Hi Rise Buildings

I am testing some techniques for making high rise buildings that can be used on the inside for wargames and role playing games.  Sort of like a doll house with an open back so the figures can be moved around.  Here is a test for a second floor.  Paul Heiser Jeep and Airfix figure or size.

This is cardboard and foamcore board inside a small plastic crate.  The kind you store CDs or Blu-Ray discs inside.

I am testing different types of support for interior floors. I want it all to be modular and easy to take down and set up.

Here is the crate, it is about 7 x 9 x 6 inches deep.
