An exceptional opportunity for an owner-user in the highly sought-after coastal enclave of Sunset Park, Santa Monica. The offering includes a 6,402 square foot lot and fully approved RTI (Ready-To-Issue) architectural plans so construction can begin immediately on a thoughtfully designed approximately 3,400 square foot two-story residence with an approximately 600 square foot detached guest house/ADU (approximate total of 4,000 square feet). The seller is an experienced local general contractor who has built several beautiful homes in the surrounding neighborhood, bringing valuable insight to the design, efficiency, and planning of this project. (Approximate cost to build is $600 per square foot.). The architectural plans envision a sophisticated main residence with an attached two-car garage and a flexible open-concept floor plan tailored for modern indoor outdoor California living. The main level offers an airy layout that includes formal living and dining areas, along with an expansive family room that seamlessly connects to a chef's kitchen with a center island and walk-in pantry. Designed for effortless entertaining, the living spaces flow naturally to a private resort-style backyard retreat featuring a large turf lawn, swimming pool, spa, and generous outdoor entertaining areas. The setting is ideal for al fresco dining, relaxing in the sun, and enjoying cool ocean breezes. A main-level Jr. ADU with its own private entrance offers versatility and can function as a first-floor bedroom suite, guest quarters, media room, or private office. Toward the front of the home, a mudroom and powder room are conveniently located adjacent to the direct-access two-car garage. Upstairs, the expansive primary suite serves as a luxurious retreat with a balcony, a spa-inspired bathroom featuring a separate soaking tub and shower, and dual walk-in closets. Two additional bedroom suites, a centrally located laundry room, and a spacious flex area ideal for an upstairs family lounge complete the second level. At the rear of the property, the detached guest house/ADU features a comfortable living area, kitchen, bathroom, and laundry. The space is ideal for guests, extended family, rental income, a pool house, gym, art studio, or a dedicated home office. Sunset Park is one of Santa Monica's most charming and desirable neighborhoods, known for its vibrant sense of community and relaxed coastal lifestyle. The property is just moments from boutique shopping, cafes, and acclaimed restaurants along Ocean Park Boulevard and the popular Main Street district. Residents enjoy easy access to the beach, scenic bike paths, the beloved local farmers markets, neighborhood parks, and some of the Westside's most highly regarded schools. Finished new construction homes in this specific part of Santa Monica range in price up to $5,500,000. This is an exceptional value add sale.
