Openable concrete panels and sun-shading blinds add dynamism to the otherwise austere facades of the Elcano housing block by Madrid-based practice FRPO.
The block, which contains 13 apartments, has been built close to the centre of Madrid between two distinct areas. To the north, the main facade faces a busy road and a series of industrial buildings, and to the south, balconies now overlook a quiet garden space and pool.
