I'm looking for some "flat" buildings for a micro layout I know Walthers have some N scale background buildings but it's mostly apartment buildings and I'm more interested in depots, warehouses and industrial buildings. Coud I use the front part of their modular buildings for example ? Is there any other manufacturer of such N scale items ? Any weblink for n scale flat buildings I can download , print and glue on a piece of cardboard ? Tia for any info.
