Structural Shade

Cantilevers in maritime light

Continuous eighteen-foot post-tensioned concrete cantilevers shield the south and west elevations from intense subtropical exposure. The geometry generates passive convective airflow across zero-threshold pocketing glass, tempering interior galleries without reliance on constant mechanical cooling.

Concealed motorized bronze louvers modulate afternoon salt glare, throwing disciplined linear shadow patterns across honed Roman travertine floor slabs and sheltered outdoor lounges.
