Maybe it's you who suffers from space blindness. :) People can get used to a wide range of personal space availability. A friend who lives north of Dallas, TX lives with his wife in a 1500 sq.ft. house which seems tiny to them and those they know. When I was visiting recently, he was struggling with how to fit all of their stuff in the house, as quite a lot had overflowed into the garage, making it unusable for, you know, parking in.
