Of course, these are generalizations. Also, I did say that the labor per square foot range was wide, 0.5 to 2. The truth of the matter is, as a percentage of the population, very few people live in 600 square foot homes. This is particularly true in the case of families. That's where you really have to start talking about double that space. Anyhow, all-up home construction via traditional means is not cheap. These days transportation costs likely add a non-trivial amount of money to the total. Costs do vary across the country, and so does median income. It would be interesting to find a comparison of construction costs of the kind of home the average family is looking for to the median family income for the area in question.
