San Francisco’s deluxe Ritz Carlton Hotel was originally designed by the prominent East Coast firm Napoleon LeBrun & Sons in 1909 as the West Coast headquarters of the Metropolitan Life Insurance Company. After subsequent additions and several decades of office use, the building became Cogswell College, eventually reopening in 1991 as the Ritz Carlton. Massive columns, a detailed architrave and cornice, and decorative lion’s head medallions, all constructed of white and polychrome terra cotta, make the Ritz Carlton a magnificent example of neoclassical design. ARG Conservation Services, acting as the General Contractor, oversaw the ongoing restoration of the terra cotta facades, rehabilitated the metal-framed windows, and addressed graffiti removal and prevention using a coating treatment.
