no houses

What I first noticed when I got here, the city of Dongtan, is that there were a lot of apartment buildings. Fields of them -- where Ottawa might have a pair of similar towers, or maybe in extreme cases, 3-4, here there were fields of nigh-identical towers, 6, 8, 10+ of them. And they were tall, seriously hi-rise, look up at them from my 14th floor hotel room hi-rise. What took me longer to notice, though, was that there were no houses. By that, I mean no single-family-dwellings. None. There's 4 types of land: commercial (stores, restaurants, etc), industrial (e.g. Samsung), residential (i.e. hi-rise apartment buildings), and park land. No single-family-dwelling residential. No lo-rise residential (as one might see in Rome, or, though less-dense, some sections of Montreal).
