Introducing the Sea Pearl: a rare and refined coastal masterpiece nestled on Lower Matecumbe, just four parcels from the Gulf of Mexico. This ultra-modern smart home, constructed in 2016 redefines luxury Keys living, offering five spacious bedrooms, five and a half bathrooms, and over 4,100 square feet of meticulously designed and furnished interior space. Boaters will delight in 70 feet of concrete dockage with water and electric, a 15,000 lb boat lift, and panoramic sunset views over a protected nature preserve across the canal—ensuring privacy and tranquility that can never be built upon. This concrete haven is fully equipped with a whole-home generator, Control4 smart system (for AC, music, lights, alarm, security cameras, TV's and more), impact windows/doors, metal roof, and a sleek glass elevator connecting all three levels. Nearly 1,500 square feet of open-air porches and patios invite you to unwind and soak in the Gulf breezes. Step inside the ground level to a welcoming foyer that opens to a sitting area, custom wet bar, Angler's room, and guest ensuite bedroom. Just beyond, enjoy a resort-style pool and built-in spa surrounded by shell stone decking that stays cool even in the height of summer. On the second level, a show-stopping modern kitchen features custom cabinetry, Brittanica Cambria quartz countertops, expansive island with waterfall edge, seating for 8, GE Monogram appliances, Viking 6-burner induction cooktop, and wine cooler—perfect for entertaining. This level also offers three additional bedrooms, including a Jack-and-Jill suite, full laundry, and half bath. The entire top floor is reserved for the primary suite: a true sanctuary with sweeping water views and an open-air porch, spa-like bathroom with soaking tub, glass shower, bidet, and a custom walk-in closet. With optional White Marlin Beach access, this home is the epitome of modern island elegance—where every detail has been curated for comfort, style, and the ultimate Florida Keys lifestyle.
