Turnkey Windsor Terrace House Just steps from Prospect Park, this beautifully renovated single-family home blends classic Brooklyn charm with modern upgrades and a sun-filled, oversized backyard - ideal for entertaining, gardening, or relaxing outdoors. The double parlor at the front of the home is bathed in natural light from four bay windows. Original oak columns and arched doorways preserve historic character, while new white oak floors on the first level and refinished pine floors upstairs, including the staircase, add warmth and elegance. Thoughtful touches such as custom entry cabinetry and a window seat with drawers in the living room provide both charm and practical storage. The adjoining dining room flows seamlessly into a bright, renovated kitchen featuring Caesarstone countertops, a farmhouse sink, a large seating island, and cheerful blue tile backsplash. Stainless steel appliances include a Bosch dishwasher, LG refrigerator, and new GE range. A custom pantry with soft-close pullouts, a stylish half bath, and in-unit laundry complete the level. Upstairs, three bedrooms and a renovated full bath with a clawfoot tub, slate flooring, and subway tile provide comfort and sophistication. The primary suite features four bay windows, a generous closet, and an adjoining room ideal for a home office, nursery, or dressing area. Two additional bedrooms are bright, versatile, and inviting. Dual-zone Mitsubishi mini splits provide year-round comfort, and certified lead abatement throughout the home ensures peace of mind.
