Ocean views, sparkling city lights, and the opportunity to create a custom coastal retreat await at 10 Narbonne in Newport Beach's prestigious Harbor Ridge community. The existing four-bedroom, four-bath residence offers over 4,000 square feet of living space, complemented by architectural plans that envision a substantial remodel and expansion with a separate ADU. The proposed design calls for approximately 5,261 square feet of living space in the main residence plus an approximately 1,036-square-foot detached ADU, for a combined approximately 6,297 square feet of proposed living space, excluding the garage. Thoughtfully reimagined for modern living, the main home's proposed layout features four upstairs bedrooms, each with an en-suite bath, a dedicated first-floor office, an upstairs loft, and a spacious primary retreat with a generous walk-in closet and access to an outdoor terrace. Open living and dining areas connect to an expansive island kitchen, complemented by a separate wok kitchen and large pantry. Additional planned features include laundry rooms on both levels and a three-car garage. The proposed ADU includes a bedroom, a separate guest room, a bathroom, a kitchen, and living and dining areas, offering additional flexibility for extended family and visiting guests.
