Eight New Condos Planned for 21 Denton Place in Gowanus

Nov 2

21 Denton Place is a new eight-unit condo building planned for a quiet lane in Gowanus, just off 4th Avenue between Carroll and 1st Streets, right where Gowanus meets Park Slope. It's a short walk to Washington Park and the Old Stone House, Whole Foods on 3rd Street and the Park Slope Food Coop. The sponsor team is also behind the 66-unit rental at 288 4th Avenue on the same block.

Where Things Stand

The offering plan for 21 Denton Place was submitted to the New York State Attorney General on August 26, 2026, and is awaiting acceptance. No units are for sale yet, there is no public pricing, and reservations can't be taken. Across the 53 Brooklyn projects I've tracked from filing to acceptance, most were accepted 5 to 9 months after filing (about 7 months is typical), which points to acceptance between roughly late January and late May 2027. Join my early access list below and you'll hear about pricing and launch timing before it reaches StreetEasy.

What We Know So Far

Eight condos in a new four-story building with a cellar and ground-floor commercial space
About 10,570 square feet of total floor area in the DOB filing, or roughly 1,320 square feet of building per home; that total includes the commercial space, so the homes themselves will be somewhat smaller
Likely two homes per floor in a mix of two- and three-bedroom layouts (the final mix isn't public yet)
Offering plan filed: August 26, 2026
What's next: Attorney General review typically takes several months, and pricing becomes public once the plan is accepted

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

With eight homes, 21 Denton Place has the scale of a brownstone block with the benefits of new construction: modern systems, modern layouts and the chance to be the first owner of your home. Small condo buildings are still rare in this part of Gowanus, since most of the new supply after the 2021 rezoning has been large rentals. Pricing, common charges and the final unit mix will be public once the plan is accepted.

Gowanus Highlights

Gowanus is one of Brooklyn's fastest-changing neighborhoods since the 2021 rezoning, and Denton Place sits on its quiet eastern edge, a block from Park Slope. You're close to 5th Avenue's restaurants, the canal's breweries and studios, and Whole Foods on 3rd Street.

The R at Union Street, about a 4-minute walk
The F, G and R at 4th Avenue-9th Street, about 10 minutes
Washington Park, J.J. Byrne Playground and the Old Stone House, about 4 minutes

Katie's Take

I track every new development filing in Brooklyn, and this one stands out because it's one of only two condo filings I'm following in Gowanus, alongside 160 12th Street, and the only one tucked a block from Park Slope's north end near Washington Park. Both are small ground-up buildings sized for two- and three-bedroom homes, a contrast to the large rentals that make up most new Gowanus construction. The one Gowanus condo selling now, 100 16th Street, has sold or gone into contract on three of its four homes at about $1,150 a square foot, so that's a useful floor to keep in mind when pricing here comes out, most likely in the first half of 2027.
