High Line Nine is a new collection of art galleries located along a central throughway directly under the High Line in West Chelsea, which was once an industrial area of Manhattan that is now home to many art galleries and cultural institutions. Designed by studioMDA and developed by Related Companies - High Line Nine is a new turn-key gallery concept that reinterprets the European arcade of the 19th century and applies its programmatic elements to art galleries. 

The facade, cast in white bronze, embraces the history of the site, which was home to a metal recycling yard for more than 50 years. studioMDA collaborated with Polich Tallix, a foundry that has a long history of working with artists, to create the intricate facade. studioMDA scanned a slate plate to extract its texture and then digitally manipulated this texture to create a monolithic pattern that runs the whole width of the facade. This digital model then formed the basis of 3d-printed sand molds that were later cast in white bronze and divided into panels for installation on site. The result is a testament to the collaborative work between architect and fabricator, while speaking to the history of the site and creating a powerful visual marker for the entrances to the High Line Nine.
