This pool house in the backyard of the Classic Informality extends living space into the outdoors. Beneath a curving roof topped by a cupola, the terrace allows the family views of the pool in the comfort of the shade. The shingle roof complements the new home, while the shape adds a touch of whimsy. Inside, a living room, dining room, and kitchen enable the family to make the most of their outdoor space, without sacrificing indoor amenities.
