Bourn Mansion

Bourn Mansion is a Tudor and Georgian-style house in Pacific Heights featuring 27 rooms, 14 fireplaces, and red brick construction with traditional English architectural details. The residence spans roughly 9,762 square feet (907 square meters) along Webster Street.

William Bowers Bourn II commissioned architect Willis Polk in 1896 to design the house, funded by wealth from the Empire Mine in Grass Valley. The completed structure became a model for residential design in San Francisco when finished.

The mansion served as a gathering place during the 1970s when its owner hosted artists and musicians regularly. This period established the house as a social center in the city's cultural circles.

The building underwent extensive renovations in 2011 with seismic reinforcement to meet current safety standards for residential use in San Francisco. The size and layout of the mansion make it worthwhile to allow time for a thorough visit.

The brickwork patterns and stone masonry of the house departed from typical conventions and established new standards for San Francisco construction. These crafted details reflect the innovation Polk brought to the design.
