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.
