Excavation has begun at 444 Carroll Street, the site of a six-story residential building in Gowanus, Brooklyn. Designed by Kao Hwa Lee Architects and developed by David Grunfeld of GW Infinity LLC, the 65-foot-tall structure will span 68,526 square feet and yield 99 rental units with an average scope of 692 square feet. The property is located between 3rd Avenue and the Gowanus Canal, adjacent to the two-tower 420 Carroll Street development.
A team of excavators is busily unearthing the site behind wooden fencing. YIMBY expects foundations will begin formation around the middle of the year.
The rendering in the main photo depicts the southern elevation with a fanning form featuring four protruding volumes with corner balconies. A light beige façade will surround a grid of floor-to-ceiling windows with bronze-hued mullions, and a series of horizontal steel beams will line the edges of each floor plate. An expansive landscaped terrace will sit above the second-story setback, and the building will culminate in a flat roof.
The below diagram outlines 444 Carroll Street’s footprint. The building will have a U-shaped configuration with the broad side abutting 420 Carroll Street, and a courtyard with additional balconies will sit at the center. The project will also create an extension of the Gowanus Canal down 1st Street, directly south of the property.
The property was formerly occupied by a surface-level parking lot.
The nearest subway from the ground-up development is the R train at the Union Street station along 4th Avenue.
444 Carroll Street’s anticipated completion date is slated for April 2027, as noted on site.

Creating a new extension from the canal is really unexpected. There must be some incentive for doing this.
The First Street Turning Basin existed as recently as the early 50’s and was illegally filled in mostly using rubble. As part of the Gowanus Superfund Cleanup, the EPA mandated the excavation and restoration of the basin. It seems like with the new construction going up alongside where the basin was, it’s seen as an opportunity to have a private developer assist with its restoration.
