HAUT is a prototype for building innovative and environmentally-friendly high-rise timber structures. The team – Team V Architecture, Lingotto, Arup and JP van Eesteren - built an ambitious sustainable building: a timber skyscraper, with 21 floors one of the tallest timber towers in the world. Never before has this highest sustainability rating - BREEAM Outstanding - been awarded to a residential building in the Netherlands. As a result of the new techniques for a timber hybrid tower of 73 meters high, there is globally interest for this combination of sustainability and urban densification.
