"800-square-foot house..."
They can kiss my skinny posterior. I grew up in a 900 sq ft house because my father banked every nickel he made, not because we were broke. That's 2 - 180 pounders, a 200 pounder, and my mother, who barely avoided getting crushed.
I WILL NOT live that way again unless I have to. I know that's all some can afford, but if you can afford larger and want it, see my first line as to my attitude to government mandated teensy houses. Commies.
I don't think the anyone is proposing mandating small houses.
