But how long will that last? Are we talking about just making a few dozen homes one a week and call it a day after we've given homes to 1% of those who need it, and having used up all the space within 100km of anything decent? Those homes might be tiny, but they waste space like no tomorrow. Besides, building a low rise isn't expensive nor takes long at all, yet is far more space effecient. Especially if people don't mind such small homes.

For the space of four of those units, you could build a single building that could easily house a dozen. Hell, just build a normal house and give everybody their own room, sharing the kitchen and bathroom. It'll be a nicer place to live on top of housing far more people on a fraction of the land. It's basically just a college dorm house at that point.
