Reaching 24 storeys or 84 m, the world tallest hybrid timber tower is nearing completion. When complete it will house a hotel, apartments, a restaurant, a wellness centre and offices. Constructed with a concrete core, the majority of the volume of the buildings is made up of self-supporting prefabricated timber elements including the exterior wall, floor and columns. The floor system is made up from a composite CLT and concrete, again wholly prefabricated. A small concrete ring beam at the exterior wall and floor interface ties all of the elements together. Construction of the timber components is on a four day per storey cycle. According to Rüdiger Lainer and Partner, the project’s architects, the twin tower project has 76 per cent of the structure made from timber elements.
