Well if you looked at the schematics for the sections it is conceivable that it is habitable. There is a company in the US doing homes somewhat like this [1] where the market is for building a house in a place with a limited building cycle (think mountain cabins). I've walked through the BluHome factory and met with their engineers, they pre-fab everything, when they 'build' it on site its basically an unfolding operation.
That said, the Broad building looks to have the necessary systems (perhaps not fire suppression) and it looks in the video like they build the crane into the building (which is sort of a waste of a crane) but it is "space." Now if he wanted to impress folks he could build two of those in Haiti for the folks who are still living in tents because their shacks did not survive an earthquake.
