The Marcel Breuer House at Pocantico is a wood-frame modernist-style house at the Pocantico estate in Pocantico Hills, New York, United States. It was designed by Marcel Breuer as part of the 1949 "House in the Museum Garden" exhibit at New York City's Museum of Modern Art (MoMA), curated by Philip Johnson, MoMA's director. The museum had made plans to exhibit a modernist house in its garden in 1948, to be designed by Frank Lloyd Wright, but design of the exhibit was instead awarded to Breuer. The exhibit opened in April 1949 and received 80,000 visitors over six months, becoming one of MoMA's most popular exhibits to date. After the MoMA exhibition ended, House in the Museum Garden was disassembled and taken to Pocantico, where it was reassembled by the Rockefeller family in 1950.
The design was intended to be constructed in two phases: the first phase consisted of two bedrooms for a family with young children, and additional rooms could be built as the children grew. The facade uses cypress board, with plate glass windows, and a roof with a V-shaped cross-section. Stone seating areas and standalone louvers partition the open space outside the house into several zones. Inside are stone floors that conceal a radiant heating system, along with wooden floors and ceilings. As designed, the bedrooms are placed at either end of the building, while communal areas such as living and dining rooms are situated centrally. One side of the house has a mezzanine. Closets and storage space are placed throughout the interior, and when the exhibit was displayed at MoMA, it was fully outfitted with interiors and furnishings designed mostly by Breuer. The Marcel Breuer House at Pocantico's design received mixed commentary from art and architecture critics, but its popularity helped increase public awareness of Breuer's designs.
