About This Home
Nestled on one of South Slope's most picturesque, tree-lined blocks, this thoughtfully updated duplex offers the privacy and outdoor space of a townhouse with the ease and convenience of condominium living. The upper level is currently configured as a spacious one-bedroom residence, featuring an inviting living and dining area, an open kitchen, and a well-appointed full bathroom complete with a jacuzzi tub. The layout also presents an opportunity to further open the living space, creating an even more expansive entertaining area. Downstairs, a beautifully renovated lower level dramatically expands the home's functionality. Flooded with natural light from a full-width skylight, this versatile space is ideal as a primary suite, media room, home office, gym, guest suite, or additional sleeping area. The skylight is equipped with solar-powered automatic blackout shades and opens electronically to allow fresh air inside, while an integrated rain sensor provides peace of mind by closing it automatically when needed. An insulated subfloor ensures year-round comfort, and two generous storage closets, along with a convenient powder room, complete this level. Just beyond, your private backyard becomes a true extension of the home. Measuring approximately 410 square feet, the garden is half stone tiling, half all-season turf, and enjoys exceptional sunlight throughout the day-perfect for outdoor dining, gardening, entertaining, or simply unwinding in your own peaceful retreat. The home has been extensively upgraded for modern living, including individually zoned heating and cooling, LED lighting throughout, hardwired Ethernet in every room, smart lighting controls, a smart entry lock, a new in-unit washer and dryer, and brand new Kitchen Aid dishwasher. Residents enjoy the benefits of a 25-year tax abatement, exceptionally low monthly carrying costs, and bike storage within this well-maintained condominium. Perfectly positioned between Greenwood Heights, Park Slope, and Windsor Terrace, the location offers the best of Brooklyn living. Zoned for PS 10 and moments from the F and R trains, you'll also find neighborhood favorites including Giuseppina's, Southside Coffee, Folk, Greenwood Park Beer Garden, and Battle Hill Tavern just around the corner.
