Over the last two decades, a new type of building has invaded New York City: The super skinny supertall known as a “super-slender.” This new generation of skyscrapers range from 50 to 100 stories, are almost uniformly filled with luxury housing—and some are wedged into the city with astoundingly tiny 45-feet-wide footprints.
A new exhibition at the Skyscraper Museum in New York looks at how the slender movement came to be: from the air rights laws that made them possible, to the design innovations that allow architects to build such spindle-thin towers.
18 new “super-slenders” under construction in New York
“Slenderness” is an actual term by engineers that historically describes a structure with a 1:10 or 1:12 ratio when comparing a building’s width to its height. In the last few years, newer buildings have been able to achieve even more jaw-dropping ratios. The Nordstrom Tower going up on 57th Street has a ratio of 1:23! This will make it the most slender building in the world.
