Williams’s sophisticated hospitality spaces projected a distinctly Californian vision of midcentury glamour, crafting backdrops for Hollywood’s elite—whether they were lunching at the Beverly Hills Hotel’s Polo Lounge, attending Ambassador Hotel galas, or sipping cocktails at Perino’s restaurant. This aesthetic rippled out from Los Angeles, influencing Williams’s commissions in Las Vegas, Hawai‘i, Mexico, and the Caribbean. As post–World War II optimism and tourism surged, everyone wanted to experience the dreamscapes that he designed.
In Los Angeles, Williams modernized classic hotels of an earlier era, drafting revitalization plans for not only the Beverly Hills Hotel and the Ambassador, but the Hollywood Knickerbocker, Beverly Wilshire, Sunset Tower, and more. In Palm Springs, he similarly brought the El Mirador back to hotel service after its wartime use as a military hospital.
Beyond Southern California, he exercised greater creative freedom, designing new resorts in Nevada, Mexico, and Cuba. His early presence in Las Vegas established a decades-long cross-pollination of architectural ideas between Southern California and Nevada.
Navigating these elite social circles and international projects, Williams’s professional stature offered him a measure of protection from racial exclusion, often making him the only Black figure mentioned among the civic leaders, businesspeople, and acclaimed architects who moved through these spaces.
