241 13th Street is a new four-unit condo building going up from the ground on 13th Street between 4th and 5th Avenues in the South Slope, a few minutes from the F, G and R. The developer is Kilrock Capital, and the new building replaces a two-family house that sold in 2022.
Where Things Stand
The offering plan for 241 13th Street was submitted to the New York State Attorney General on May 21, 2025, and it is still awaiting acceptance. Earlier this year an outside data feed showed one of the four homes as sold, but that didn't reflect a sponsor sale. As of November 1, 2026, none of the homes have been listed or sold, 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 more than 17 months, this review is running well past that, though a long review isn't unusual for new construction here: 270 14th Street, a block away, took about 14 months.

What We Know So Far
Four residences across four floors
About 6,226 square feet of total floor area on the building permit, so homes likely average about 1,500 square feet
Likely three-bedroom homes; the final mix comes with the plan
A backyard for the ground-floor home
Offering plan submitted May 21, 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
Four homes is a true boutique scale. It's a walk-up with an intercom, and the backyard makes the ground-floor home a good fit for a buyer who wants private outdoor space. New construction means new systems and new layouts throughout; finishes will be detailed in the accepted plan.
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. 241 13th Street sits in the South Slope, close to 5th Avenue and one of the best transit spots in the neighborhood.
The F, G and R at 4th Avenue-9th Street, about a 4-minute walk
The R at Prospect Avenue, about 4 minutes
The 5th Avenue shops and restaurants, right around the corner, with Prospect Park within easy reach
Katie's Take
I track every new development filing in Brooklyn, and 241 13th Street is one of only three ground-up buildings in Park Slope's pipeline, with likely three-bedroom homes of about 1,500 square feet. The closest comparison, 270 14th Street a block south, has sold three of its four homes at about $1,449 a square foot, so I'd use that as a starting reference rather than the $1,900-plus figures at conversions closer to the park. If you want a new three-bedroom near the F, G and R, get on the list now, since this filing is well overdue for acceptance.
