A Restored 1877 Building Becomes Three Boutique Condos at 183 Prospect Place

Nov 1

Welcome to 183 Prospect Place, three condos taking shape inside an 1877 house on a classic Prospect Heights block, steps from Grand Army Plaza and the top corner of Prospect Park. It's the only three-home building among the neighborhood's current condo filings. The sponsor entity is Prospect Itanu LLC.

Where Things Stand

The offering plan for 183 Prospect Place was submitted to the New York State Attorney General on June 9, 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 November 2026 and March 2027.

What We Know So Far

Three condos in an 1877 two-family house being renovated, enlarged and converted to three homes
About 5,020 square feet of total floor area in the DOB filing, or roughly 1,670 square feet per home
Likely a mix of full-floor and duplex homes, based on that size (the final mix isn't public yet)
Offering plan filed: June 9, 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

With just three residences, 183 Prospect Place is about as intimate as a condo building gets. Converting an 1877 house means the historic character stays while the systems, layouts and finishes are brought fully up to date, so you get the original architecture with the comfort of new construction. 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.

Prospect Heights Highlights

Prospect Heights is the most central piece of brownstone Brooklyn, bordering Park Slope, Crown Heights, Fort Greene and Clinton Hill all at once. Prospect Park, the Brooklyn Museum, the Brooklyn Botanic Garden and the Central Library are all within a few blocks, and Vanderbilt and Washington Avenues carry the neighborhood's restaurants and cafes. I'm lucky to call this area home, so I'm admittedly quite biased, and 183 Prospect Place sits right in the middle of it.

The B and Q at 7th Avenue, about a 3-minute walk
The 2 and 3 at Grand Army Plaza, about 4 minutes
The C at Clinton-Washington Avenues, about 9 minutes
The full Atlantic Avenue-Barclays Center hub, with the B, D, N, Q, R, 2, 3, 4, 5 and the LIRR, about 12 minutes

Katie's Take

I track every new development filing in Brooklyn, and this one stands out because it's the only three-home building in Prospect Heights' current filings, sitting in size between the two-home conversions on Park Place and Saint Marks Avenue and the four-home new build at 766 Dean Street. At roughly 1,670 square feet per home, it points to the kind of family-size layouts buyers in this neighborhood ask me about most, inside one of its oldest houses. Acceptance most likely comes between November 2026 and March 2027, and with only three homes, there won't be many chances at one.
