The Westerfeld House, designed by Henry Geilfuss, was built in 1889 for banker and candy baron William Westerfeld, one of many prosperous German immigrants who built grand homes in the area around Alamo Square. This great wooden palazzo is a pure expression of the style, Stick Italian Villa, with its tower, square bay windows and strong vertical line.

Among its subsequent owners was John J Mahoney the builder of the Palace Hotel, the St. Francis Hotel, and the open air Greek theater on the campus of the University of California in Berkeley.

The Westerfeld House is also National Register Listing 89000197.
