Feusier Octagon House

The Feusier Octagon House is a three-story residence on Green Street with a distinctive eight-sided form and mansard-style roof. The building is crowned by a cupola that makes its unusual geometric shape clearly visible from the outside.

The house was built in 1858 by George Kenny and purchased in 1870 by French immigrant Louis Feusier, who added the third floor. The structure survived the 1906 earthquake and the subsequent fires without major damage.

The house represents a design movement of the 1850s that sought natural light and efficient space through unconventional forms. Visitors can see today how this architectural philosophy expressed itself in the eight-sided shape and the cupola on the roof.

The house sits on Green Street between Leavenworth and Jones Streets and is easily visible from the street. The exterior can be photographed by visitors, but the interior is not open to the public.

It is one of only two remaining octagonal houses in San Francisco and therefore holds great importance for the city's architectural history. Its rarity makes it a remarkable example of a design movement that has almost completely disappeared in most American cities.
