The Poolhouse is one of thirty-four houses designed for 188 acre site in Sagaponack on Long Island, New York. The site includes a 13 acre reserve with walking paths, individual vegetable gardens and a tree farm.


‘This development is an anti-subdivision, the opposite of the usual, shoddy, conformist repetition that has made the very word subdivision a pejorative. Our intent…is to allow a diverse community to evolve, where the houses express the individual voices of each architect and homeowner.’ The Brown Companies, developer of The Houses at Sagaponac.

Eight S-shaped frames define the volume of the glass- and wood-clad Poolhouse, Sagaponac House #33. The steel S-frames are organized in groupings placed perpendicular to one another, creating interlocking singe- and double-height volumes. The S-shaped section allows the interior of the house to flow out to the garden while creating more enclosed, private spaces on the upper level. First floor living space concrete slabs extend outside as patios. On the second floor, the curving profiles are clad in wood, creating modifiable louvered facades for the bedrooms and adjoining terraces.

A blue mosaic-tiled swimming pool penetrates the first floor interior complete with a wet bar adjacent to the interior portion of the pool. A sheet of water cascades down into the pool from the upper level screening off the more private upper level spaces from view below. Large south-facing glass sliding doors open the double-height dining area out to the poolside patio, while glass pivot doors extend the living room out to the garden on the east. A glass garage-type vertical sliding door drops down to seal off the outside lap pool from the interior.
