123 Social Green Housing in Madrid by SOMOS.arquitectos
The building’s exterior is clad in plastic panels (polycarbonate panels) on aluminium frames, in three shades of green. (sustainable and recyclable skin)
Instead of the common window roll-up blind, we have designed specific shutters for the project. Three-hundred and sixty-nine openings fixed through six different types. They open outwards and fold until they rest perpendicular to the facade. They have been made in aluminium and finished with the same open celled polycarbonate panels used in the facade.
