The construction of a skyscraper in New York City entails, among many other concerns, protecting pedestrians walking past the building zone. Oftentimes, the temporary scaffolding is an eyesore, intended for safety and nothing more. This was thought to be the case when ground broke for Zaha Hadid’s newest tower, 520 West 28th, located next to the city’s popular High Line park. Yet, the infrastructure sheltering its passersby is distinctly different; it was created by the architect herself.

Part protection, part art installation, the cocoonlike structure—named Allongé (“to lengthen” in French)—is composed of a silver metallic fabric stretched over a curvilinear metal frame, mimicking the tower slowly rising above.

Visitors walking through the 14.5-foot-high, 112-foot-long installation will recognize Hadid’s signature aesthetic, one in which form not only follows function but is also drawn along by the narrative of movement through space. Allongé, which went up earlier this month, will only remain in place for a limited time.
