Stellar plans two-tower, 319-unit project in Park Slope

Stellar Management submitted a plan to build a 319-unit development with two towers at 341 10th Street in Park Slope, Brooklyn, on a parcel the development firm has long owned and currently occupied by two buildings with 154 units which will remain. Stellar Management submitted the plan with the city’s Department of City Planning, as part of the uniform land use review procedure, or ULURP, to get a rezoning of the parcel and the creation of a Large Scale General Development permit. Marvel Designs is the architect and Stellar’s Benjamin Rubenstein submitted the plan on May 4, 2023 through number 2020K0477.

The publication Patch reported last May on a early concept of this project, which had been discussed in a landlord-tenant meeting in December 2021. The article described the development as having one 18-story building with about 200 units and another building of approximately the same size.

On this tax lot, in October 2021, Stellar Management submitted a new building construction project for a three-unit, 1,513 square-foot residential (R-2) building at 309 10 Street in Park Slope, Brooklyn. The plan was filed with the New York City Department of Buildings under job number B00601179.

According to the new zoning application, “The Proposed Actions would facilitate the development of the two new buildings: the “9th Street Building” would include a 17‐story tower (up to 201 feet tall to the top of the bulkhead) and the “10th Street Building” would be 19 stories (18 floors plus a penthouse; up to 225 feet tall to the top of the bulkhead).

“Both buildings would contain residential space on the upper floors: with a combined total of approximately 271,380 [gross square feet] of residential space, the new buildings would contain up to 319 [dwelling units] (assuming an average unit size of 850 sf/unit), of which 64 to 96 DUs [dwelling units] would be affordable.

“The two buildings would total approximately 282,774 gsf [gross square feet] (245,296 zsf [zoning square feet]); including the existing multifamily apartment building, with the addition of the new buildings, the Project Site would contain a total of 456,153 gsf (409,476 zsf, 5.93 FAR). Including the 154 DUs in the existing building, with the addition of the new buildings, the Project Site would contain a total of 473 DUs. The new buildings would also include approximately 6,750 gsf of retail space and approximately 4,600 gsf of community facility space (assumed to be medical office). The proposed project would also result in a reduction of parking on the Project Site from 115 spaces to 39 spaces accessory to the residential buildings…”
