21 Lefferts Place is a four-story, six-condo new building on a leafy Clinton Hill block between St. James Place and Grand Avenue. I love this block because it's tucked away from the chaos of Fulton and Atlantic, yet still convenient to the subway. Five homes have sold, and the last one is the garden duplex with a private yard.
Where Things Stand
The Attorney General accepted the offering plan on October 7, 2025, and sales launched on November 18, 2025, about six weeks later. As of November 1, 2026, five of the six homes have sold and closed, and the garden duplex is the only one available. It first listed in March at $1,850,000 and has been back on the market since September 29 at $1,800,000.

Buying in a New Development?
New construction works differently than a resale: offering plans, sponsor contracts, closing costs and timelines all have their own rules.
A Closer Look at the Building
This is a small walk-up with six homes, built on what used to be a vacant lot, with a facade that sits comfortably among the brownstones. Lefferts Place is part of the Clinton Hill South Historic District. Inside, the homes have wide-plank oak floors, warm wood and matte kitchen cabinetry with stone counters and integrated appliances, large-format stone tile in the baths and an in-unit washer and dryer.
The garden duplex is a full floor-through with southern light in the living and dining room and both bedrooms at the quiet rear, overlooking the yard. Downstairs is a separate recreation or media room with a powder room, which works as an office, gym or playroom. The yard opens straight off the main level and mixes patio and planting areas.

Clinton Hill Highlights
Clinton Hill mixes the residential feel of brownstone Brooklyn with the energy of Pratt Institute, and BAM and Fort Greene right next door. Mansion blocks on Clinton and Washington Avenues sit next to small new condos, and the neighborhood is small enough to feel like a real community. Cafes and bakeries like Smør, Otway and Hartley's are close by.

Katie's Take
I track every new development in Brooklyn, and here's how this one compares: 21 Lefferts Place has averaged about $1,430 a square foot, a bit below the roughly $1,510 that 755 Washington Avenue sold out at and above the roughly $1,300 at 124 Washington Avenue. The garden duplex is asking about $1,150 a square foot, the lowest in the building, because a good share of its space is on the lower level. If a private yard of more than 800 square feet in Clinton Hill for under $2M is on your list, this is the one to see before the building is done.
