Design and construction of a single-family villa built in the Mondello area in the province of Palermo, a short distance from the sea in a modern style. In this villa one perceives the interpenetration of the internal spaces with the external ones and of the great light that invades the internal spaces from the outside. The villa is designed with two floors above ground and a basement with independent entrances. The two floors are served by a technical body (staircase) with direct light from the triangular-shaped skylight located on the roof. The same allows a rapid achievement of the three levels. Particular attention has also been paid to the distribution of specially designed outdoor spaces with several steps for large spaces on different levels.
