Sustainable design and meticulous execution highlight this superbly located residence, rebuilt with a vision of the future in mind. A highly efficient net exporter of power, 39 Alvarado delivers refined, sophisticated living within the most thoughtful envelope. Sweeping views of Mount Tamalpais and its ridge lines create the perfect backdrop for this in-town gem located on one of Mill Valley's best streets. Nearby, the energy of Downtown beckons and Boyle Park, buzzing with activity, is just a stone's throw away. Outside, the understated palette has a distinctly Mediterranean flair, blending with a native, drought-resistant landscape. Thoughtful fire resistant construction materials provide peace of mind. A veritable orchard of fruit trees punctuates the self-reliant nature of the property and is a direct beneficiary of what may be the best sun exposure in town. The interior of the home features an exceptional floor plan and a strong connection to the outdoors. On the main level, your eyes are immediately drawn to the wide-open living area and stunning natural light. High ceilings and a full-width wall of bi-fold glass doors frame an expansive blue-slate deck, extending living seamlessly outside. The kitchen oversees everything and truly is the heart of the home, perfectly outfitted for those who love to cook and entertain with Carrera Bella marble, Caesarstone, and top-of-the-line appliances. The primary bedroom suite, with its spa-like bathroom, and two complementary bedrooms with a shared bathroom complete the upper level. Downstairs, a flexible en-suite is perfect for guests or as an in-home retreat and leads to a lower deck replete with a hot tub overlooking a private oasis. A huge storage room, laundry room, systems room, and two-car garage offer great utility. Street-to-street access eases the daily routine. Eco-friendly systems include water catchment/purification, 9-zone radiant heat with Ecobee thermostats, Enphase photovoltaic solar panels, two Tesla Powerwalls, a Zehnder air ventilation system, central vacuum, motorized clerestory windows & deck awnings, plus much more. Proximity to world-class hiking trails and award-winning schools add the icing to this already delectable offering. This is truly Marin living at its best!
