A Park Slope Rowhouse Becomes Two Condos at 414 Bergen Street

Nov 2

414 Bergen Street is a two-unit condo taking shape inside an 1878 Italianate rowhouse in the North Slope, on Bergen Street near 5th Avenue. It's steps from the 2 and 3 at Bergen Street and about a 5-minute walk to Barclays Center and Atlantic Terminal, and it's the smallest condo filing I'm tracking in Park Slope.

Where Things Stand

The offering plan for 414 Bergen Street was submitted to the New York State Attorney General on August 31, 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 February and May 2027. I'd expect the project to look fairly similar to 389 Bergen Street, which was converted on the block not long ago.

What We Know So Far

Two condos in a renovated 1878 rowhouse
The original two-story house is being enlarged up and back to three stories plus a basement, about 5,800 square feet in total
Likely two large duplexes, one with the garden and one on top (the final layouts aren't public yet)
Offering plan filed: August 31, 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

Two homes in a renovated historic rowhouse is about as boutique as a condo gets. Buyers get the character of a 19th-century Park Slope house with updated systems and layouts, and the chance to be the first owner of the new home. If the split follows the usual pattern, the lower duplex would have the rear garden and the upper duplex the top floor, but the details won't be public until the plan is accepted.

Park Slope Highlights

414 Bergen Street sits in the North Slope, where Park Slope meets Prospect Heights and Boerum Hill, with some of the best transit access in Brooklyn. 5th Avenue's restaurants are around the corner, and Flatbush Avenue and Atlantic Terminal are a few minutes away.

The 2 and 3 at Bergen Street, about a 4-minute walk
Atlantic Avenue-Barclays Center (B, D, N, Q, R, 2, 3, 4, 5 and the LIRR), about 5 minutes
The R at Union Street, about 9 minutes
Barclays Center, Dean Playground and BAM, all within about 6 minutes

Katie's Take

I track every new development filing in Brooklyn, and this one stands out because it's the smallest condo filing in Park Slope right now: two homes in an 1878 house at the north end of the neighborhood, steps from Atlantic Terminal. The closest comparisons are the brownstone and gut-rehab conversions selling now, like 132 Sixth Avenue at about $1,940 a square foot and 511 8th Avenue at about $1,740, and that's the range I'd watch when pricing comes out. With only two homes, there won't be much choice, so it helps to know early which duplex would fit you.
