An Architectural Masterpiece in the Old Quarry Enclave

Set within the private, unlit streets of coveted Old Quarry, 39 Tomahawk Drive is one of only 12 residences in this exclusive San Anselmo enclave. Situated near the end of a quiet cul-de-sac on ~0.83 acres, the home enjoys sweeping Mt. Tamalpais and hillside views, beautifully landscaped grounds, meandering pathways, multiple outdoor entertaining areas, and direct access to surrounding open space and hiking trails.

Originally built in 1989, this extraordinarily energy-efficient and mostly single-level home has been meticulously transformed over two decades, inspired by the Lodge at Torrey Pines and Yosemite’s Ahwahnee Hotel. Artisan craftsmanship, timeless architecture, and energy-efficient design are showcased throughout with hand-crafted cherry cabinetry, custom timber beams, Andersen A-Series windows and doors, hardwood floors, stained-glass accents, extensive built-ins, and exceptional custom millwork.

The dramatic living and family rooms both feature soaring ceilings, gas fireplaces with custom mantels, and walls of glass opening to wrap-around decks. The formal dining room adjoins a beautifully appointed chef's kitchen with custom cabinetry, handcrafted tile, a large island, bespoke copper hood, Sub-Zero refrigeration, dual dishwashers and sinks, double oven, warming drawer, and a climate-controlled wine cellar.

The primary suite offers Mt. Tam views, a sun deck, walk-in closet, sitting area, and luxurious bath with heated floors, two-person tub and shower, dual vanities, separate water closet with third sink, and abundant storage. Three additional bedrooms and a laundry room complete the main level.

The lower level includes a sound-isolated gym plus a spacious office/studio with full bath and plumbing for a future kitchenette—ideal for an au pair, in-law suite, or multigenerational living.

Outdoor amenities include an outdoor kitchen, gazebo, greenhouse, fountains, decks, patios, and Cal Fire-approved landscaping that blends seamlessly with the surrounding open space.

Sustainability features include 41 owned solar panels, two Tesla batteries, EV charging, whole-house air-conditioning and filtration, energy-efficient windows and doors, extensive insulation, ~3,700-gallon rainwater harvesting system, and a new Class-A roof with a 50-year transferable warranty.

Rarely does a home combine architectural craftsmanship, exceptional quality, environmental stewardship, and an extraordinary connection to nature as beautifully as 39 Tomahawk Drive.
