Shepherdstown II
I like the coloring here. I think this may be the simplest "fix" is to link the 2 houses with something like this - that juts out a bit and is a different color. It makes an entrance to the house. It could create an upstairs bedroom. The cement pavers leading up to a cement front porch is a nice touch as well. Lighting is important.
Materials. Connector. Makes me think maybe its just not a "hall" but rather a family room? Library? Kitchen?
