A unique architectural home in East Hampton, New York, has been offered for sale by the U.S. Government for $2.75 million.

Known as the Arc house, the semi-circular residence was designed by architect Maziar Behrooz in 2010. Behrooz took inspiration from the shape of an airplane hangar and built the structure directly into a hillside.

The curvilinear home is set on three acres and spans 6,400 square feet, with four bedrooms and four baths in total. Since the home is built into the hillside, roughly half of the floor plan is actually underground. The main ground-level floor features a spacious open-concept floorplan with walls of glass.

The residence is crafted from glass, stone, and wood, and boasts a 30′ x 60′ main living area complete with 16-foot-high ceilings. The interiors contain a huge amount of textural and pattern variation; accents include limestone, black walnut floors, and lacquered applewood, as well as tile and built-in shelving.

The minimalist kitchen is located within the main arched space and boasts a center island and top-of-the-line appliances. Downstairs, future residents will enjoy the rec room and gym.

The lot is very private, with a fire pit, a hot tub, and a swimming pool punctuating the acreage.
