Rare legacy estate property featuring a stunning, Don Olsen-designed custom home, PLUS a separate new guest house with its own address, all set on a sprawling, private lot comprised of six original parcels less than 1.5 miles from downtown. This one-of-a-kind property presents a unique opportunity, boasting unmatched privacy, peace and quiet, along with stunning, sunny views from Belvedere to Berkeley, framed by Mt. Diablo in the background. The main residence was rebuilt from the ground up in 2010, using natural materials to perfectly complement the heritage redwoods found right outside. Walls of tall windows and glass doors, along with multiple expansive view decks, embody the literal definition of an adult treehouse escape in this tranquil, natural setting. Recent design upgrades by local designer Kress Jack incorporate accents of bespoke tile, vibrant color, and high-end finishes that complete the contemporary interior. The main house is 2,616 sq ft, with 3 bedrooms and 3 full bathrooms, including a primary suite with a cozy fireplace and a sliding glass door that opens onto its own deck, as do most rooms throughout the interior. The sizable 770 sq ft guest house was newly constructed in 2012 and features 1 bedroom, 1 bathroom, a full kitchen, a dining area with built-in banquette, and a living area complete with its own fireplace. There's a wide variety of uses here guest quarters, a home office, music studio, or gym PLUS it has its own dedicated parking and entrance. The Pipeline and Dipsea Trails are close by for walking, hiking, and biking, though the abundance of natural light and the breathtaking, wide-open views of the bay, valley, and surrounding hills may urge you to stay home for days on end. Newly refinished decks offer additional outdoor space, and whatever you do, don't miss the private spa deck up top.
