Rare Opportunity on Balboa Island –

Just off Marine Avenue, this nearly new residence sits on an oversized, premium lot and redefines modern coastal living. Large windows frame island views throughout, filling the home with natural light and blurring the line between indoor and outdoor space.

The residence offers four en suite bedrooms, two additional powder rooms, and a layout built for both everyday living and effortless entertaining. The gourmet kitchen pairs premium appliances with refined finishes and opens to an inviting interior courtyard — a rare architectural touch that brings even more light and air into the home’s center. Upstairs, the rooftop deck delivers island and water views alongside a fireplace, built-in BBQ, and outdoor TV — an entertainer’s dream setting for sunset gatherings. The primary suite is a true retreat, with soaring ceilings and an expensive walk-in closet.

Thoughtful details set this home apart: solar power, a private elevator servicing all three levels, an outdoor shower, EV charger, and a rare three-car garage — a coveted convenience on the island.

Moments from Newport’s famous beaches, Lido Island, Fashion Island, and John Wayne Airport, this is a rare chance to own one of Balboa Island’s finest residences, with easy access to water sports, world-class shopping, and fine dining.
