Short construction time, competitiveness and an ecological image have increased the competitiveness and popularity of wood construction in Austria. The use of prefabricated CLT (cross-laminated timber) boards in particular is on the increase in the construction of apartment blocks, daycare centres, care homes and shopping centres. In the centre of the city of Graz, a 12-storey apartment block containing 143 apartments is being completed. - In the beginning, the buildings were designed for concrete construction but, as an investor, we wanted a new alternative and image. In order to achieve this, we started using wood, says Martin Partoll, Managing Director of the Aktiv Klimahaus company.
