It kept its original exterior construction and its eight-sided interior spaces. It also stands as a reminder of the mid-19th-century octagon house fad inspired by Orson Squire Fowler.","narrative":"Perched on Russian Hill at 1067 Green Street, this octagonal house was built about 1857 or 1858, though one source suggests as early as 1852. Its walls are a mix of cement or burnt lime, gravel and clay, following the method promoted by Orson Squire Fowler, whose book set off a national fashion for eight-sided houses. The original two-story building gained a third story with a Mansard roof and octagonal cupola later in the century. Details include quoined corners, brick chimneys, balustered balconies and a columned porch at the second story. Only two octagon houses are known to survive in the Bay Area, the other being the Colonial Dames Octagon on Gough Street. The house remained in the Feusier family for about eighty years and appears in city views from the 1850s and 1860s. It survived the 1906 fire, when its outbuildings were dynamited, and it still serves as a visible link to early San Francisco.","period_of_significance":"1857-58","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed as a private residence in fair condition; the interior is described as excellent and carefully maintained.
