Set in Pasadena’s coveted Linda Vista neighborhood, just moments from the Rose Bowl and the city’s cultural heart, this rare architectural residence offers a lifestyle of timeless modern luxury. Commissioned in 1955 by celebrated illustrator Harry O. Diamond and designed by Thomas Matthias, the home is a striking example of mid-century, defined by clean lines, dramatic walls of glass, and an effortless connection to nature. This home has been noted and featured twice in Sunset Magazine for its architectural design and estate style gardens. In true Mid Century design, high-beamed ceilings and walls of glass open to views of the sparkling pool and lushly landscaped gardens, blurring the line between indoors and out. The lush mature landscaping frames the pool while the water reflects the dappled sunlight filtering through the trees. The grounds offer unparalleled elegance and privacy with a manicured yard, a vine draped pergola, abundant fruit trees, and multiple outdoor sitting areas, creating a sublime setting for refined entertaining and peaceful retreat. At its core, a breathtaking two-story enclosed atrium anchors the residence serving as a lightwell and providing a serene focal point for common areas and daily living spaces; a rare architectural statement in mid-century design.The home balances sophistication and comfort. The upstairs primary suite is a private sanctuary, with expansive glass walls and a balcony overlooking the central atrium. A spacious downstairs suite with vaulted ceilings, clerestory windows that invite natural light, and an expansive walk-in closet serves as an ideal retreat or second primary bedroom. Two additional bedrooms offer refined flexibility, easily serving as guest suites, private offices, or personalized retreats. The kitchen features an open layout that seamlessly connects the family, dining, and living areas, creating a harmonious flow that results in openness and balance. This home is an opportunity for collectors of design and architecture. Situated in one of Pasadena’s most desirable enclaves, the Harry O. Diamond Residence reflects architectural pedigree, timeless modern design and a piece of California’s rich artistic legacy.
