The bubbling and bulging sculptural windows of 515 West 18th Street in Chelsea are making their way toward the tops of the new pair of residential buildings. The reinforced concrete structures, which straddle the High Line, are designed by Thomas Heatherwick of Heatherwick Studio and developed by Related Companies. The entire site takes up the eastern half of the parcel of land along Tenth Avenue between West 18th Street and West 19th Street. The taller, 22-story sibling on the western end of the property recently topped out across from the shorter, ten-story component. Both will eventually be enclosed with the same architectural curtain wall of gray-colored bricks and bulbous bay windows. SLCE Architects is the executive architect of the project.

Photos from YIMBY user baronson shows the rising façade and the wide corner windows that are just beginning to be put in place. A protective film is still on the glass but will be removed at a later time.

Installation of the ornamental windows on the ten-story development could be finished by the end of the summer, but it will likely take more time for the envelope of the other building to be completed. The brick façade that intersperses the windows is making its way up both structures.

The development at 515 West 18th Street is one of two properties that is intersected by the High Line, along with 505 West 19th Street, which is located to the north and across the street from Thomas Heatherwick’s construction site. Bjarke Ingel’s mixed-use condo and hotel at 76 Eleventh Avenue, aka The XI, also has the High Line run through part of the project, albeit only along the edge of both twisting structures.

Work on 515 West 18th Street is expected to be completed in 2020.
