6425 Pine Avenue Architecture, nature and island living come together in a home unlike anything else on Sanibel. Designed and originally built by renowned architect Kevin Farrell as his own family residence, this one-of-a-kind contemporary retreat was created around natural light, privacy and a seamless connection between indoors and out. Farrell's work includes the Sanibel Causeway, adding a special architectural pedigree to a home that truly must be experienced. Tucked into the quiet Del Sega community, just minutes from the heart of Captiva, this 4-bedroom, 3-bath home is surrounded by lush native landscaping on more than half an acre. Soaring ceilings, walls of glass and expansive windows bring the tropical surroundings inside while maintaining remarkable privacy. Then there is the pool. More private resort than backyard, this extraordinary outdoor oasis is centered around a large custom pool with sun shelf, hand-laid mosaic details and a poolside palapa with cascading rooftop waterfall. Spend afternoons by the water, dine beneath the palms or enjoy the newly screened no-see-um patio. A pool bath and outdoor shower complete the experience. The primary suite is its own private escape with sitting area and balcony offering a peek-a-boo Gulf view. When sunset approaches, one of Southwest Florida's most beautiful beaches is just yards away; close enough to make an evening walk to the Gulf part of everyday life. The expansive garage is another rarity, with front, rear and side access plus exceptional storage and flexibility for vehicles, an RV, boat, water toys, workshop or collector-car storage. Multiple driveways add even more versatility. Recent improvements include a 2024 aluminum standing-seam roof with 30-year warranty, 2026 Trane HVAC, new pool heater and equipment, upgraded 200-amp electrical panel with generator connection, irrigation, landscaping, interior/exterior paint, gutters and more. Deeded beach access and a neighborhood boat ramp put both the Gulf and bay within easy reach, while Captiva's dining and island lifestyle are just minutes away. In a setting that feels worlds away from everything, this is more than a distinctive Sanibel home; it is an architectural island retreat that would be nearly impossible to recreate today.
