Brian Merchant contrasts this project with other skyscrapers:

So, should we cheer or jeer the prospect of mass-produced biggest-ever skyscrapers? And also: why mass-produce ginormous skyscrapers in the first place?

Well, if the specs [that Broad Sustainable Construction] provides are to be believed, mass-manufacturing prefab skyscrapers is much more efficient than our more traditional towers. It’s five times more energy efficient, can be built at half the cost, and packs a lot more people into a smaller space. BSC is going to stuff 30,000 people into these self-contained skyscraper communities—a resident of Sky City will use up 1/100th of the land used by a typical Chinese citizen.

And it really is a city in and of itself—4,450 apartments, nearly 100,000 square feet of indoor vertical farms, 250 hotel rooms, 92 elevators, 30 foot courtyards for athletics, and a six mile ramp that can be used to walk or run around the entire city.
