HasleTre is a 3000 sqm Office building in natural materials. It is planned as a wooden construction from the first sketch. The façade will consist of chipboard cladding and the idea is that the façade will change expression according to the seasons. Parts of the façade are covered with green plants that work in the Nordic climate, and we have planned a spectacular roof garden which is both a biotope for cultivation and a nice place to stay. The construction consists of wood from the inside to the outside and is planned as a dismantled and reusable building set.
