Sold Out: Two Condos at 181 Baltic Street in Cobble Hill

Sold Out

Nov 1

181 Baltic Street is a two-condo conversion of a 25-foot-wide brownstone dating to 1839, on Baltic Street between Henry and Clinton Streets in the Cobble Hill Historic District. Both homes are in contract, less than three months after sales launched.

Where Things Stand

Both homes at 181 Baltic Street are in contract as of November 1, 2026, and neither has closed yet. The offering plan was filed on October 27, 2025. The Townhouse Residence listed on June 20, 2026 and went into contract the same day; the Upper Residence listed on July 2 and went into contract on September 11, 2026. That's under three months from first listing to last contract. Across the five other Brooklyn projects of 2 to 6 homes I've tracked to a sellout, the typical one took about three months, so this one sold a little faster than most. The building is by ECKSTRØM, the design and build firm behind 487 Henry Street and 170 Clinton Street. Want to see upcoming projects by this sponsor? Reach out below.

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 an 1839 building is a one-of-a-kind setup. ECKSTRØM restored the brownstone shell and split it into a townhouse-style triplex and an upper duplex, each with substantial private outdoor space. Inside, the palette is natural and restrained: wide-plank European oak floors, custom kitchens imported from Germany, Miele appliances, Calacatta Viola marble counters in the upper home and Waterworks fixtures throughout. It's a walk-up.

Cobble Hill Highlights

Cobble Hill is one of the most quietly charming neighborhoods in Brooklyn, with Cobble Hill Park as its living room, beautifully kept brownstone blocks, and Brooklyn Heights, Downtown Brooklyn and Brooklyn Bridge Park all within walking distance.

The F and G at Bergen Street, about a 7-minute walk
The 2, 3, 4, 5 and R at Borough Hall and Court Street, within about 11 minutes on foot
Cobble Hill Park, Smith Street and Court Street, all close by

Katie's Take

I track every new development in Brooklyn, and here's how this one compares: at about $2,090 a square foot asking, 181 Baltic Street sits below the larger 21-home 110 Boerum Place and a bit above the boutique Carroll Gardens conversions just south. The triplex with its own entrance and garden went into contract the day it listed, while the upper duplex took about ten weeks, which matches what I see across brownstone Brooklyn: the townhouse-style home is the one buyers compete for. If you want one of these in Cobble Hill, 144 Baltic Street and 159 Baltic Street are the next small conversions on the same street to watch.
