Project Size: 3,230 square feet

Program: The client, a businessman with a young family, wanted to experiment with unusual construction methods for his new house on a steep hill overlooking the sea and mountains outside Barcelona. He had three requests—large windows to take advantage of views, privacy from the neighbors, and the use of a new concrete technology that, if successful, could be marketed and used in future projects. The businessman commissioned Cadaval & Solà-Morales because of the firm's past work with concrete for the TDA House in Mexico (2006).
