Text description provided by the architects. Kajstaden - Tall Timber Building is an important landmark for sustainable construction and a reference project that shows that conversion to climate-conscious architecture is possible. Through research projects and several active wood projects, C.F. Møller Architects has focused on innovation as well as developing and implementing multi-storey buildings with solid wood frames. In Kajstaden, an active decision was made to prioritise industrial timber techniques for the building material to influence and take responsibility for the impact of the construction industry on the environment and climate change. A crucial advantage of wood, unlike other building materials, is that the production chain for the material produces a limited amount of carbon dioxide emissions. Instead, it is part of a closed cycle, where carbon is retained in the frame of the building.
Research also shows that buildings with a wooden frame make a positive contribution to human health and well-being- thanks to better air quality and acoustic qualities.
The Kajstaden - Tall Timber Building is nine floors high with an elevated ground floor and a top floor with a double-height ceiling. The high precision technology involved in CNC-milled solid timber with glulam elements results in air-tight and energy-efficient houses without other unnecessary materials in the walls. The low weight of the material means fewer deliveries to the construction site and a more efficient, safer and quieter working environment during construction. It took an average of three days per floor for three craftsmen to raise the frame. Mechanical joints with screws have been used, which means that the building can be taken apart so that the materials can be recycled. The total carbon dioxide saving is estimated to be 550 tonnes of CO2 when using solid wood instead of concrete.
Kajstaden is a central residential neighborhood near the water in the Öster Mälarstrand area of Västerås. The new neighbourhood is designed as a city block and is a natural extension of Västerås city centre.
The area includes Mälarparken and Notuddsparken, which link together to form a cohesive green area. The neighborhood has a generous view of Lake Mälaren and is located directly adjacent to the square and the quayside promenade. The concept includes an electric boat sharing scheme and a special chilled room in the lobby for food deliveries from MatHem.
