Construction is topping out on 579 Sackett Street, an 11-story residential building in Gowanus, Brooklyn. Designed by Kao Hwa Lee Architects and developed by Hershy Silberstein of BlueSky Developers, the 110-foot-tall structure will span 46,943 square feet and yield 64 rental units with an average scope of 681 square feet. The project will also include 3,348 square feet of ground-floor retail space. The property is alternately addressed as 224 3rd Avenue and located at the corner of 3rd Avenue and Sackett Street.
The entire reinforced concrete superstructure was built since our last update in May 2025, when excavation and piling work was just getting underway. Crews are now forming the final floors of the building, which stands fully shrouded in a dense assembly of scaffolding and construction netting. Most of the exterior is enclosed in insulation boards, and some of the windows have been installed within the fenestration voids. A crane is being used to lift equipment to the top of the building.

The main rendering from the info board shows a multifaceted massing with interlocking volumes clad in contrasting white and dark brown brick on the southern and eastern elevations. The fenestration will be composed of punched floor-to-ceiling windows with black frames and mullions, and several stacks of balconies with glass railings will hang from the broader eastern face along 3rd Avenue. The ground-floor retail frontage will be lined with expansive double-height windows.
Below is the previous design for 579 Sackett Street. Several architectural elements were carried over into the current iteration.

Developer Hershy Silberstein purchased 579 Sackett Street from Martin Nussbaum for $16.5 million inn early 2025 and filed demolition permits in April 2025 for its one-story occupant, seen in the below Google Street View image from before its razing.

Residential amenities will include a 32-bike storage space in the cellar level, a fitness center, and outdoor recreation areas on the first floor and rooftop. The closest subway from the development is the R train at the Union Street station along 4th Avenue.
579 Sackett Street has an anticipated completion date of April 2026, as posted on site. However, YIMBY expects work to finish around the end of the year.

Kind of a mess.
And AKS1TFK sure is a strange name for a building.
Nice netting.
