Also just wanted to throw in that the actual base was simply constructed out of 1/2 inch foam core, then the floor was covered with air dry clay and the walls were then covered with light weight spackle, once dry I dremeled out the bricks and cobble stones. the front corner of dio curled up after the clay dried because the clay shrinks a little bit while drying. I meant to seal the foam core with a mix of water and white glue because I know that helps prevent shrinkage, but I totally forgot  ...oh well
