Honestly having been introduced to the McMansion I don't know how the construction market doesn't collapse from lack of interest. It's like the real estate version of when homer simpson got to design a car.

On the opposite end in Britain we have the "Luxury Apartment", which is where local developers create a perfect replica of a soviet two-room flat but charge you 50% of your income to live there rather than Khrushchev's customary 3%. You can sit on the two seat couch in front of the TV, reach behind you without standing up, and load the washing machine.
