One of a kind estate in gated Tiburon on the market for the first time. The sprawling property is tucked into a quiet court and boasts one of the largest lots in the community with nearly half acre of space. The sought-after floor plan offers a welcoming front courtyard, formal and informal living spaces, first floor en-suite, expansive primary suite, and a two-story casita. The Santa Barbara style finishes include white, smooth imperfect walls, terracotta floors, dark shutters, and exposed ceiling beams. Other highlights include a wine closet, walk-in closets with built-ins, additional washer/dryer in the primary suite, balconies, an updated chef's kitchen, and more. The show-stopping yard was designed by award-winning architect Michael Glassman. Complete with a pool and oversized spa, covered patio with a fireplace, lighted sports court, outdoor kitchen, custom play structure, and meticulous formal gardens, this backyard truly has it all. Accessed from the courtyard, the rare casita option has a living room with a fireplace and wet bar, bedroom, full bathroom, and large closet. Finally, the ideal East Roseville location is close to medical and fitness facilities, shopping, dining, trails, and freeway access.
