While Charles Gwathmey may be best known for his 1992 renovation of Frank Lloyd Wright’s Guggenheim Museum, the acclaimed architect started making marks in the design world decades before—beginning with the Gwathmey House, which he created for his parents in 1965.

Two years later, he completed the Sedacca House in East Hampton, New York. Widely celebrated for its geometric style, the home has only switched ownership a couple of times. Last sold in 2016, it is now seeking a new buyer for $2,500,000.

The 1,200-square-foot dwelling is tucked away on a forested lot, and its simple material palette of wood and glass helps it blend into the site. According to a 1993 New York Times interview, Joseph Sedacca—a graphic designer who commissioned the home—granted Gwathmey full creative freedom for the project. “I had almost three acres of land, and I told Charles all I wanted were two bedrooms and a wonderful kitchen.”

Gwathmey checked off both boxes for Seddaca—and more. With 18-foot ceilings and glass walls, the cuboid living spaces serve as the heart of the home. One of the bedrooms is nestled just steps down the hall, while the other sits on the upper level and can be accessed via a spiral staircase.

The curvaceous part of the home houses the kitchen, which is fitted with new stainless-steel appliances, and there are also three bathrooms with upgraded fixtures and finishes. Despite these modern updates, the home stays true to Gwathmey’s original design, as a previous owner consulted with the architect while renovating the property.

A heated pool awaits in the backyard, in addition to a revamped Airstream camper which currently acts as a small guesthouse. An original storage shed is also included. “What Gwathmey created with the Sedacca House has become a piece of architectural history, lauded for its innovative use of materials and geometric forms,” says listing agent Michael Schultz. “With the home now on the market, this is a once-in-a-lifetime opportunity for any aficionado of good design to make this storied residence their own.” Scroll ahead to see more.

19 Northwest Landing Road in East Hampton, New York, is currently listed for $2,500,000 by Michael Schultz of The Corcoran Group.
