10 Santa Yorma Court Exceptional San Marin residence tucked away on a premier quiet cul-de-sac backing directly to the Mt. Burdell Open Space Preserve with no rear neighbors. Boasting over $400, 000 in documented capital improvements, this rare 5-bedroom home offers dramatic, multi-directional views stretching southwest toward Pleasant Valley and west toward the rolling peaks of the Verissimo Hills. The main level features high-performance Milgard Tuscany dual-pane windows, James Hardie Cedarmill siding, and over 1, 400 sq. ft. of Mirage Umbria Maple engineered hardwood flooring. At the heart of the home, a light-filled gourmet kitchen includes a butcher-block island, double wall ovens, a walk-in pantry, and a bay-window breakfast nook framing views of Mt. Burdell. The main level flows into formal living and dining rooms with dual travertine fireplaces, an open family room, and a dedicated executive office with scenic window vistas. Upstairs, the expansive primary suite serves as a peaceful retreat with a corner fireplace, private view balcony, and a down-to-studs renovated spa bath with Nu-Heat floor heating, DuraSupreme custom vanity, and Riobel thermostatic fixtures. The secondary hall bathroom is equally refined, featuring Origin Sky Blue tile, Mykonos Thassos/Blue Celeste floor mosaic, and a KOHLER deep soaking tub. Outdoors, the expansive grounds feature a custom System Pavers patio with a built-in fire pit, stamped concrete walkways, lush lawn, and terraced gardens. A secured rear access gate opens directly onto Mt. Burdell's miles of open-space hiking trails. Complete with a 2025 mitered Taj Royale Quartz laundry suite, a whole-house 22kW Generac standby generator with acoustic soundproofing, and a 3-car garage, this turnkey sanctuary delivers an unparalleled Marin lifestyle near top-rated schools!
