Thanks, DKS. I see any front needs a cornice. I'm going for 4-story buildings so I'll just chop various walls to stack over a store front, then add the cornice. Only need one building like that.
I also made a "Sears Department Store" out of bashing/rearranging the hotel. In that case the fancy walls go only partway down the sides, and the back half of the wall is plain windows/brick. Not ready to show it now, tho.
The best thing about sticking buildings together is it frees up all the sides for other uses.
