Two concrete boxes superimpose and slide, creating space for open-air life. The boxes separate the public spaces on the ground floor from the private spaces on the first floor. A series of boxes of different materials cross the concrete ones and enclose more defined spaces - access and gallery in a wooden box; utilitarian spaces such as kitchen, laundry room, employees’ and guest bathrooms in a black stone-slab box; dinning-living room in a crystal box. On the second floor a second crystal box enfolds the Jacuzzi and flies over the garden generating a bigger shade-area in the terrace. The materials undress themselves showing outside what they can offer inside. The concrete, heavy and opaque, decompose going through the black stone-slab more handmade and cosy to get to the crystal box totally ethereal. The spaces take place through the boxes, which define the ambient and the relationship between the program and nature.
