Social housing for IBAVI on a plot where a school of sandstone walls had stood and had to be demolished. The project's strategy is material recycling: the rubble feeds the new construction. 140 m³ of ceramic and concrete go to the foundation; 160 m³ of marès are reprocessed into 1,700 cyclopean concrete blocks with 40 % recycled marès in their mass. The blocks are stacked as load-bearing walls, reducing thickness by 10 cm on each floor to directly support the CLT slabs.
The floor plan is organised around a stair core at the corner and a walkway in the interior garden from which the apartments —almost all dual-aspect— are entered. The façade exposes the structural system —vertical end walls of the blocks, horizontal timber slabs—, with the porous texture of the recycled marès shifting under the lateral Mediterranean light.
