A Fresh Vision for 21 Lefferts Place

21 Lefferts Place is a boutique condominium currently under development in Clinton Hill, Brooklyn. I love the Lefferts Place block because it's tucked away from the chaos of Fulton and Atlantic, yet still convenient to the subway. The leafy trees and brownstones don’t hurt either.

The offering plan was accepted on Ocober 7th, 2025 which means that the apartment layouts and estimated price points are now available.

Previously a vacant lot, the site now has permits filed for a four-story residential building with six residences. The proposed building is approximately 40 feet tall, with a total area of 5,992 sq ft, of which ~4,478 sq ft is residential.

DJLU Architects is listed as the architect of record, and the project includes a cellar and a rear yard space.

Unit Count & Layouts

There are six units in the building- 2 larger apartments on the upper and lower floors with outdoor space. The 2nd and 3rd floors will each have a 1-bedroom. There are three three-bedroom units on the 4th floor, each with a roof space, listed for around $1,700,000. The one bedrooms will start at approximately $795,000.

Estimated common charges will be around $300 for the one bedrooms and $700 for the larger units.

Estimated monthly taxes will be $800 for the one bedrooms and $1,300 for the larger units.

Design & Features

The structure is expected to use steel framing, include a cellar, and have a moderately sized rear yard.
Given the boutique scale, emphasis will likely be on quality finishes, high-performance building envelope, and light-filled layouts.
Outdoor spaces (balconies, terraces, or rear yard access) could become a premium differentiator in this project.

Neighborhood & Location Appeal

Clinton Hill is one of Brooklyn’s most desirable addresses for design-conscious buyers, thanks to its mixture of historic homes, greenery, and cultural amenities. The building facade aligns nicely with the brownstone and historic districts nearby.

Transit & Connectivity

The site sits between St. James Place and Grand Avenue, about 3 blocks west of the Franklin Avenue station (A & C lines). The shuttle at Franklin Avenue also provides easy access to Prospect Park.
Nearby subway options also include the G train (Clinton–Washington Avenues), and multiple local bus lines. C

Historic & Urban Context

Lefferts Place is part of the Clinton Hill South Historic District, which includes many Neo-Grec and Late Victorian row houses built between the 1850s and early 20th century.
The design approach here must strike a balance — a modern building that respects the scale, rhythm, and character of its surroundings.

Because of its setting, 21 Lefferts Place offers a rare combination: newly built residences in a contextually rich, architecturally sensitive envelope.

Development Timeline & Sales Status

The permit filing occurred in 2019. The building has been in the works for a while, but it appears to be approaching the final stretch.
With an approved offering plan, we can expect public listings as soon as the building has a unit available to show. Nothing is listed publicly, but I do have access to the selling agent if you’d like to get an early tour.
