I built my layout to go around the room so I wouldn't loose my whole basement to just trains. (a good idea but not practical for everyone else) I had to make 2 lift outs so that family traffic to the laundry and workshop is usually unimpaired. I made a shroud for the furnace that resembles a station. It's on rollers to get access and the trains can go behind it. The wall painting idea was a first for me but I thought ...Why not? I can always paint over in a basement. 072 for the two upper lines and 031 for the lower little town area. Recessed lights in the low ceiling look good when dimmed with lighted passenger cars running.
