Dive Brief:

• Towers are rising in midtown Manhattan, and several of them are tours de force of architects' ability to push buildings up on minimal footprints.
• The tallest so far, 111 W. 57th St. on what is becoming known as Billionaires Row because of the price of the floor-through units, will 1,350 feet tall with an aspect ratio of only 1:23.
• Architect Vishaan Chakrabarti, a partner in the SHoP design firm that drew 111 W. 57th, said the building had several challenges, and it will have pass-throughs for wind and a tuned mass damper.

Dive Insight:

A tall, skinny structure has a payback for the developers because of the views it allows from the residential units and the prices those bring. In the 111 W. 57th building, they will run from $5 million to over $100 million apiece. New York has seven 1,000-foot-plus towers, and there are more than that either underway now or scheduled to break ground this year.
