Eh, it’s a lot more than that. But the paper is specifically pointing out that cost of land seems to be the driving factor, not cost of construction which is relatively flat.

A cheaper manufactured home would of course be nice if looking at costs, but dropping it on a $1.5m acre lot isn’t going to change the math that much.

Sure, if you are only building SFH.

I get that especially here people would love to think that "factory methods in construction" are wonderful, but the reality is that it is way more "human soul crushing communist block building" and far less utopian wonderland.

In defence of brutalist architecture, at least its functional, spacious, and sensibly planned enough to build communities around those blocks. The concrete monstrosities of the 1960 and 70s built in London are still standing and are worth just as much as the newer builds which typically sport newer materials but come with higher rents and smaller spaces.

In defense of the "human soul crushing communist block buildings", at least they were less soul crushing than living with multiple other families in the same apartment, sharing bathrooms and kitchens.

Post WWII there were an actual housing crisis in the USSR, and those block buildings helped a lot.
