Thomas T. Gaff House, NRHP contributing property and official residence at Dupont Circle, Washington, D.C., United States.
The Thomas T. Gaff House at 1520 20th Street Northwest is a Châteauesque-style building with symmetrical facades and intricate stone details throughout its exterior. The interior contains modern systems including a hot-air heating system, a dedicated delivery trapdoor, and specialized cork insulation in the wine cellar.
The house was built between 1904 and 1905 by architects Bruce Price and Jules Henri de Sibour for an Ohio industrialist who served on the Panama Canal commission. This early 20th century construction reflected a period of prosperity and growth in the neighborhood's residential architecture.
The residence has hosted numerous high-ranking guests, including a U.S. senator, a Cabinet member, and ambassadors from Greece and Colombia. Its role as a diplomatic and social venue has made it a significant gathering place in the city.
The house is located at the Circle plaza in an upscale neighborhood and visible from the street, making it easy to spot. Visitors should note that it remains a private residence and may be open to the public only during special events or designated occasions.
The house features a two-story Edwardian ballroom topped with a stained-glass dome that serves as a venue for charity events, formal dinners, and art exhibitions. This grand space represents one of the most distinctive architectural features of the building and attracts many special occasions.
