> In the US, price per square foot is an important metric for appraisal. If the appraiser puts too low a price on the house, the buyer can't get a loan. Therefore if you are building in the US to sell the house, then you will maximize the square feet to maximize the appraised value.
Something in that paragraph doesn't add up. 500 sqft/$500k property is $1k/sqft, a 750 sqft property needs to be valued at at least $750k to be the same price per unit area; bigger is not sufficient for more per unit area — my expectation would be that cost is sublinear with area for most residential units due to various fixed costs such as (an assumption on my part) utility connection fees and architecture fees.
Mid scale development, entire districts at a time, I'd expect that to be linear with regard to area (so the derivative, cost per square foot, is constant); Very large scale, an entire city at once, that I'd expect the derivative of cost with respect to area to increase as size increases, due to the expectation that infrastructure becomes a dominant cost.
