Property Description

Extensively remodeled in 2021, this exceptional Balboa Peninsula duplex blends refined coastal design with thoughtful modern living just moments from the sand, bay, and Marina Park. Striking coastal-modern architecture showcases crisp white brick, expansive glass, custom steel bifold doors, black metal accents, warm wood detailing, and casement windows thoughtfully designed to maximize natural light and ocean breezes throughout. Inside, both residences feature 9-inch-wide DuChâteau Atelier hardwood flooring, custom beadboard and wainscoting, Serena & Lily wallpaper accents, custom built-ins, and designer lighting. The lower residence offers two bedrooms and two full bathrooms, while the upper residence features three bedrooms, two full bathrooms, and a spacious covered entertaining deck complete with custom shade structure, gas and water hookups, and seamless indoor-outdoor flow. Multiple fireplaces, custom media cabinetry, motorized Hunter Douglas shades, integrated smart home features, and custom built-in elements further elevate the living experience throughout both units. Both kitchen and bath spaces have been extensively customized with premium finishes and designer materials, including Thermador appliances, quartzite and quartz countertops, handcrafted zellige tile, Rohl and Hansgrohe fixtures, Toto toilets, custom vanities, and curated selections from Walker Zanger, Tabarka Studio, Artistic Tile, and Mosaic House. Additional highlights include separate LG mini-split HVAC systems with individualized climate control throughout living spaces and bedrooms, Kolbe windows and doors throughout, integrated security and leak detection systems, EV charging infrastructure, an attached two-car garage with epoxy flooring and custom cabinetry, and a covered three-car carport — an exceptionally rare amenity on the Peninsula. Located moments from the beach, bayfront recreation, the Fun Zone, local cafés, restaurants, and waterfront activities, this exceptional property offers a rare combination of lifestyle, versatility, and long-term value in one of Newport Beach’s most desirable coastal communities. Whether envisioned as a refined owner-user residence with supplemental income potential, a multi-generational beach retreat, or a turnkey investment opportunity, this extensively remodeled duplex captures the essence of elevated Peninsula living.
