275 Walnut Street in Eastside Costa Mesa offers this New Construction 2025 home thoughtfully designed and lovingly crafted. This tree-lined block is a favorite in Eastside, with proximity to excellent public and private schools, parks and libraries, and of course the amazing retail and conveniences of 17th Street and PCH, and the nature and open space of Newport's Back Bay. The home is approx. 3,271 SF with 5 bedrooms (4th staged as bonus room), plus an office, indoor laundry, HUGE walk-in pantry, and mud room. A fantastic kitchen with island offers Thermador appliances with cabinet facing, a separate refrigerator and freezer, double oven, 6-burner gas range with griddle, custom hood, and pot filler. Downstairs includes a guest bedroom with en suite bath, study/salon/music room, and open concept living, dining, and kitchen great room. Upstairs houses the primary suite, plus 3 additional bedrooms, and laundry. A 3-car garage lies off the alley, a separate bay with air-conditioned space that could function as a gym, additional office, craft or bonus room. The lower level opens to the yard via La Cantina style doors. A highly amenitized backyard connects the home and garage, including a built-in BBQ and beverage center with TV, fire pit, hanging swing and covered porch, plus lounging and dining areas. Inside spaces are flooded with natural light that dances amidst the high volume ceilings. This flexible floor plan can accommodate a growing household and/or provide many options for work and leisure. Tasteful yet practical and elegant finishes lend themselves to luxury living that suits our coastal Orange County lifestyle. 275 Walnut is a must see opportunity for those who enjoy new homes of quality craftsmanship.
