> It would be interesting if someone tried this in one of these larger cities with high rises like Singapore. In Singapore, 80% of people today live in what are called HDB flats. These are government subsidized housing projects (with few of the downsides that phrase entails in the west). These HDB buildings (or just "HDBs") are each, eventually, integrated as part of an "estate" which usually comprises one or two grocery stores, some restaurants, maybe a salon or barber shop, hardware store, etc. Given Singapore's population density, there are often several HDBs near each other in one "town." But if you want, you can find one that lets you live in relative isolation, with shopping and eating downstairs, and perhaps a direct connection to the metro to get to work. The playground will be outside, but otherwise you could live almost entirely indoors if you wanted...and some people do, since it's 30 degrees Celsius every day.
