Now Selling: Eight Condos at 515 Dean Street in Prospect Heights

Now Selling

Nov 1

515 Dean Street is a former church converted into eight condos in Prospect Heights, two minutes from the Bergen Street 2 and 3. Every home is a three-bedroom, two-and-a-half-bath with its own private outdoor space, which is a rare mix in a building this size.

Where Things Stand

The Attorney General accepted the offering plan on April 1, 2026, and sales launched on September 8. As of November 1, 2026, three homes are in contract (one of them on the day it listed), two more are available, and three, including both garden homes, haven't been publicly listed yet. When I first wrote about this building I said I'd expect these three-bedrooms to sell quickly, and so far they have. Join my early access list below and you'll hear when the garden homes list, before they reach StreetEasy.

The Numbers So Far

As of November 1, 2026, from the public listings:

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

Because this was a church, the building has about ten and a half feet from floor to floor, so the ceilings feel tall in a way you rarely find in a small building. The homes run from 1,530 to 1,554 square feet, two per floor around a central elevator. The two ground-floor homes have private yards, one of them roughly 2,000 square feet, larger than the apartment itself, and the upper floors have private terraces or balconies.

Every home also comes with its own private room in the cellar, set around a shared lounge, which the sponsor will finish as an office, playroom or home gym. Inside the apartments: wide-plank wood floors, kitchens with oak and lacquer cabinets, marble counters and paneled Fisher and Paykel appliances, marble and limestone baths, central heating and cooling, and an in-unit washer and dryer. There's also a common roof deck with an outdoor kitchen and a package room.

Prospect Heights Highlights

Prospect Heights is the most central piece of brownstone Brooklyn, with Prospect Park, the Brooklyn Museum and the Central Library within a few blocks and the restaurants of Vanderbilt and Washington Avenues close by. 515 Dean sits on the neighborhood's western edge near Boerum Hill and Fort Greene, so the Atlantic Avenue hub is an easy walk.

The 2 and 3 at Bergen Street, about a 2-minute walk
The B and Q at 7th Avenue and the Atlantic Avenue and Barclays Center hub, each about 6 to 7 minutes
The C at Lafayette Avenue, about 8 minutes
Vanderbilt Avenue's restaurants nearby, with Prospect Park just up the hill

Katie's Take

I track every new development in Brooklyn, and here's how this one compares: at about $1,790 a square foot, 515 Dean is the highest-priced new condo I track in Prospect Heights, above The Prospect (about $1,668) and 311 Eastern Parkway (about $1,414), and it's also the fastest, with three contracts in under two months and an average of 11 days to contract. Family-size three-bedrooms with outdoor space and an elevator are scarce here, and buyers are paying for that. If you want one of the garden homes, get on the list now, because I'd expect them to go quickly once they list.
