    Set on over 2 acres along prestigious Millionaire's Row in Tavernier, this newly constructed oceanfront estate represents a rare convergence of scale, design, and functionality in the Upper Florida Keys. Encompassing 8,200 square feet of interior living space and over 16,000 square feet total, the residence is thoughtfully designed to accommodate both elevated everyday living and large-scale entertaining.The home features 5 bedrooms, 6 full baths, and 2 half baths, with all bedrooms offering en suite accommodations, custom closet build-outs, and refined finishes throughout. Additional interior spaces include a dedicated office, control room, mud room, and laundry room, providing both comfort and operational efficiency. A private elevator, whole-home sound system, and advanced mechanical infrastructure--including 600-amp service, multiple electrical panels, and five independent AC zones--underscore the property's level of detail and performance. Interior finishes are curated with a modern coastal aesthetic, highlighted by white diamond marble and teak wood flooring & a custom steel roof. The chef's kitchen is outfitted with top-tier Wolf, SubZero, and Cove appliances, including a 60-inch range, dual dishwashers, farmhouse sinks, and custom mahogany countertops--designed to seamlessly blend form and function. Outdoor living is equally exceptional, with 240 feet of oceanfront, anchored by a 120-foot resort-style pool, complete with multiple heating and chilling systems, a gas-heated spa, and full smart control. A fully equipped summer kitchen, cabana bath, and multiple covered entertaining areas create a true indoor-outdoor lifestyle experience. Additional highlights include a 3-car garage and fully equipped workshop with air conditioning, utilities, security systems, and custom lighting. The property is also zoned for weekly rentals, presenting a compelling opportunity for both personal enjoyment and income potential.
