Located in a new area of expansion in Orio, just north of the Cantabrian motorway that connected San Sebastian to Bilbao, the Auditorium and Cultural Facilities Proposal by SOMOS Arquitectos won the first prize in an open competition. Taking advantage of the freedom regarding the position of the building according to the open regulations, they wanted to develop and fix their proposal based on three key decisions: built volume integration, the connection between urban plaza and marina, and an open independent structure. More images and architects’ description after the break.
