Brooklyn-based developer Tolib Mansurov is expanding his footprint in Park Slope with plans for an eight-story mixed-use building at 250 Flatbush Avenue. The proposed project, recently filed with the New York City Department of Buildings, would encompass approximately 35,400 square feet, featuring 20 residential units and about 8,300 square feet of commercial space on the ground floor. The design includes a 20-foot backyard, offering outdoor space in the dense urban setting. Mansurov acquired the property in February 2022 for roughly $7.5 million, according to city records. Z Architecture’s Alexander Zhitnik is leading the architectural design for the development.

Mansurov is no stranger to Park Slope’s real estate scene. Earlier this year, he submitted plans for a 99-unit residential building at 67 Fourth Avenue, signaling a continued commitment to residential development in the neighborhood. In September, Mansurov also sold six adjacent sites in Park Slope to Williamsburg-based Borough Developers’ COO Shimon Kleinman for $24 million, demonstrating active portfolio management amid a competitive Brooklyn market.

Despite recent controversy stemming from allegations in 2024 that Mansurov acted as a straw donor in former Mayor Eric Adams’ first mayoral campaign—a case that was ultimately dismissed under the Trump administration—Mansurov has maintained his development activities in the borough. His firm, United Elite Group, has not commented publicly on the allegations or the new project.

Park Slope remains a sought-after area for mixed-use development, balancing residential demand with commercial vitality. Mansurov’s latest filing highlights ongoing investor confidence in Brooklyn’s real estate market, even as the city navigates broader economic uncertainties. The project’s blend of residential units and retail space aligns with neighborhood trends favoring walkable, amenity-rich environments that appeal to families and professionals alike.

With construction timelines yet to be announced, the 250 Flatbush Avenue project represents a significant addition to Park Slope’s evolving skyline and underscores Mansurov’s sustained influence in Brooklyn’s development landscape.
