The EBE structure blocks are editable in any way you choose to make new ones.
So I encourage playing with these and see what custom shapes you can come up with.
Attached is an inner wall. Place the inner walls first, then surround them with the regular wall.
Place these in the EBEbank/_builder folder and restart Game Guru. New stuff you make is at the bottom.
P.S.
I also included a ceiling that will allow you to have different textures also.
Enjoy.
