The first sculptural glass panels on Thomas Heatherwick’s premiere residential project at 515 West 18th Street are starting to be installed. The glass and metal frames are rising on the western elevation of the shorter ten-story building, which has topped out along Tenth Avenue. Heatherwick’s pair of architecturally matching structures straddle the High Line and will be an interesting addition to the Chelsea neighborhood. The taller half of the complex is rising on the western edge of the elevated park and will soon stand 22 stories high. The site is being developed by Related Companies.

The best angle to see the bubbling grid of windows is from the corners, where the degree to which they protrude from the gray-colored brick façade is more apparent. This design will also make the building appear much bolder and more voluminous in terms of its aesthetics and proportions with the structural columns and floor slabs.

The 22-story counterpart should top off sometime by the end of spring or early summer. Construction only began to rise above street level back in early December and quickly shot up in four months. There will be a total of 181 units at 515 West 18th Street, with amenities including a fitness center and spa, an entertainment room, residential lounges, and parking for 175 vehicles. There will also be landscaped outdoor rooftop terraces on both towers that overlook Chelsea, the Hudson River, and the second phase of the High Line.

Completion of 515 West 18th Street should happen sometime next year.
