If we're going to cite problems, mine would be that the concept probably only works with one person. With any more, everybody has to coordinate what "rooms" are available and the dependency graphs could be quite odd. Can I cook breakfast if you're sleeping in? Can I get to the shower if you're watching a movie? I would expect that even two people would be significantly inconvenienced and three might just lock up due to contention. Smaller, dedicated rooms may suck, but at least they are reasonably independent.
But hey, for one guy, awesome. It's certainly in the running for "ultimate bachelor pad".
My apartment is smaller and my friends who live in Nagoya refer to it as Castle Patrick. (Half a decade of living in ~120 sq feet will alter your perceptions a bit.)
(P.S. And they wonder why I won't move to Nagoya.)
