As part of IBAVI’s collective research (Institut Balear de l’Habitatge), this public housing building combines traditional materials and construction systems with contemporary strategies of prefabrication and energy efficiency with low environmental impact.

The layout of the apartments optimizes the site’s orientation and climatic conditions. All units feature cross-ventilation, optimal insulation and summer solar protection. The position of the open staircase and courtyard has been defined according to prevailing winds. The roof, occupied by an extensive solar array, simultaneously generates energy and acts as a ventilated chamber, minimising summer heat gains.

All walls and partitions are made of marès stone from local quarries, and the horizontal structure is built from prefabricated cross-laminated timber slabs. Windows and shutters are made of wood, following local tradition. The result is a fully passive contemporary dwelling with a low environmental footprint and complete continuity with the island’s constructive culture.
