So I am trying to build a complete tongue-in-cheek 19th C British theme. You can see more images in the Victoria! gallery.

Currently working on the Working Class terraced housing. I'm using props to allow each of the two houses per cell to stack on hills in a more realistic manner. 

Anyone want to give an opinion as to which chimney configuration looks better?

We have Cell-Side chimneys in the first pic, and Cell-central chimneys in the second.

IN my opinion, the second looks better somehow, the chimney-tops dont end up fighting with each other.
