Originally built in 1925, 165 Elm Avenue is a thoughtfully updated, design-forward Sycamore Park home with exceptional family functionality, rare flat outdoor space, and the kind of indoor/outdoor flow that makes Mill Valley living feel effortless. Set on a sunny corner lot in one of Mill Valley's most beloved neighborhoods, the home blends classic architectural charm with warm, modern updates. Light-filled interiors, hardwood floors, curated lighting, fresh paint, and cohesive designer finishes create a turnkey feel while preserving the soul and personality of the original home. At the center is an expansive skylit kitchen and dining area designed for real life and real gathering. A rebuilt oversized island, updated cabinetry, wine refrigerator, newer appliances, Morris & Co. wallcovering, and garden-facing windows bring beauty, function, and natural light together in one of the home's most memorable spaces. Adjacent living areas flow easily to multiple outdoor entertaining zones and a large flat turf yard, ideal for dining, play, and long afternoons in the sun. The vaulted upper-level space offers a peaceful retreat with abundant natural light, treetop outlooks, and a beautifully refreshed bath with new vanity and updated fixtures. Adjacent to Park School and directly across from Boyle Park, 165 Elm captures the rare balance of convenience, community, privacy, and everyday livability that defines Sycamore Park at its best.
