Its Victorian Gothic ironwork cornices and balconies, which mask fire escapes, relieve an otherwise severe facade. It is also a notable work of Willis Polk, a leading Bay Area innovator in design.","narrative":"Located at 130 Sutter Street in San Francisco, this eight-story steel-frame building carries a glass front and masonry side walls, with the high ceilings typical of loft buildings. Willis Polk designed it as an investment for the University of California, and it was dedicated in 1918 to Andrew S. Hallidie, a University regent known for inventing the cable car in 1872-73. Its street elevation anticipated the glass curtain wall: the floors are cantilevered, so no columns appear at the facade, and four columns sit behind the glass. Victorian Gothic iron cornices and balconies, once painted blue and gold, hide the fire escapes and soften the facade. The nomination holds the building to be of great importance to San Francisco's architectural history and to Polk's reputation as an innovator who helped rebuild the city after 1906.","period_of_significance":"1918","architect_builder":"Willis Polk","architectural_style":"Victorian Gothic ironwork on a glass curtain wall facade","criteria":[],"status_note":"Condition is marked good and unaltered, though the form notes a much altered ground-level commercial space.
