In Sag Harbor, Modern Prefab ASAP House Is On the Market

The ASAP House, a pioneering prototype modern home with numerous advanced building technologies, was recently put on the market in Sag Harbor.

Some time ago, we wrote here about the ASAP House: a prefabricated, modular 4-bedroom home in Sag Harbor that was built for $265 per square foot (a relative bargain by East End standards). Since 2008, the house has been home to its Manhattan-based architect, Laszlo Kiss, and his family, and served as a prototype for his clients interested in modern green design at (again) relatively low cost. (It’s not uncommon for per square foot home building costs in the Hamptons to exceed $1000 per square foot, for example). Located on a quarter-acre plot, the house was built in a Pennsylvania factory and delivered to the Hamptons in three sections by truck and assembled on-site; the foundation was delivered separately in pre-insulated concrete slabs.

The four-bedroom ASAP House uses a geothermal heating and cooling system. Its light fixtures accept only energy-efficient bulbs and roof-top solar panels power and heat the house while the sun is shining. And, at night, the house takes power from the grid, drawing on the surplus it supplied during the day. Other notable design elements include a flexible interior layout; cedar porches at the front and back of the house that total 800 square feet; and a translucent pergola above the flat, solar panel-topped roof.

The ASAP House is of interest to us here once again because it’s now for sale. The 2500-square-foot home is listed with Sotheby’s for $1.4 million, considerably more per square foot ($560) than what it cost to build. The listing describes the ASAP House as follows: “An advanced, environmentally friendly home, photographed and written about in the New York Times for its environmentally friendly attributes. Urban Zen Meets The Beach. Open and airy living space with floor to ceiling sliding glass doors leading to the garden with solar heated gunite pool. Heating and cooling is geothermal and electric power is mostly solar. Quiet non though street and Paynes Creek is a stroll away. Conveniently located close to beaches, markets, farmstands and Sag Harbor Village.”
