Hill-Crest, Presidential residence in Washington, US.

Hill-Crest is a 35-room mansion on 1.4 acres overlooking Lake Washington, with a 12,800-square-foot interior finished in Douglas fir and Honduran mahogany. It also has an elevator, a pipe organ, and a separate carriage house.

The mansion was built in 1907 for lumber magnate Edwin Ames and his wife Maud Walker Ames, then bequeathed to the University of Washington in 1931. This bequest transformed it into the official residence for the university's presidents.

The residence maintains its status as the official home for University of Washington presidents, requiring them to live within its walls as per bequest conditions.

The residence is not open to the public as it serves as the university's official residence. Visitors can view the building's exterior and appreciate its architecture from the street.

The house is also called "the 808 House" and "Walker-Ames Mansion". Its 2013 market value of about $8.5 million made it then the most expensive public university presidential residence in the United States, worth more than the Washington Governor's Mansion. A full-time staff of majordomo, chef, gardener and housekeeper runs the property.
