    What's special

    Vapor fireplaceAdvanced mechanical infrastructureDedicated officeCustom millworkFully equipped summer kitchenMultiple covered terracesFull-home sound system
    A rare dual-offering on coveted Millionaire's Row in Tavernier, this extraordinary oceanfront compound spans over multiple acres across two parcels-delivering an unmatched combination of scale, privacy, and future development flexibility in the Florida Keys. At 88845, a newly constructed 8,200SF estate sets a new standard for modern coastal luxury. Thoughtfully designed for both grand entertaining and private retreat, the residence offers 5 bedrooms, 6 full baths & 2 half baths, complemented by a dedicated office, control room, mudroom, and expansive 3-car garage with climate-controlled workshop. Interior finishes are curated at the highest level, including white diamond marble, teak wood flooring, custom millwork & a vapor fireplace, while a full-home sound system, elevator & advanced mechanical infrastructure provide seamless functionality. The chef's kitchen is equipped with top-tier Wolf, SubZero, & Cove appliances, dual dishwashers, farmhouse sinks, refrigerated drawers, wine storage & custom mahogany countertops-designed to accommodate both everyday living and large-scale entertaining. Outdoor living is equally impressive, anchored by a 120-foot resort-style pool with integrated spa, heating & chilling systems, & full smart control. A fully equipped summer kitchen, cabana bath, & multiple covered terraces create a true waterfront lifestyle experience. With 480 feet of water frontage, the protected basin offers exceptional boating capabilities, including 90 feet of dockage & room to expand, a 20,000lb lift, boat ramp & deep-water access. The adjacent parcel at 88835 provides over 3 acres of additional opportunity featuring a renovated 3-bedroom residence completed in 2022, with a transferable TDR allowing for the development of a substantially larger primary home. The property also includes a buildable lot & natural hammock buffer for added privacy. Together, these two properties present a generational opportunity to own a one of a kind waterfront compound.
