John Henry Hammond House

About

The John Henry Hammond House is a mansion at 9 East 91st Street in the Carnegie Hill section of the Upper East Side of Manhattan in New York City, New York, US. Designed by architects Carrère and Hastings in the Italian Renaissance style, it was completed by 1906 as the residence of lawyer John Henry Hammond and his wife Emily Vanderbilt Sloane Hammond. The Russian Federation owns the house and has used it as the Consulate General of Russia to New York City since 1994. The mansion is a New York City designated landmark.

The Hammond House is five stories high, with its fifth story set back from the facade. The mansion's limestone facade is rusticated on its lowest two stories, and each corner of the building has vertical stone quoins. The second story of the facade is designed like a piano nobile, while the upper stories have progressively smaller windows. The rooms were designed in the Louis XVI style, with features such as elevators and a squash court. When the house was built, the ground (or first) floor had a "T"-shaped entrance hall, a billiards room, a dining room, and a breakfast room. The reception rooms on the second floor—which included a ballroom, library, and music room—could accommodate hundreds of guests. The third and fourth floors were used as bedrooms. There is also an attic, which originally contained female servants' quarters and an infirmary, and a basement, with male servants' quarters.
