I want to add a WWII style, 2 story Army barracks to my HO model railroad set that has an Army post theme. The closest thing I can find is a 1/72 plastic model kit. All my Army figures, buildings, and vehicles are HO scale or very close (I have some Matchbox cars displayed next to buildings). Would the 1/72 barracks look too large? If 1/72 is my best option for a barracks, would separating it from other buildings make it look better?
