Tolib Mansurov plans 20-unit condo project at 254 Flatbush Avenue in Park Slope

• Eight-story mixed use building planned with 20 residential units
• Includes over 8,200 square feet of commercial space
• Located near Bergen Street subway station in Park Slope

What this project means for Park Slope development

Plans have been filed for a new mixed-use building at 254 Flatbush Avenue, adding new density to a prime Park Slope corridor. The project is being led by Tolib Mansurov through 250 Flatbush LLC. The site will replace a low-rise structure, continuing the trend of redeveloping underused properties along Flatbush Avenue. Park Slope remains one of Brooklyn’s most stable and desirable neighborhoods, making new development opportunities limited but valuable.

What the unit size means for condo positioning

The building will include 20 residences with an average unit size of about 1,358 square feet. This suggests a condo product targeting larger households and buyers seeking more space. Larger units are less common in new Brooklyn developments, which can support higher pricing.

This positioning aligns with Park Slope’s family-oriented demand.

What the mixed-use component means for income

The project includes over 8,000 square feet of commercial space on the lower floors. Retail along Flatbush Avenue benefits from strong foot traffic and visibility. This adds a steady income stream and enhances the overall value of the asset. Mixed-use properties in this area tend to perform well due to limited supply.

What location and transit mean for demand

The property is located one block from the Bergen Street station, served by the 2 and 3 trains. Access to transit is a major driver of both buyer and tenant demand in Brooklyn. This location offers strong connectivity to Manhattan and other parts of the city. For investors and end users, transit proximity adds long-term value.

What permits and demolition mean for timeline

Demolition permits have already been filed for the existing structure on the site. This indicates the project is moving forward, though no construction timeline has been announced. As with many developments, timing will depend on approvals and market conditions. Early permitting activity suggests progress toward eventual construction.

What this means for Brooklyn investors

This project highlights the continued demand for larger condo units in prime Brooklyn neighborhoods. With limited new supply in Park Slope, developments like this are positioned to attract strong interest. The combination of location, unit size, and mixed-use income supports long-term value. For investors, this is a high-barrier market where well-positioned projects can perform consistently.
