Few buildings on the Santa Monica coast have lived as many lives as the Hotel Casa Del Mar at 1910 Ocean Way. A striking example of the opulent architecture of private beach clubs that defined the Southern California coast in the 1920s, it was completed in 1926 at a cost of $2 million, originally serving as the Club Casa Del Mar, an exclusive beach club. Architect Charles F. Plummer designed the structure in the Renaissance Revival style, drawing inspiration from Italian palazzos. Its most iconic features include a soaring double-height lobby with coffered ceilings, arched windows overlooking the Pacific, and intricate Mediterranean tilework. During its peak as a beach club, it was one of the most opulent social hubs on the West Coast, catering to the era’s wealthy elite.

The building’s role shifted dramatically following World War II with the decline of the private beach club era. In the 1960s, the property became the headquarters for Synanon, a controversial drug rehabilitation program. The elegant ballroom and social halls were repurposed for communal living and “the Game” sessions, a confrontational form of group therapy. The fortress-like atmosphere and unconventional activities of this period were a far cry from the Jazz Age parties the building had once hosted.

In 1978, the building entered a new phase when it was purchased by Nathan Pritikin to serve as the Pritikin Longevity Center. The facility became a world-renowned destination for health and diet reform regimens designed to reverse heart disease. The grand rooms that hosted jazz bands and Synanon sessions were then converted into medical consultation offices, exercise rooms, and dining halls serving heart-healthy cuisine. This period helped cement the building’s importance to the modern health and wellness movement in California.

A massive $50 million rehabilitation in the late 1990s restored the property’s original grandeur, reopening as the Hotel Casa Del Mar. The renovation meticulously preserved historic architectural details such as ornate ceiling moldings and a grand staircase while modernizing the interior for high-end hospitality. Today, it stands as a National Register Landmark, representing a unique historical timeline that spans the heights of the Jazz Age through controversial social movements of the 1960s, and the birth of the wellness industry.
