Thereafter the projects attributed to Polk were carried out by his firm, either from plans in which the architect had had a hand, or based upon his design principles. The Mediterranean Revival style of the St. Francis Yacht Club and the Spanish Revival style of the New College of Californiareflect Polk's academic ecclecticism, as does the Georgian Revival design of the house at 3450 Washington Street.

Willis Polk exercised a dominant influence on San Francisco architecture for nearly four decades.

A hipped-roof pavilion, which houses a remarkable set of WPA murals by Lucien Labaudt executed in 1936-37 illustrating recreational activities in San Francisco. Polk was also the architect for the Portals of the Past on Lloyd Lake, an Ionic colonnade that originally graced a Nob Hill mansion he designed. It burned in 1906 (Woodbridge and Woodbridge 1992: 166).

Willis Polk designed this simple, unadorned Spanish Revival structure with handmade roof tiles, which was restored in 1996. Originally built with a lounge and changing rooms for ocean bathers on the ground floor and a municipal restaurant on the second floor, it has also served as a tearoom, headquarters for coastal defense forces during World War II, and a Veterans of Foreign War bar. Funded by the WPA, Lucien Labaudt, the director of a successful school of fashion and design, painted the murals in 1935 and then supervised the mosaic work of Primo Caredio and the wood carving in magnolia on the columns and balustrades by Michael Von Meyer (Wiley 2000: 372-73).

A similar composition to the Native Sons Building, but with a more restrained use of materials and decorative detail. But observe that the ground floor drips with stony water which even runs over the keystone above the entrance arch. Inside on the north wall over the elevator is a mural by Maynard Dixon of the Sonol Water Temple built by the Spring Valley Water Company, the original clients for this building. The owner, William Bourn, was Willis Polk's patron. Polk designed his house at 2550 Webster Street and Filoli, his estate in Woodside (Woodbridge and Woodbridge 1992: 12).

A reinforced concrete office building with a stone base, originally designed for the Spring Valley Water Co. A three part vertical composition with Renaissance/Baroque ornamentation. The business office inside is decorated with murals by Maynard Dixon (Corbett 1979: 145).

After this venerable San Francisco institution suffered fire damage in 1976, the interior was redone by Marquis (Woodbridge and Woodbridge 1992: 94).

...one of the city's elite private gathering places, designed by Willis Polk in 1928 in the Mediterranean Revival style (Wiley 2000: 346).
