This is two houses I can't believe they built them so close together there can't be more than three feet apart.

It is like that in my old neighborhood in my hometown a lot.
It was all plans of identical houses that was supposed to be where the coal miners lived. So, they are almost identical half-double houses, and there was a yard in the middle that was also measured out perfectly.
Well, a few dozen years ago, someone built houses in those yards, also identical. So now it is house after house of half-doubles, and no yards, and everything is all smooshed together like that.
People have painted and done addiction and stuff, so it is not all totally identical - but I bet it used to be.
