In keeping with the canons of bio-architecture, the materials chosen for the villas are mainly locally produced and natural. Tadelakt is used for the interior walls, a semi-gloss lime plaster finished with river stones and treated with black soap. The outside masonry is built with Poroton® blocks, a thermal insulating block made of fired clay and Diathonite, an eco-compatible thermoplaster made of natural hydraulic lime, cork, clay and diatomic powders. Several different materials have been used for the flooring. Outside local Sardinian stone has been used extensively. The windows, internal doors and external shutters are in wood, mahogany, walnut and teak. The windows are folding.
