suburb-style single-family tract housing isn't sustainable. You can live plenty comfortable in a large courtyard apartment as you would in a house, and bonus is its more efficient and environmentally sustainable to build that way
We live in rural America surround my forests, empty fields and agriculture. We have more land than we know what to do with. It's surprising that every commenter here made assumptions about my situation.
