I'm a bit worried that this can be penny wise and dollar foolish. Increasing density like this temporarily lowers the minimum cost of rent, but the price per square foot skyrockets. I can't imagine that will be good for any of us. I also can't imagine the actual cost of the building being anywhere near that much per person. I pay 50% more (each) with a roommate to live fantastically in a skyscraper that has plenty of room. How much is being pocketed in this arrangement?
