Here are a couple of white build prototypes. I wanted to test a new way of assembling the modules in case you want to take them apart again.
My idea is to use the raised platform part and cut out some alignment areas where the flaps of the other parts will help make everything come together right.
So you take the bottom posts part, lay the platform part on that, then comes the walls with the bottom tabs and finally the roof. All of these have these tabs on the underside which help to align and position the next module in the right place. Combine that with a "fold-flat" build version of the walls and you can take everything apart and store it in small space!
The only downside of this approach is that I need different platform parts for each layout I want to build. But as these are so cheap, fast and easy to build the advantages of this approach should outweigh the cons by far.
