I've noticed something odd about my gut-reaction admiration for these sorts of homes.
Let's face it, they just look so charming, and they get so much attention for being so small and tidy. Yet when you stop and think about the appeal of the home, really the thing that makes it work is the gobs of surrounding open space.
If you take dozens of these exact same little houses and build them in tightly spaced rows and columns (and perhaps even vertical stacks), suddenly it becomes supremely dystopian. A single little house is "charming". Masses of them crammed together is a prison camp.
