An Estate Designed to Feel Like Your Own Private Island Retreat. Etched-glass entry doors and a soaring two-story foyer crowned by a striking cupola introduces a residence defined by timeless architecture, exceptional craftsmanship, and grand scale. Rich ceiling treatments, custom lighting, an integrated Sonos sound system, and refined finishes carry throughout the home. The Great Room is crowned by a dramatic octagonal coffered lantern ceiling with warm Bahama-inspired wood louvers, a fireplace, and zero-corner pocketing sliding glass doors that create a seamless transition to the waterfront lanai. At the heart of the home, the chef's kitchen blends beauty and function with striking stone countertops and backsplash, illuminated custom cabinetry, premium JennAir appliances, a six-burner gas range, oversized island with breakfast bar, casual dining, and generous space for entertaining. An executive office with multiple workstations provides an ideal study or den. The first-floor primary suite is a sanctuary overlooking the water, with custom walk-in closets, wet bar, adjoining fitness room, and a spa-inspired bath featuring a distinctive elevated jetted soaking tub, cosmetic vanity, and an oversized walk-in shower. A private first-floor guest suite offers exceptional comfort for visitors. Upstairs, two additional ensuite guest bedrooms--including one thoughtfully designed as a private home theater with its own fireplace--open to a waterfront balcony that captures the long-water views. Outside, Bahama-inspired louvered ceilings extend across the expansive covered lanai, where generous lounge and dining areas create an exceptional setting for waterfront entertaining. The impressive outdoor kitchen features a built-in grill, dedicated cooking area, seated bar, refrigerator, sink, and abundant serving space for effortless gatherings. Towering palms and lush tropical landscaping frame the saltwater pool, cascading waterfall spa, with outdoor fireplace, pool bath, and sweeping waterfront views, creating an atmosphere of privacy and island elegance. Both the main lanai and upper balcony are fully screened, allowing year-round enjoyment of Southwest Florida's coastal climate. A dramatic spiral staircase leads to the a rooftop terrace (new roof in 2025), where commanding Gulf views provide an unforgettable backdrop for spectacular sunsets. Completing this exceptional estate are a 38kW whole-home generator, a 1,000-gallon propane tank, 2 new A/C units 2026, re-roof in 2025, and an oversized three-car garage. The rare oversized fenced side yard provides valuable street-to-water access, making it easy to transport paddleboards, kayaks, watercraft, and boating gear to the composite dock with dual boat lifts (35,000 lb and 20,000 lb), a fish-cleaning station, dock lighting, water, and electric. From there, Marco Island's extraordinary waterways and the Gulf become an extension of your backyard, defining the quintessential Southwest Florida waterfront lifestyle.
