Property Description
Among California’s most distinctive waterfront residences, this iconic Mid-Century Modern estate on Naples Island stands as both an architectural treasure and a piece of Long Beach history. Designed by acclaimed architect George M. Montierth, the home was originally commissioned as an executive retreat, created to entertain corporate guests drawn to Long Beach during the city’s thriving mid-century era. Its grand scale, dramatic design, and commanding waterfront presence reflect that legacy of hospitality and prestige.
Perfectly sited at the convergence of Naples Canal, Rivo Alto Canal, and The Colonnade Canal, the residence captures sweeping views of Alamitos Bay and The Peninsula from one of the island’s most sought-after locations. A private marina spans 135 feet of open-water frontage and includes a 35-foot U-shaped slip with a 13-foot beam—an extraordinary amenity for yachtsmen and water enthusiasts alike.
The 6,182-square-foot home is centered around a serene courtyard with a swimming pool, offering seamless indoor-outdoor living. A soaring 20-foot entry sets the stage for dramatic entertaining, leading to a paneled formal living room with marble fireplace and walls of glass overlooking the water. A full walk-in wet bar, elegant dining room, and expansive gathering spaces recall the home’s original purpose as a setting for distinguished entertaining.
Two generous primary suites provide luxurious retreats—one with its own marble fireplace—both with walk-in closets, vanity rooms, and spa-inspired baths. Additional highlights include a private guest house with full bath, a workshop, and a motor court accommodating up to 6 cars.
Positioned across five legal lots, including three waterfront parcels, the estate offers 112 feet of water frontage and exceptional versatility. Whether preserved as a Mid-Century showpiece, reimagined as a contemporary masterpiece, or developed anew, it represents one of the rarest opportunities on Naples Islands. Recent updates include a new roof, fresh paint, resurfaced upper deck, and a newly completed seawall, ensuring both beauty and structural integrity for years to come.
A true legacy estate, this home embodies the elegance of its mid-century origins while offering unmatched potential on one of Southern California’s most prestigious waterfronts.
