About 50 Birch St

Come home to comfortable California living in this New Construction home designed by the renowned Hatfield Architecture. Located just above the festivities of downtown, stately redwoods, oaks, and pines tower over the newly landscaped .36-acre lot (16,100 sq. ft.), creating a sense of privacy and natural beauty. The contemporary floor plan flows effortlessly inside and out, setting a tone of ease from the moment you arrive. This home offers 3,921 sq. ft. of living space across a 4-bedroom, 4.5-bath main residence plus an attached studio ADU with its own private entrance and covered parking. Enter the great room with soaring vaulted ceilings, where floor-to-ceiling windows and folding glass doors open to a generous deck with stunning hillside views. The gourmet kitchen anchors the space with a massive quartzite natural stone center island, dual beverage and veggie fridges, and top-tier Monogram appliances including a 6-burner gas range, double wall ovens, and a full-size refrigerator/freezer. The primary bedroom shares the same sweeping views on the main floor. An upstairs office or guest room adds flexibility. Downstairs, there are three ensuite bedrooms. The studio ADU opens directly to the patio and turf lawn. For added convenience, each floor has its own laundry room. The upper is equipped with a grey-water system ready to be converted for irrigation use. White oak engineered hardwood floors run throughout, and Enphase rooftop solar takes full advantage of the home's sunny hillside exposure. Located minutes from excellent schools, parks, and the restaurants and cafes of historic downtown, 50 Birch St. comes with easy access to San Francisco, Stinson Beach, Muir Woods, Point Reyes Station, and Sonoma and Napa Wine Country.
