Without reading all 47 pages, this (below) seems to be the crux of what it is talking about -- cheap, small factory-built single family detached homes. And I am skeptical because my research suggests we don't need crappier single family detached homes. Instead, we need more missing middle housing and similar. It’s clear why these homes are a threat to those constructing stick-built homes, especially in the lower-priced home market, and why monopolies in traditional construction have invested so heavily in blocking these small-modular homes. The homes are of high-quality, built to a strict national building code. They are manufactured at a cost per square foot that is one-third to one-half less than the cost per square foot to construct homes with traditional methods.4 Not only can factory production methods produce houses at a fraction of the cost per square foot of traditional methods, factory methods are also able to “go small.” That is, factory methods are able to economically produce homes of small sizes.5 The average size of these homes (in square feet) is less than one-half that of homes constructed with traditional methods.
