I tried to sketch out a plan for the palace building, I found this could be potentially very large and make for storage problems. Another problem I thought of was if the rooms had ceilings then taking photos might be tricky. So initial concept is:
1. Exterior - A low relief model of the front of the palace, main entrance with portico and some part of the gardens.
2. Interior - build separate rooms, corridors (with optional ceilings), easier to work on and also makes it easy to add another room if I think of one. Also these can be stored more easily.
I'll be trying out putting a clear plastic base on a spare figure next.
