This residential project for three young friends who decided to build their homes together could be considered an architectural exploration of the theme of friendship. The corner lot in a residential area had already been chosen by the clients. Three buildings were constructed at 45 degree angles to each other pivoting around a fulcrum point planted with an olive tree - a symbol of friendship - and connected by a portico that anticipates the identical volumes of the three houses: each home is a single volume with a single-pitched copper roof. On the external facade the large double height window opens onto the pool. The walls are faced with tufo treated all'orvietana.
