- Address: 3905 Mansion Ct, NW and 3905 Reservoir Rd, NW
Hillandale, located at 3905 Mansion Court, NW, was built from 1922 to 1925, during an era when period houses were popular. Hillandale has been recognized as "one of America's last great residences." The original estate was sited north of Reservoir Road and west of 39th Street and included more than seventy acres of mature forests, meadows, and landscaped grounds. The present estate is located north of Reservoir Road, west of 39th Street, and east of Glover-Archbold Park. Today, five acres, which include the main residence, remain intact; the gatehouse, located on Reservoir Road is part of the designated estate. The buildings are representative of the rural Italian Renaissance Revival style and serve as unique examples of the style in Washington, DC The main residence at Hillandale is majestically perched atop a hill. The villa was designed with an irregular plan to suggest that the residence expanded over time. The architect, Josephine Wright Chapman, designed rooms, balconies, and second-story observation points to allow for sweeping views of the site. The buildings have a stucco finish, irregularly arranged casement windows, a limited amount of ornament, and terra cotta tile roofs. - NRHP Registration 11 December 1994
