308 14th Street is a ten-unit condo building going up from the ground in the South Slope. What sets it apart is size: the building permit points to homes averaging about 1,400 square feet, a real footprint for a boutique Park Slope building. So many new construction buildings are built with homes under 1,000 square feet, so the size here stands out.
Where Things Stand
The offering plan for 308 14th Street was submitted to the New York State Attorney General on October 31, 2025, and it is awaiting acceptance. No homes are for sale yet, there is no public pricing, and reservations can't be taken.
Across the 55 Brooklyn projects I've tracked from filing to acceptance, the typical wait was about 7 months, and most landed between 5 and 9 months. At a year in, this one is running long, but that isn't unusual on this street: 270 14th Street, up the block, took about 14 months from filing to acceptance.

What We Know So Far
Ten residences across five stories plus a cellar
About 14,076 square feet of total floor area on the building permit, so homes likely average about 1,400 square feet
Likely two- and three-bedroom homes; the final mix comes with the plan
Offering plan submitted October 31, 2025
What's next: the Attorney General's 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 ten homes over five floors, 308 14th Street is a small building. It's new construction, which means modern systems, modern layouts and the chance to be the very first owner of your home. The sponsor entity is Townhouse 308 LLC. Finishes, outdoor space and the final unit mix will be released when the plan is accepted.
Park Slope Highlights
Park Slope is the Brooklyn neighborhood most people picture when they picture Brooklyn: brownstone-lined blocks, Prospect Park at your doorstep, and the shops and restaurants of 5th and 7th Avenues. 308 14th Street sits in the South Slope, below the park side of the neighborhood, where the blocks are a little quieter.
The R at Prospect Avenue, about a 6-minute walk
The F and G at 7th Avenue, about 7 minutes
Prospect Park, the YMCA, Pasta Louise and Nitehawk Cinema, all close by
Katie's Take
I track every new development filing in Brooklyn, and 308 14th Street is one of the larger pending filings in Park Slope at ten homes, behind only 150 Prospect Park West and the newly filed 240 19th Street. Up the block, 270 14th Street has sold three of its four homes at about $1,449 a square foot, one of the lower figures among Park Slope's selling buildings, which is a useful marker for where pricing here could start. If you need three bedrooms in new construction, buildings with this many large homes rarely come up in the Slope, so it pays to be on the list before acceptance.
