This waterfront home was designed for a family with deep roots in a historic island community overlooking Great South Bay. With access only by private ferry and no automobile travel allowed, the enclave remains much as it was a century ago. Bicycles are the standard means of travel so the house, which floats just above the native beach grass, was designed to connect to a wooden plank boardwalk that weaves along the shore, its elevation is nearly camouflaged among the surrounding trees. Inside, an open plan connects seamlessly to the outdoors through large sliding glass doors. Finish details such as indigenous rift sawn white oak on the walls, ceilings and floors, are a familiar nautical reference and a nod to the antique cottage that was original to the site.
