Located in the heart of Old Town, this truly magical estate presents an opportunity to own a private compound of remarkable scale and architectural distinction. Set on an oversized lot with off-street parking for two, the property features two fully independent residences--each appointed with impact-rated windows and doors. Situated along iconic Millionaire's Row, the main residence is a masterfully restored historic home that pays homage to its original character while embracing today's highest standards of luxury and comfort. Offering four spacious ensuite bedrooms, the main home includes a versatile first-floor suite that can easily function as a first floor primary bedroom or den. Additional features include original Dade County pine walls, reclaimed river wood flooring, soaring ceilings, and generous windows that bathe the interiors in natural light. At the heart of the home lies a chef-caliber gourmet kitchen with custom cabinetry, Sub-Zero and Wolf appliances, sculpted marble countertops, a built-in wine cooler and dedicated coffee center. French doors open to the wraparound porches- offering an idyllic setting for morning coffee, sunset cocktails, or alfresco dining. The estate's newly constructed guest house features two additional ensuite bedrooms, dramatic vaulted ceilings, and a charming loft ideal for additional living. The fully equipped kitchen features high-end Miele appliances and striking artisan tile. Anchoring the property is an extraordinary outdoor living environment conceived by renowned landscape architect Craig Reynolds. This lush, resort-style sanctuary showcases a sparkling saline swimming pool, cascading waterfall, outdoor shower, and a discreet poolside half bath. 1109 Fleming is more than a residence--it is a landmark Old Town estate equally suited for full-time living, a refined second home, or a legacy property to be enjoyed for generations on one of Key West's most prestigious streets.
