Here are a few ideas.
1. Build the dio with all the buildings around the perimeter with action in a courtyard/street/square in the middle. All buildings could be open on the back side to look into.
2. Build each building with one wall removable. You could selectively remove them to look into each buliding.
3. Build each building with cutouts that are square and neat, as opposed to battle damage that is irregular. To further show a deliberate cut, you could either paint the opening a bright color, such as red (just like is done on a cut-away model), or you could actually frame the openings witha moulding and paint the moulding a bright color to make it look like a picture frame that is being gazed into.
4. Build each building with one wall in clear plastic/plexi glass to allow viwing inside. You could build a wall out of plaster, wood , or whatever as a master then vac-form the clear walls so they would still have doors, windows, brick relief, etc.
5. Lastly, you could combine all of these techniques to suite your needs in whatever layout you wish to make.
Good luck.
