I'm still playing around with the Hirst Arts construction elements. Here is a raised platform, with two sets of stairs on either side. With so many elements at my disposal, I am trying to find ways of using up all of the excess pieces.
The platform comes apart in four sections, and each is 3" x 3", which is my favored scale for 10' x 10' dungeon tiles. Using a scale of 1" = 3'4" allows for walls on the section, while still permitting two miniatures abreast on your typical hallway.
