Houses aren't even that "bespoke" - most homes come from a stock set of designs that builders bought 20-30 years ago and have simply been churning out the same house... There are so many places in America that claim to have different house designs and yet they're identical or mirror images of one another. Maybe one's got a different trim package or a different set of cabinets or countertops... but otherwise indistinguishable from one another. Stick-and-frame is still the most prevalent way to build homes for numerous other reasons though, like ease of available materials, roads being non-ideal for transporting large, heavy edifices, and the general perception of prefabricated homes being... not so great... due to seeing prefabbed mobile homes and the lack of quality that's incredibly common in that industry, amongst numerous other reasons. What has seemed to really change things recently are "SIPs" - Structural Insulated Panels - essentially prefabbed wall segments that you can then jinga together to make a home. They've become wildly popular in some parts of the country as they are easy to transport on the back of an 18-wheeler, easy to install with or without a construction crane, and take care of multiple construction steps at once, greatly reducing build times. They can often be more energy efficient too, as they have fewer seams and the insulation is applied more evenly (often an expanding foam is used instead of fiberglass, which also boosts the R value by quite a bit).
