The race to build the tallest residential building in the world has long been underway along Billionaires’ Row, but 111 West 57th Street not only boasts height (at 1,428 feet it’ll surpass the current record holder, 1,396-foot 432 Park Avenue until the 1,500-foot Central Park Tower tops out) but a frame that is so slender (a ratio of 1:24) it garners it the title of skinniest skyscraper in the world. And after six years watching the development unfold, listings have finally gone live for the 46-unit condo, first spotted by Curbed. The first batch includes seven units, six of which are three-bedrooms ranging from $18 to $30 million, along with a $56 million penthouse.

Here’s a new set of images of Property Markets Group‘s and JDS Development’s 111 West 57th Street. In case you haven’t been paying attention, the highly-anticipated tower will be among the tallest residential skyscrapers in the world, climbing some 1,421 feet high to its tip. Designed by SHoP Architects, the feathery spire is sheathed in terra cotta, bronze and a glass curtain wall. The tower will be the most slender skyscraper in the world with a height to width ratio of 24:1.
