Percy & Hamilton

Percy & Hamilton was an architectural firm in San Francisco, California during 1880 to 1899.

The firm was a partnership of George Washington Percy (1847–1900) and Frederick Foss Hamilton (1851–1899). During the period of 1890 to 1900, they designed numerous residences and churches in the Pacific Heights area. Many of their works were destroyed in the 1906 earthquake; others were destroyed for redevelopment. Several of their works survive and are listed on the National Register of Historic Places.
