Tucked away at the end of a peaceful West Novato cul de sac, this exceptional property presents a rare opportunity to own a thoughtfully updated residence with a fully independent newly constructed ADU, all set on an expansive usable lot with direct gated access to Pioneer Park. Offering an extraordinary combination of privacy, flexibility, and everyday convenience, this is a property designed to evolve with every stage of life. The inviting single level main residence blends timeless mid century character with carefully curated modern updates. Open beam ceilings, abundant natural light, dual pane windows, a welcoming fireplace with insert, and a beautifully updated kitchen create warm, inviting spaces that feel both comfortable and refined. The flexible floor plan easily adapts to today's lifestyle, offering space for a home office, media room, creative studio, guest accommodations, or additional living area. Energy efficient mini split climate systems throughout the home provide year round comfort and efficiency. A remarkable addition to the property is the newly built two bedroom, two bath ADU, thoughtfully designed as a true second residence with its own address, separate utilities, and independent heating and air conditioning. Whether envisioned as a home for extended family, multigenerational living, long term guests, a private executive office, or an income producing opportunity, the ADU offers exceptional versatility while preserving privacy for both homes. Beyond the interiors, the outdoor spaces invite year round enjoyment. An expansive deck overlooks beautifully landscaped grounds with generous areas for entertaining, outdoor dining, gardening, play, or simply relaxing beneath the mature trees. The private gate opening directly to Pioneer Park creates a seamless connection to acres of open space, walking trails, recreation, and nature, an amenity few homes can offer. Perfectly positioned in one of West Novato's most desirable neighborhoods, this exceptional property combines timeless architecture, modern comfort, and remarkable flexibility in a setting that is increasingly difficult to replicate. Whether accommodating a growing family, supporting multigenerational living, creating additional income, or simply enjoying the freedom of having space that adapts to your lifestyle, this is more than a home. It is a rare opportunity to invest in the way you want to live today while creating lasting value for years to come.
