It was built in 1889 and designed by architect Henry Geilfuss for baker William Westerfeld.","why_significant":"The nomination argues the house embodies the distinctive characteristics of a type and period of construction and has high artistic merit, under Criterion C. It is widely seen as a symbol of San Francisco Victorian architecture and is probably the largest and most ornate house by Henry Geilfuss. It also has some added significance as the 1896-1918 home of building contractor John Joseph Mahony.","narrative":"Perched on a hilltop corner about a mile west of San Francisco's City Hall, this large wooden house at 1198 Fulton Street was built in 1889 for baker and confectioner William Westerfeld. Architect Henry Geilfuss gave it a tall, narrow form with square bay windows, a bracketed roofline, finials, Corinthian columns and a square tower. The interior has carved wood paneling, mantels and built-in cabinets. Its integrity is high; a garage added before 1912 is the main early change, along with a staircase and east-side alteration made around 1901. The house is considered probably Geilfuss's largest and most ornate work and is widely recognized as a symbol of San Francisco Victorian architecture. It is also a designated local landmark. John J. Mahony, of the Mahony Brothers contracting firm active in rebuilding the city after 1906, lived here from 1896 to 1918. Later uses included a Russian emigre community center, a rooming house and a 1960s commune.","period_of_significance":"1889","architect_builder":"Geilfuss, Henry","architectural_style":"Stick/Eastlake","criteria":["C"],"status_note":"Described as having high integrity and largely unchanged exterior, with ongoing restoration by the current owner.
