In Sweden, the trend towards ever-higher buildings erected in timber started at the end of the 1990s, when the parliament repealed a century-old law that had prevented the construction of wooden houses higher than two storeys. The latest examples of this new trend are two residential buildings by Swedish architects, Wingårdhs, in Sundbyberg outside of Stockholm. The houses, which contain just over 30 residential units each, are located on the shores of Lake Bällstaviken.
The use of timber also extends to the load-bearing construction, with walls made of cross-laminated timber (with some steel columns interspersed to manage larger spans), and insulated on the outside with 21 cm of mineral wool. With the exception of the entrance areas at ground floor, the walls had to be clad with plasterboard on the inside for fire safety reasons, whilst all apartments are equipped with sprinklers.
