I wish we had built a small house.  Today, when I received my online update from 
Houzz, I was tortured again after being shown a
 fabulous 540 square foot house for a family of 4.  They did a great job making every inch pay off.  It may be small on space, but it's loaded with charm.
Interestingly, the roof is a "living roof" and provides valuable insulation.
