Bates Masi Architects recently created this contemporary residence for a large family in Sagaponack, New York, USA. It is situated between the Atlantic ocean and a lake which required the home to be constructed from durable materials that could withstand harsh, wet conditions. The owners wanted a house for their large family and numerous guests with a lawn, swimming pool, pool house, garage, and sports courts on a site with a limited building envelope due to coastal and wetland zoning. The large program, relatively small footprint, and daunting regulations dictated a building envelope densely packed with program that stood as a barrier between the ocean and the pond. Thus the design process was one of subtraction rather than addition: carving away at the solid mass of the house to reconnect site features and views and to distill the experience of the place. Spaces run the full width of the house with floor to ceiling sliding doors on both sides. The spaces create apertures through which views, light, and air completely penetrate the house, dissolving its mass. The design strategy to accommodate the extensive program is to nest spaces within one another. Operable partitions pull out from the walls of the living room, carving out a media room within the living room when privacy is desired.
