A rare dual-parcel offering on prestigious Millionaire’s Row in Tavernier, 88835 and 88845 Old Highway present an extraordinary opportunity to own one of the Upper Keys’ most expansive and versatile oceanfront compounds. Spanning multiple acres with 480 feet of waterfrontage, the property combines exceptional privacy, premier boating access, and remarkable future development potential. At 88845 Old Highway, a newly constructed 8,200 SF modern estate showcases 5 bedrooms, 6 full baths, 2 half baths, designer finishes, smart-home technology, a resort-style 120-foot pool, and a protected basin with dockage, boat lift, and deep-water access.
