Avdoo files plans for 2 projects with 125 units in Gowanus

Developer Avdoo filed two plans with the New York City Department of Buildings to develop 125 units on two tax lots fronting the east side of 3rd Avenue between Union and Sackett streets with the addresses 601 Union Street and 610 Sackett Street. The developer owns another adjacent parcel, which is labeled tax lot 12, but that does not yet have development plans filed.

Avdoo published renderings it dubbed 601 Union Street, Yimby reported in August.

Avdoo bought the property for $29.4 million in December 2024. At that time, the site was composed of two tax lots. The current development plan shows three tax lots, with these plans filed for two of the three. The third tax lot with no plans is listed as tax lot 12 in the illustration below.

In the larger project, Shlomi Avdoo of Avdoo submitted a new building construction project for an 86-unit, 127,007 square-foot residential (R-2) building at 601 Union Street, with an alternate address of 241 3rd Avenue, in Gowanus, Brooklyn. The plan was filed on the current tax lot 12 with the New York City Department of Buildings on September 18, 2025 under job number B01278364. But that parcel will be renamed tax lot 13, at a later date, according to the filing. It calls for the construction of an eight-story building. The project is described in the filing as: construct new eight (8) story mixed-use building as per plans filed.

In the second project, Shlomi Avdoo of Avdoo submitted a new building construction project for a 39-unit, 65,988 square-foot residential (R-2) building at 628 Sackett Street in Gowanus, Brooklyn. The plan was filed on tax lot 1 with the New York City Department of Buildings on September 18, 2025 under job number B01278368. It calls for the construction of an eight-story building. The project is described in the filing as: construct new 8-story mixed use building as per plans filed. (This plan was filed incorrectly under tax lot 16, however that lot is owned by another company.)
