Postwar planning laws and building codes made them a lot less viable. You're now always going to have to hire an architect and a licensed electrician and a plumber and so on - to the point that you probably have to hire a building crew rather than project managing it yourself - and at that point they have their suppliers and can handle that at a B2B level rather than it making sense for you to get one house's worth of everything in a package.
