The Arc House in East Hampton, New York, is a partly buried, arch-roofed home by Maziar Behrooz Architecture, completed around 2010 and about 6,400 square feet. It was designed with the look of an airplane hangar in mind, and it sits on a plot under an airport flight path and beside a train line, a site most architects would have treated as a problem.

How the arch works
The structure is a single self-supporting corrugated steel arch. Because an arch carries its own load, the main living spaces need no interior columns. Reports describe the arch as roughly 39 feet in radius with a peak ceiling height of about 16 feet.
The idea came from industrial building. The architect wanted to borrow a method normally used for hangars and shelters and apply it to a house. Under the arch sit the open-plan dining, living and kitchen areas. Behind it, a flat-roofed wing built from structural insulated panels holds the more private rooms, and the lower volume houses an office, a sitting room, a garage and workout space.
Dealing with the flight path and the train line
Instead of fighting the noise, the design buries more than half of the house. A green roof covers the garage wing, and a courtyard lets cool air circulate for passive cooling. Rather than leaving the flat plot flat, the landscaping creates changes of level so the house sees more than one horizon.
Energy features
The house uses geothermal heating and cooling, closed-cell foam insulation and high-thermal windows under a metal roof. Rainwater is collected from both ends of the arch. The project’s own description says energy use is significantly lower than a conventional home of this size. We have no metered figures, so treat that as the designer’s claim.
Awards
Under its early name, Hangar House, the project received an AIA Peconic Honor Award in the project category in 2009. In 2011 it won Best Metal Roofing at the MCN Building and Roofing Awards.
Sale history
The house at 50 Green Hollow Road was bought in 2015 for about $3 million, listed at $2.75 million in 2019 and sold that year for roughly $2.17 to $2.18 million, according to separate reports that differ by a few thousand dollars. We list the range because no single figure is consistent across sources.
