A Mixed-Use Conversion Brings Four Condos to 159 Baltic Street in Cobble Hill

Nov 1

Welcome to 159 Baltic Street, a four-unit condo conversion in the heart of Cobble Hill, where new condos almost never come to market. This 1888 building is being reimagined as new homes above a ground-floor commercial space, and it's the only mixed-use project among Cobble Hill's recent condo filings. The sponsor is Ascenterra Development.

Where Things Stand

The offering plan for 159 Baltic Street was submitted to the New York State Attorney General on February 4, 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), so at about nine months this plan is near the end of that window and acceptance could come any time now. Join my early access list below and you'll hear about pricing and launch timing before it reaches StreetEasy.

What We Know So Far

Four condos above a ground-floor commercial space in an 1888 building
About 8,650 square feet in total, including roughly 2,500 square feet of commercial space, which leaves about 6,000 square feet for the homes
Likely large floor-through or duplex homes, based on that size (the final mix isn't public yet)
Offering plan filed: February 4, 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

Four homes above a small commercial space is a classic Cobble Hill setup, intimate and woven into the streetscape of a historic district block. The conversion takes the building from a rental with more apartments down to a handful of larger homes. Based on the filings it looks like a walk-up. Final pricing, common charges and the unit mix will be public once the plan is accepted.

Cobble Hill Highlights

Cobble Hill is one of the most quietly charming neighborhoods in Brooklyn, with Cobble Hill Park as its living room and beautifully kept brownstone blocks protected by the historic district. Smith Street, Court Street and Atlantic Avenue are all a short walk away, along with Brooklyn Heights and Downtown Brooklyn.

The F and G at Bergen Street, about an 8-minute walk
The R at Court Street and the 2, 3, 4 and 5 at Borough Hall, all within about 11 minutes

Katie's Take

I track every new development filing in Brooklyn, and here's how this one compares: Cobble Hill's recent new condos have been either two-home brownstone conversions or the much larger 110 Boerum Place, and 159 Baltic is the only mixed-use building in the group, with four homes above a shop. 181 Baltic Street sold out at about $2,090 per square foot and 110 Boerum Place is averaging about $2,690, so expect this one to price in Cobble Hill's upper tier. 144 Baltic Street, filed a month later, was accepted on October 23, 2026, so this plan could be close behind, and if you want Cobble Hill new construction with more than one neighbor, it's the next one to come up.
