EL PATIInspired by the traditional courtyard building type, the concept aims to create a building envelope, that can be adapted to local needs with varying floorplan layouts. While providing housing on the upper levels, the ground floor with its green center courtyard offers commercial and recreational space to support the local community and spark the creation of small scale businesses. At night, the doors close and the building transforms into a private shelter, protecting the resi-dents against influences from outside.

The building can be constructed using recycled materials from the ruins (bricks, crushed and sorted rubble as concrete aggregate, refurbished corrugated metal etc. ), employing local knowledge and labor. To overcome the poor thermal prop-erties of the concrete and brick structure, the outside hull is wrapped in a simply constructed envelope of recycled cellu-lose insulation¹ behind a vented curtain facade. This prevents the structure from overheating and provides natural venti-lation. The sliding panels can be opened and closed to maximize the protective/ventilation effect.

The building works as an isolated structure, but could also be part of an extended network of courtyards that stretches over a whole city block, as a new interpretation of the traditional underground markets and passages.
