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.

Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Douglas Elliman Real Estate.
The upper level holds the living and dining area, an open kitchen, and a full bathroom with a jacuzzi tub, and the listing notes the layout could be opened up further for a larger entertaining space. Downstairs, the renovated lower level sits under a full-width skylight, which the listing says floods it with natural light. That's the room that does the most work, since the listing suggests it for a primary suite, media room, home office, gym, or guest space, and it's where I'd start planning.
The skylight has solar-powered blackout shades and opens electronically for fresh air. A rain sensor closes it automatically when needed, which matters on a skylight you won't be checking by hand. An insulated subfloor, two storage closets, and a powder room complete the level.
Out back, the garden measures approximately 410 square feet and is half stone tiling, half all-season turf. The listing describes it as getting strong sun through the day, which suits dining or gardening. In the city, a private garden of this size is a real amenity, though drainage, upkeep, and access shape how usable it is day to day.
The home has zoned heating and cooling, LED lighting, hardwired Ethernet in every room, smart lighting controls, and a smart entry lock. The washer and dryer are new and in the unit, and the kitchen has a brand new KitchenAid dishwasher.
The R train at 25 St is about 11 minutes on foot, and Detective Joseph Mayrose Park is about 6 minutes away. Giuseppina's, Southside Coffee, and Battle Hill Tavern are each within about 6 minutes on foot. The listing also notes a park view.
It's a condominium, so ownership works differently from a co-op, though building rules and expenses still need review. Pets are allowed with board approval.
