Recent advancements in structural design, combined with the loosening of density and zoning requirements, has opened the door for the so-called "superslim skyscraper."
From New York to Melbourne to Vancouver, developers are planning high-rise structures on postage-stamp-sized parcels (OK, not that small, but we're talking lots as narrow as 22 feet) in dense urban locations.
Developers love the building type because they can finally take advantage of land that was previously unusable for large multifamily and mixed-use structures.
Some projects, like the Beach & Howe Tower in Vancouver (see No. 2 below), utilize a narrow form to accommodate multiple structures on a given site.
To be considered "superthin" or "slender," a tower must have a height-to-width ratio of at least 10:1. A typical skyscraper, such as the Willis Tower, falls in the 7:1 range. The new crop of skinny towers blows those ratios out of the water. For example, the 111 West 57th Street project in New York City has a height-to-width ratio of 22.5:1.
Here's a quick look at some prominent skinny skyscraper projects in the works:
