This is a big problem in The Netherlands. I want to buy a plot of land to build a home but it's always attached with a huge list of requirements. The home needs to be between A and B cubic meters, ridge height C, gutter height D, roof angle E, front needs to face the street, house needs to be perpendicular to the street, brick needs to be color F, needs to have parking for two cars, heating through system G.

I'm a big fan of prefab sustainable homes, the wooden flat-roofed bungalow ones that you can plop down from a factory in about two days. But those homes never meet the requirement list.
