Set into the hillside with open outlooks to town and iconic redwoods, 169 Rose Avenue is a modern retreat with rare scale, light, and untapped potential in Mill Valley. Spanning over 3,600 square feet with four bedrooms and three and a half bathrooms including a legal ADU, the home balances volume with privacy. Tucked among the trees and wrapped in quiet, it captures what people move here for. The main living spaces open beneath high atrium ceilings, with walls of glass bringing in light and views of redwoods and into town. Radiant-heated hardwood floors run throughout. Decks span the top two levels, extending living outdoors for dining, lounging, and entertaining. A lower outdoor level would make a perfect lounge, at-home spa, or turfed play space for kids. The kitchen anchors the home with two large islands, custom wood cabinetry, stone countertops, paneled appliances, and a La Cornue range, flowing easily into the dining and living room with gas fireplace. The bedroom level is calm and generous, with high ceilings, solid wood doors, and direct access to wraparound balconies. Laundry and thoughtful storage are conveniently located on this level. A fully legal one-bedroom ADU with its own living room, kitchenette, walk-in closet, and full bathroom with laundry offers flexibility for guests, family, or income. A two-car garage, two additional rooms for an office, gym, or studio, ample storage, and elevator access to all levels complete the home. Backyard access to the Mill Valley trail system with neighborhood staircases that drop into downtown, 169 Rose is meant for the outdoor enthusiast who also wants a home worth coming back to. Architecture-forward, quality bones, and room to make it unmistakably yours. A forever kind of home, and a must-see in person.
