.
According to C.F Møller Architects, timber construction means sustainability. In recent years, the Scandinavian-based architectural company has focused on the use of timber in construction, as this can create huge CO2 savings. Buildings made of timber have a positive effect on the indoor climate and the people living in the buildings and have very low energy and carbon footprints.
C.F. Møller Architects is currently engaged in construction projects with a focus on the use of solid timber in Sweden and the UK. The practice hopes to be able to help push the construction industry in a more sustainable direction by realizing these projects as good examples and sharing its knowledge of building with timber, which has a number of advantages, such as the fact that it is a renewable raw material. Use of CNC-milled solid timber and glulam constitutes a high-precision technology and provides an airtight – and thus energy-efficient – building without adding other materials to the walls. The low weight of timber also means fewer deliveries to the construction site and thus a safer, quieter and more efficient working environment during construction.
