Perched above Richardson Bay, this newly reimagined residence is more than a home, it's a modern retreat designed for inspired living. Rebuilt from the ground up with interiors by The Workroom, every detail reflects a rare blend of artistry and intention. The sunlit great room makes a dramatic first impression with soaring ceilings, an Ortal fireplace, and walls of glass that frame the bay views. The chef's kitchen blends warm custom millwork with Calacatta marble countertops and a generous island for gathering. The space flows into a spacious living area and a cozy breakfast nook with a built-in banquette. The main level hosts 3 bedrooms and 2 baths, including a luxurious primary suite with panoramic water views and a spa-inspired bathroom. On the lower level, a versatile family room flows to the outdoors with new La Cantina sliders. A sleek kitchenette with a wet bar makes entertaining effortless. Two bedrooms, a remodeled bath, and a laundry room complete this floor. The outdoor spaces offer multiple destinations for relaxation and play: a flat grassy lawn, a private patio with in-ground hot tub, and space for a future pool or ADU to create a compound. Set in a tranquil, private location, this home invites connection, relaxation, and is just minutes from downtown Mill Valley.
