The picture on the left is just an argument against lawns.
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.
