Below-grade work is underway at 275 Flatbush Avenue Extension, the site of a five-tower residential complex in Downtown Brooklyn. Designed by J Frankl Architects and developed by The Jay Group, the conjoined structures will stand 27 stories and 293 feet tall, and will yield a combined 450 units. The property is alternately addressed as 165 Willoughby Street and located at the corner of Flatbush Avenue Extension and Willoughby Street.

Demolition at the site was completed in late 2024 and excavation and piling work is currently in progress. The below rendering posted to the construction board is oriented looking northwest from the intersection of Willoughby Street and Fleet Place, depicting the new structure surrounding the 12-story residential holdout at 167 Willoughby Street. The exterior features an idiosyncratic design incorporating dark floor-to-ceiling glass and an irregular pattern of white mullions.

The 39,000-square-foot assemblage was formed from six adjacent parcels including 104-106 Fleet Place, 159 and 166 Willoughby Street, and 287 Flatbush Avenue Extension.

The nearest subways from the development are the B, Q, and R trains at the DeKalb Avenue station.

  1. The five separate towers is an interesting strategy – Curious why that would be better than just two?

  2. With those views, who wouldn’t want to live on the 21TH, 22TH or 23TH Floors? Hmmmm.

  3. It’s too bad they have to build around that silly holdout on the corner.

    “idiosyncratic design” is one way of describing it.
    Yay for the holdout. It’s not even 5 years old yet. And it seems to be the better looking of the two.

  5. Mediocre filler. It’s such a prominent corner, I was really hoping for at least another Toren-style tower, not this forgettable mid-rise gunk. Hopefully at some point the low rise on the triangular spot across the street that is occupied by the health department will get redeveloped. What a waste of space.

  6. Why five buildings? To avoid the wage requirements, part of the 485-x tax break, applying to buildings over 99 units.

    5 towers? The Poor tower (nee Poor Door); the BLS student dorm types; the working stiff DINKS; Pied a terre’s; and livin’ large Master of the Universe penthouses. Code-named Chevy, Pontiac, Buick, Oldsmobile and Cadillac.
