High on the cliffs overlooking the sea, this residence exudes a sense of place—seemingly originating from the ledge that supports it. Jutting forms and crashing volumes are reminiscent of the relationship between the land and the sea. An irregular footprint radiates from the entry tower. Strictly following the client's wish for minimal use of structure and maximum use of glass, the walls rise up on ball bearings and effortlessly roll away. The second and third stories of the tower feature the master bath suite. With a glass-enclosed shower on an outside wall, the openness continues. The jacuzzi tub offers a 360-degree vista of the five lighthouses adorning the coast from Maine to Cape Ann.
