I think that's outdated information. Most houses are built in big lots, with each house being mostly a copy-paste of the others with some cosmetic tweaks. Hell, they probably have software to mix and match cosmetics too. Then the housing lot is likely a clone of a lot the company has built in dozens if not hundreds of other locations.
That said, prefabs would help greatly. It's too bad that prefabs would have to travel over the open roads, which limits the size. If houses could be lifted via helicopter to the destination, we would likely see costs fall greatly, through the power of the assembly line that Henry Ford invented oh thousands of years ago now.
