Right? And also...who needs space between two homes if there are no lawns? Just moosh all the outer walls together.

Come to think of it...that's gonna result in a ridiculously long line of houses. Maybe we could moosh roofs and bottom floors and stack 'em up a bit to make the line of houses only a half to a third as long, and then leave a little space between Consecutive House Stacks™️ - y'know, so that there'll room for more windows.
