Rarely does a home of this magnitude and pedigree become available so close to downtown Los Altos. Originally the personal residence of Tarlton Properties' founder, this ~4,025 sf estate offers an uncommon level of above-ground scale on an expansive, oversized private lot. The 2020 renovation transcends typical luxury, focusing on a "clean" living environment powered by a sophisticated Messana radiant heating and cooling system. This high-performance system provides silent, draft-free comfort, making the home a true sanctuary of well-being. The aesthetic is equally refined, defined by Level 5 smooth drywall, wide-plank French Oak, and custom Shinnoki Frozen Walnut cabinetry. A chefs kitchen with Wolf and Sub-Zero appliances flows into a Great Room featuring limestone surrounds and linear fireplaces, while the primary suite offers a spa-like retreat with NuHeat floors and Dornbracht fixtures. Sustainable excellence is woven throughout, from the 15.4kW solar array and Tesla battery storage to the standing seam metal roof. This is more than a residence; it is a meticulously engineered masterpiece of comfort, volume, and prestige in the heart of Old Los Altos.
