I had considered another approach, which was relatively thin 3D buildings. These would enable a number of buildings to be fitted into a small space, giving a village/town feel, but being thin they can be arranged around the edge of the built-up area when troops occupy it, without taking up significant table-space and getting in the way, thus still giving the occupied area the look of a town.
Today I made some buildings.
I used the Junior General buildings as a basis, but they were mostly constructed in MS Word, using tables. The Junior General facades were pasted into the various cells. This makes the design easy to mass-produce, and folding them and sticking them is also quick as well.
Here's a small villages:
And here it is occupied by troops:
Each building is only 1cm deep, plus a small base for stability, so they will not significantly get in the way of troops moving around outside of the village.
I have used a spare roof piece to show how the gaps between the buildings could be covered by barricades - easily scratchbuilt in a number of ways.
The next stage is to fire up word and come up with a design for a church and some other public buildings.
For those that are interested, this is what the buildings look like in Word:
The roofs are a separate page.
