In the second part of our series, we visit the "Wall House" in a rural suburb of Santiago de Chile. The first project by the German architecture team F.A.R caused an absolute sensation in 2007. The residence, with its translucent membrane, looks like a Bedouin tent. Its success earned F.A.R new international commissions as well as the prestigious Architectural Review Award in 2007. ARTS.21 catches up with the talented duo in Chile.
