5 new skyscrapers broke records as the tallest buildings in their countries this year - take a look

Before the building was finished, the 22,604-square-foot penthouse was declared South Africa's most expensive apartment (worth an estimated $12.4 million in 2015).

The building also has a 128-room hotel and 11 floors of commercial office space. It stands 752 feet tall.

According to one of the building's developers, the Legacy Group, the skyscraper overlooks "the richest square mile in Africa" in Johannesburg's financial district.

A 787-foot vertical tower gives the building its record-breaking height. The leaning tower, meanwhile, is 686 feet tall.

The building's design is deliberate, of course. The structure, which holds 400-plus luxury apartments, has even been designed to withstand a magnitude 7 earthquake.

The Infinity Coast Tower is 770 feet tall.

"We seek to make the most of what the terrain can produce without the intention of competing for titles," Toninho Roncaglio, the commercial director of the building's developer, FG Empreendimentos, told local newspaper Folha de S.Paulo.

The minaret — a tower attached to a mosque — is the tallest in the world, rising 869 feet into the air.

When it comes to earthquake safety, the skyscraper is even sturdier than the Infinity Coast Tower. It's designed to withstand a magnitude 9 quake.
