In New York City, When Form Follows Finance the Sky's The Limit

The hyperreal renderings predicting New York City’s skyline in 2018 are coming to life as the city’s wealth physically manifests into the next generation of skyscrapers. Just like millennials and their ability to kill whole industries singlehandedly, we are still fixated on the supertalls: how tall, how expensive, how record-breaking? Obsession with this typology centers around their excessive, bourgeois nature, but – at least among architects – rarely has much regard for the processes which enable the phenomenon.
SHoP Architects' Super Tall Tower Approved, Sets Precedent for NYC

UPDATE: SHoP Architects' ultra-thin, 100-unit apartment tower has now won approval from the New York City Landmarks Commission. Once complete in 2016, the 1,350-foot structure will offer luxury apartments that peer down at the Empire State Building and rise just above the One World Trade Center’s roofline.
When Vishaan Chakrabarti, principal at ShoP Architects, spoke recently of building high-density cities, he meant it.
Renderings from the architecture firm show Manhattan's skyline will soon welcome its newest "super tall" building, a strikingly skinny residential tower rising 411 meters (1,350 feet) on a puny 13 meter (43 feet) wide site just two blocks south of Central Park.
