Opening home details…
One of the landmark estates of San Marino/Pasadena, the William K Jewett House and Gardens, also known as Arden Villa, is spread over a gated and level nearly three acres of landscaped grounds, including: The main and secondary homes, two pools, tennis court, green house, reflecting pond and expansive lawns and formal gardens. Designed by the venerable team of Sylvanus Marston & Garrett Van Pelt, and completed in 1915, the entire estate, as well as the secondary Mid-Century Modern home, with separate pool and gated driveway, underwent a massive renovation and redesign in 2019. In addition to systems and structural updates, Clements Design masterfully married existing 100+ year old handcrafted detailing, with modern amenities and design. So difficult, and rarely accomplished, the estate exudes the stalwart characteristics of the Gilded Age, at the same time feeling avant-garde, imaginative, and creative. Set behind its grand wrought iron gates, the home and gardens have provided unparalleled privacy for its residents as well as played host to a rich history of guests, including: Buster Keaton, the Marx Brothers and the Dynasty television series. Shown only to prequalified buyers.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
