Kohn Pedersen Fox (KPF) is racking up an impressive collection of superlatives with a host of new glass towers in New York City. Of course there is Hudson Yards where a glossy KPF-designed building will become the tallest tower at the country's largest private development site, but that is just the start of it. In April, renderings appeared for the firm’s 64-story, cantilevering glass tower in Gramercy. The structure, which has a multi-story masonry facade, reaches 777 feet, making it the tallest residential building between Midtown and Downtown. Unsurprisingly, 45 East 22nd Street is going condo. Moving right along to 101 Tribeca, another all-glass condo building. NY YIMBY reported that this tower, which houses 129 units, rises from a more narrow base and then curves its way up to a pinnacle at 950 feet. At that height, 101 becomes the tallest residential building in Lower Manhattan...for now. Now back to Hudson Yards for a moment. As KPF's 30 Hudson Yards rises to 1,227 feet and its more modest sibling, 10 Hudson Yards, climbs to a respectable 895, new renderings surfaced for 55 Hudson Yards. This tower, designed by KPF and Kevin Roche, is still glassy, but slightly less so thanks to a metallic grid that frames its 900 feet. According to the developer, Related, the 1.3-million-square-foot structure is inspired by early modernism and Soho commercial buildings. And then there is One Vanderbilt in Midtown. According to NY YIMBY, this glass giant reaches a pinnacle at 1,450 feet making it the second tallest tower in New York. But why stop there? If One Vandy gets approved to go just one foot higher it gains yet another superlative—topping Chicago's Willis Tower. And that, folks, makes it the second tallest tower in the Western Hemisphere. While not officially approved, the building has already become the glossy symbol of Midtown East Rezoning—a plan to upzone the area around Grand Central Terminal. That proposal died under Mayor Bloomberg, but has found new life under his successor. If the controversial rezoning ultimately does move forward, it likely won't take effect until 2016. Fear not One Vanderbilt, the city is expected to give this 1.6-million-square-foot tower a special permit to kick things off ahead of schedule.
