4 Florence Avenue Private Waterfront Estate with Marina, Triple Lot & Expansive Outdoor Living A rare waterfront opportunity in the tucked-away Gerritsen Beach community. This sun-filled private estate sits on a triple lot and offers the kind of space, privacy, and waterfront lifestyle that is extremely hard to find in Brooklyn. The home features 4 bedrooms, 3 full bathrooms, plus 2 additional flexible rooms that can be used for recreation, home offices, fitness, or other lifestyle needs. Inside, the home has been beautifully renovated with dark hardwood floors, custom crown moldings, generous closet space, and a spacious open layout designed for comfortable everyday living and entertaining. The oversized living and dining areas enjoy open waterfront views, while the professional chef's kitchen features granite countertops, high-end cabinetry, and high-quality finishes. The outdoor space is what truly separates this property from the rest. Sliding glass doors lead to an impressive 1, 200 sq ft TREX wraparound two-tier deck, creating the perfect setting for large gatherings, summer parties, outdoor dining, and peaceful waterfront relaxation. The property also features new pavers, a swim spa pool, garden area, and over 2, 500 sq ft of private waterfront outdoor space. The crown jewel of the estate is the private 16-foot boat slip with its own meter, water, and electric. The all-new marina can be enjoyed privately or may offer possible income-producing potential, subject to applicable rules and approvals. Additional highlights include an indoor gym area, three separate private entrances, a sprawling backyard, and a quiet block location. A true waterfront compound offering privacy, space, lifestyle, and flexibility. An absolute must-see.
