History

George Kelham was one of the most productive architects in the Bay Area in the early 20th century, responsible for major civic and commercial buildings including the San Francisco Public Library’s main branch (1917), the Russ Building (1927), and numerous hotels and office towers. The Shell Building commission, received in the late 1920s from the Shell Oil Company of California, gave Kelham the opportunity to work in the new Art Deco idiom at a scale and ambition that matched the era’s commercial confidence.

The brief — a prestigious oil company headquarters at a prominent Financial District corner — called for a building that would announce Shell’s California operations and serve as a symbol of the company’s modernity and prosperity. Kelham’s response was a stepped tower in terracotta and brick whose ornamental programme incorporated the scallop shell motif of the Shell corporate identity into the Art Deco geometric vocabulary of the facade: the result is a building whose client identity and architectural identity reinforce rather than contradict each other, a rare achievement in commercial architecture of the period.

The building was completed in 1929, just months before the stock market crash of October that year. Shell Oil occupied the building as planned, and it remained a corporate landmark through the mid-century decades. A series of subsequent tenants maintained the building’s status as a prestigious Financial District address; the landmark designation, which recognised the integrity of both the exterior terracotta and the lobby interior, has protected it from the kind of strip-and-reclad treatments that altered many of its contemporaries in the postwar decades.
