Two Boutique Homes Coming to 361 Union Street in Carroll Gardens
Welcome to 361 Union Street, a two-home boutique condo conversion steps from Carroll Park in the heart of Carroll Gardens. Set inside an 1899 building being carefully renovated, this is about as small-scale and neighborhood-rooted as new development gets in this part of Brooklyn.
Where Things Stand
The offering plan for 361 Union Street was submitted to the New York State Attorney General on November 4, 2025, and it is currently awaiting acceptance. No units are for sale yet; there is no public pricing, and the building is not yet on StreetEasy. Plans of this kind typically take several months to be reviewed and accepted.
The Numbers So Far
This is a two-unit building across four floors, which points to generously sized homes, quite possibly a pair of duplexes. This same sponsor built 301 Degraw Street nearby, a building where I had a client purchase and they’ve been very pleased wtih the property.

A Boutique Condo Experience
A two-unit building is boutique in the truest sense. Each home gets the full attention of the renovation, and buyers get the rare combination of a brand-new interior inside a historic Carroll Gardens building. This building will have the vibe and lifestyle of a townhouse with the convenience of a modern condominium.
The Heart of Carroll Gardens
Carroll Gardens is one of Brooklyn’s most quietly held brownstone neighborhoods. Tree-lined blocks, an Italian-American history that still shows up in the bakeries and shops along Court Street, the restaurant row on Smith Street, and Carroll Park at the center make this one of the most consistently charming corners of the borough. The building stock is small-scale, so new condo development at any meaningful number of units is genuinely rare.
The F and G trains at Carroll Street are about a 2-minute walk away, making it one of the best transit locations in the neighborhood.
The D, N, and R at Union Street are roughly a 12-minute walk for a quick ride into Manhattan.
The zoned elementary school is P.S. 032 Samuels Mills Sprole in District 15.
Designed for Modern Brooklyn Living
Buyers who love Carroll Gardens often face a hard choice between a full townhouse and an older co-op. A newly renovated two-unit condo like 361 Union Street threads that needle: brownstone-block character, a private garden, and a brand-new interior, without taking on an entire house.
