Foto de stock - 27 August 2019, Austria, Wien: The new ""Hoho Wien"", a high-rise consisting of 75 percent wood from the first floor upwards, is located in the seaside town in the northeast of the Austrian capital. The special is not visible from the outside. With its slabs, the facade of the high-rise building in Vienna looks rather conventional. But about 800 wooden columns made of Austrian spruce carry the floors, the wall elements are made of the renewable raw material and also the wood composite ceiling. With an area of almost 20,000 square metres, it is a wood-reinforced concrete hybrid house that is unparalleled in this dimension, according to master builder, engineer and project developer Palfy.
