Fully reimagined. A rare, sun-drenched level lot of 10,001 square feet in Mill Valley — truly usable, all day. Views stretching toward Tennessee Valley. A detached fourth bedroom with full bath, ideal as a guest suite or private studio. Seamless indoor-outdoor flow throughout. We listed and sold 333 Richardson Way.

Finding a level lot in Mill Valley is, by itself, an achievement. Finding a level lot of 10,001 square feet that receives sun all day, in a neighborhood with easy Tam Junction access and Tennessee Valley views, is the kind of thing that buyers spend years waiting for. 333 Richardson Way delivers exactly this — and the home sitting on it has been fully reimagined to make the most of every square foot of that setting.

The renovation is comprehensive and considered. Clean architectural lines, excellent natural light throughout, and a floor plan organized around one guiding principle: seamless connection to the outdoors. The living areas open directly to the yard — the flat, usable yard — creating the indoor-outdoor flow that defines California residential living at its best. Multiple outdoor zones offer space for dining, lounging, play, gardening, and the unstructured weekend time that a private yard of this scale enables. The sunshine that fills the home from morning through evening is not incidental — it is the organizing logic of the renovation.

The main residence offers a flexible, well-balanced layout with three bedrooms and two bathrooms, where the thoughtful separation of spaces works as well for daily family life as for entertaining. Interiors are bright and airy, with clean finishes that feel both modern and enduring. Views of Tennessee Valley frame the backdrop of daily life throughout.

The detached fourth bedroom: A separate structure with its own full bath — ideal as a guest suite with genuine privacy, a home office with complete separation, or a creative studio. In Mill Valley, where the combination of a large level lot and an independent ancillary structure is genuinely rare, this adds a functional dimension that the standard single-family floor plan simply cannot deliver.

We listed and sold 333 Richardson Way. Closed at $2,887,000 — $1,352 per square foot — against a list price of $2,595,000, representing an 11% over-asking result.
