Two more images.
Reckon where the combine gates are, I'll actually open that up a bit as an extension to the street, which would form the last serious chunk of horizontal expansion to the map.
Outside of that, we go vertical, likely by one more legally accessible layer up. and a legally questionable layer down.
Any more additions to the space that increase the horizontal size would likely just be smaller paths to grant a bit of privacy, or connect up and down again.
Single street gang?
Or, two overlapping streets gang. I guess.
