The Knoll House, 2 Oak Knoll Terrace, Pasadena, California

Listed for US$32 million. 

Bidding Open Through July 9—Current Ask: US$18 million

Holding the title of Pasadena’s largest residential home, ‘The Knoll House’, is a historic c1916 estate designed by renowned Los Angeles architect Myron Hunt and later expanded by Gordon Kaufmann AIA. Recently fully restored, blending handcrafted, historic finishes with modern construction, the property offers over 32,000 square feet, with 12,300 square feet of residence and 20,500 square feet of entertainment gallery space, with seven bedrooms, 10 full bathrooms, and 11 half bathrooms. Nestled on a tranquil private cul-de-sac, the home occupies 2.38 acres of land.

Listed by Josh Flagg, star of Bravo TV’s long-running “Million Dollar Listing Los Angeles” television show, of Compass, and Darrell Done and Carol Chua of Coldwell Banker Realty, ‘The Knoll House’ represents a rare opportunity to own a distinctive estate property featuring two remarkable turnkey structures. The first is an exquisite residence designed by two of America’s foremost architects: Myron Hunt, renowned for his work on iconic landmarks such as the Huntington Library, the Langham Huntington Hotel, the Rose Bowl Stadium, and the Hollywood Bowl, and Gordon Kaufmann, acclaimed architect of the Caltech Athenaeum, the Los Angeles Times Building, and the Hollywood Palladium. The second structure is an exceptional entertainment gallery crafted by noted architects Ladd and Kelsey, known for their work at the Norton Simon Museum.

The building’s current owners have spared no expense in meticulously restoring and renovating the property, guaranteeing the preservation of its architectural significance and historical importance. The result is a completely modernized estate, perfect for both intimate gatherings and large-scale events and offering unmatched indoor and outdoor entertainment facilities. Notably, this estate stands alone as the only known property in the nation to combine a fully restored historically significant home with a museum-grade entertainment gallery, further cementing its status as a pinnacle of luxury living.

“This sprawling estate celebrates a rich architectural history, and is today a shining example of a timeless aesthetic,” said Flagg. “The Knoll House is a spectacularly restored example of the grand trophy estates that once marked the pinnacle of refined living—and still do today.”
