Under 500 sq/ft for
familes?
Who are they kidding?
Shoeboxes for singles is fine & easily doable. And it’s just a maybe for some younger couples.
But please don’t try to say a real family with a kid or two will be comfortable crammed in together for years & years.
Yeah, there are exceptions that could stand it, but given how people are stressed & entitled in recent years, that 3rd world concept is dubious at best IMO.
