Excavated exterior spaces 
This house ingeniously solves the indoor-outdoor spaces gradation. The large unitary volume has perforations on the three facades, connected with each other. Two of them are joined with a space, the outside dining and barbecue, which is only closed for security and perhaps privacy. A large sliding glass with carpentry separates this space from another, a little more inside with the kitchen and the living room. This second space can be fully opened or closed with two sliding woodworks."
