Graycliff
Also known as: Darwin D. and Isabella R. Martin Summer Estate
Why it's listed
Graycliff is a lakeside summer estate in Derby, New York, set on a narrow eight-and-a-half-acre parcel above a sixty-five-foot cliff on Lake Erie. Frank Lloyd Wright designed it for Buffalo businessman Darwin D. Martin and his wife Isabelle, who bought the land in 1926. The property includes a two-story stucco and fieldstone house, a garage with servants' quarters, a boiler house, a gardener's cottage, a steel stair tower to the shore and a designed landscape with a sunken esplanade. The house opens toward the lake through French doors, cantilevered terraces and steel casement windows, with a massive stone chimney at its center. Letters between Wright and the Martins record changes to the plans, including abandoning a two-story living room and keeping the porte cochere. Later changes include a 1950s chapel addition and the loss of original plantings in the 1960s, though the plan and many interior finishes survive. The estate was listed as an example of Prairie School design.
Significance in brief: The nomination presents Graycliff as a Prairie School summer estate designed by Frank Lloyd Wright for Buffalo businessman Darwin Martin. The house, garage/servants' quarters, boiler house, gardener's cottage, stair tower and designed landscape reflect Wright's ideas of anchoring a house to its site and opening it to the lake. The surviving correspondence documents the client-architect negotiations over its design, and the property is recommended as locally significant.
