The 3,000-square-foot house rises over the crest of the dune like a cylindrical lantern that’s partially eroded on one side. The design began with the intersection of two geometric forms: an oval penetrated by a rectangle. It evolved from there through a series of artful incisions and overlapping planes, in the neo-Cubist spirit of sixties modernism and the early beach houses of Charles Gwathmey and Richard Meier. The architects refer to it as “sculpting volumes in space” with overhangs and recessed balconies that appear to be carved with a sharpened knife. The master bedroom hangs over a double height living space, while a curvilinear extrusion becomes a balcony with outdoor shower. The box-like part of the house contains an office and guest bedroom. To create a subtle sense of contrast, the rectilinear part of the house was clad in tongue-and-groove cedar siding, while the elliptical volume has smooth white stucco. A twenty-foot-high wall of glass slices through the twin volumes and creates a barely perceptible membrane between inside and outside. All interior walls are painted eggshell white and the floors are stained driftwood gray. The undercroft is enclosed behind a skirting of horizontal cedar slats that provides space for storage, a fishing station and parking for two cars.
