750 Seventh Avenue is a 615 ft (187m) tall skyscraper in New York City. It was completed in 1989 and has 36 floors. Kevin Roche John Dinkeloo & Associate designed the building, and it is owned by Hines, a Texas based real estate investment company. The building's continuous helix design, culminating in a chimney-like extension, was caused by the New York City Building Code, which requires setbacks. The 84 exterior column transfers exist because of the owner's requirement for a column-free space.
