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.
