Arranged along a single elegant line, the pier house is comprised of two linked buildings and a sequence of outdoor spaces and pools. A 2,000 sf main house and a 950 sf guest house slip past each other on either side of the path, opening onto and defining the main courtyard. One of the modern houses in Sagaponac, it achieves net zero status as a result of a highly insulated envelope, efficient fixtures and mechanical systems working in tandem with a geothermal system and photovoltaic array.  [3,000 sf new construction]
