Curtain wall installation has begun on 9 DeKalb Avenue, soon to be the outer boroughs’ tallest building at 1,066 feet tall and number six on YIMBY’s construction countdown. Designed by SHoP Architects and developed by JDS, the 73-story Downtown Brooklyn residential skyscraper will become the first New York City supertall outside of Manhattan and will yield 425 rental apartments and 150 condominiums.
Recent photos show the state of progress at the site, which is located at the corner of Flatbush Avenue Extension and Fleet Street. Since our last update in early November, the first curtain wall panels have been installed on the lower floors of the steadily rising reinforced concrete superstructure.
Closeup shots reveal the details in the curtain wall, which is composed of floor-to-ceiling glass, stainless steel, and aluminum. The tower’s distinctive hexagonal outline is also becoming more apparent as more floors are created. The massing features some subtle setbacks at various levels across all six sides, ultimately culminating in a tall crown with vertically extruded beams that accentuate the building’s slender figure and verticality. The façade’s combination of glass and metallic paneling helps reflect sunlight, further enhancing its impact.
At the uppermost floors, construction crews can be seen working between the translucent safety cocoon netting and tall sections of newly tied and inserted steel rebar along the edges of the floor plates. Judging by its position in relation to the surrounding structures, its looks like progress has reached one set of mechanical floors, which typically take longer to construct due to their greater number of walls and their use as an outrigger to bring together the concrete core and perimeter columns. There will likely be another mechanical section around two thirds of the way up, below the final set of residential stories.
