The big buzzword today in housing is sustainability followed by Green building. In the USA the 3 bedroom, 2 bath, 2000 square foot house is considered a standard. For some areas of the country it is labeled as a "starter" home for the first time buyer.
This house fits into its site very well and its site footprint is very small. The total floor area is probably about 1500 square feet. Compare this to housing in Japan or New York where homeowners live in much smaller spaces. Living smaller is less expensive, respects the environment by cutting down on urban sprawl and forces you to think before buying more "stuff."
