Top 20 Tallest Completed Buildings in the World

14. 432 Park Avenue

Locale: New York City, United States

Height: 1,397 feet

Completion Year: 2015

This is a new entrance in the list with 88 floors. Other than emerging as the tallest buildings it is being noted worldwide due to its pencil-thin design. The architects have given this narrowness deliberately to combat dense space issues. Super-slim, super-tall, super-smart design is what describes this the best.
