The 9-bedroom "summer cottage" was originally the centerpiece of a 300-acre (121.4 ha) estate, that was expanded to 400 acres (161.8 ha) early in the 20th century. The carriagehouse and other buildings have since been demolished, and the land subdivided, leaving the main house and boathouse on 2.4 acres (1 ha).
The boathouse's design is unusual: a square stone ground floor at lake's edge supporting a circular shingled second floor, ringed by a 360-degree deck. It relates to Furness's Undine Barge Club (1882–83) on Philadelphia's Boathouse Row, and the architect's own summer cottage, Idlewild (c. 1890), in Media, Pennsylvania.
The property was listed on the National Register of Historic Places in 1991.[1] In addition to the main house and boathouse, it includes one non-contributing building.
Ormonde is "architecturally and historically important as an outstanding early example of the type of large mansions constructed chiefly as summer residences by wealthy clients in the late nineteenth and early twentieth centuries near the shores of Cazenovia Lake in central New York."[2]
Ormonde is part of the Cazenovia Town Multiple Resource area.[3]
