I forgot something in my plans: tons of people live alone or will. Divorces, couples without kids, younger generations scared to love so they end up on their own for a long time… Plenty of social patterns that are not going to fill pretty big family houses anytime soon.
It’s OK! That just means that the subdivision would be smaller, which means a denser density akin to SoCal, but also less spread than the acre plan was creating. I can work with that.
