This Fire Island house is located directly behind beach-front dunes. The strict requirements of both FEMAand local codes regarding height, lot line, setbacks, and site coverage; the proximity of neighbors; and very specific view corridors all presented a host of challenges. Our response was to create a dynamic composition of three intersecting rectilinear forms, which is rotated on the site off the prevailing grid. This decision maximized both views and privacy. The volume at grade is delineated by dark, vertically slatted, wood breakaway walls, which obscure the support pilings and provide storage for water sports equipment. The center volume, clad in horizontal wood siding, houses bedrooms & baths and provides roof decks for the living level. The metallic clad upper volume contains a large, open-plan living space with spectacular water views.
