Desert Atrium

A cultural centre carved into sandstone cliffs, organised around a central open-air atrium that channels cool air through passive ventilation. Rammed-earth walls and deep overhangs keep interior temperatures stable without mechanical cooling. The building disappears into the landscape — from the valley floor, only the atrium opening is visible.

The rammed-earth walls are built from material excavated on site, mixed with 5% cement and compressed in 150-millimetre lifts. Each lift line is visible as a horizontal striation in the finished surface, recording the construction process in the architecture itself. The walls are 600 millimetres thick and provide a thermal lag of 10 hours — heat absorbed during the day reaches the interior well after sunset.

The atrium works as a thermal chimney. As the sun heats the sandstone walls during the day, hot air rises through the 18-metre-tall void and draws cool air from underground channels at the base. Temperature measurements show a consistent 12-degree difference between the atrium floor and the surrounding desert surface. No fans, no compressors, no electricity.

The programme includes a 200-seat auditorium, three exhibition galleries, a library, and artists' residency studios. The auditorium is carved entirely from the cliff face, with acoustic panels made from local palm fibre. All water is harvested from fog nets strung between the cliff tops, collected in underground cisterns, and circulated through a greywater recycling system.
