Miami's $300 million 'exoskeleton' skyscraper is complete after 7 years. Look inside the Zaha Hadid-designed tower, which comes with a private rooftop helipad.

A Miami skyscraper designed by a legendary architect is complete after seven years and almost $300 million in construction costs, The Wall Street Journal reports.

One Thousand Museum is one of the last designed by famed Iraqi-British architect Zaha Hadid, who was nicknamed "Queen of the Curve" before her death in 2016.

The tower has a distinctive "exoskeleton" exterior that's made up of more than 4,800 pieces of glass-fiber-reinforced concrete that were shipped from Dubai.

The 62-story luxury tower has reached completion amid a surplus of high-end condos on the market in Miami.

Fewer foreign buyers are interested in buying luxury condos in Miami as South American economies — once a major source of real-estate investment in Miami — falter.

Additionally, as Hillary Hoffower wrote for Business Insider, "new-development condos also emerged onto the market as current condo owners began to sell, some encouraged by the strong value of the US dollar — creating the perfect recipe for a surplus."

Although about 64% of the residences were sold before the building was even finished, Miami developers usually try to presell 85-90% of the units in a building, Peter Zalewski of Miami real-estate consulting firm Condo Vultures told The Wall Street Journal.
