The Silicon House by architects Selgas Cano is deceptively urban. Both surrounded by and covered in trees and plant life, you would be forgiven for thinking it was a stylish country retreat. Yet aerial pictures reveal that the house resides in a (albeit quieter) neighbourhood in the Spanish capital of Madrid. Through several sleights of hand the architects have shown the potential for the home to be a space of complete privacy and calm, even in an avowedly urban setting.
