Architecture firms 3XN and IttenBrechbühl have won an international competition with their design for the Tilia Tower©, an 85-meter-tall timber high-rise that will serve as a beacon for sustainability and an anchor for the up-and-coming district of Prilly-Malley. In addition to an ambitious wooden building, the pair of architecture firms will also oversee the energy-efficient renovation of two existing buildings for the real estate company Insula SA.
