I live in a 2150 square foot apartment with Edith which consists of two baths, one kitchen, four small to tiny bedrooms and one huge living room/loft type space, so I don't resent space at all.
But that home in that article is interior design-wise like a baroque, overdone Dolly Parton nightmare. You would have to chuck at least half the stuff out to actually get those huge spaces to breathe again. The only thing I really like is the pond (or is it a swimming pool?) outside. Other than that it is (over) decorated like a luxury liner, I'd never feel comfortable there.
