A rare opportunity to secure a custom-designed coastal estate just steps from Newport Beach’s Back Bay, positioned on a quiet cul-de-sac in one of the area’s most sought-after enclaves. Currently in advanced stages of construction, this 5-bedroom, 5-bathroom residence will span approximately 3,983 square feet, designed by LL Design and built by Well Done Building & Design. The home is anchored by a dramatic great room with ceilings exceeding 20 feet, creating exceptional volume, natural light, and a striking architectural presence. Expansive windows capture peek-a-boo views of the Back Bay and surrounding mountains, bringing the outdoors into the core of the home. The layout is both functional and refined, featuring a designer kitchen with custom cabinetry, premium appliances, and curated finishes that seamlessly connect to the main living and dining spaces. Thoughtful architectural details, including built-ins and layered materials, add depth and continuity throughout. Upstairs, the primary suite is designed as a private retreat with generous scale, natural light, and a spa-inspired bath. Secondary bedrooms are well-appointed, each offering comfort, privacy, and cohesive design. Situated just moments from the Back Bay’s scenic trails, this home offers a rare combination of scale, design pedigree, and premier positioning — with the opportunity to step into a nearly completed custom build in one of Newport Beach’s most desirable locations.
