I can make some Really good buildings in 1/18 scale for pretty cheap. (maybe $30 AT THE MOST).
And that would get you a fairly big house.
They would look like the ones in reds dios
.
They would be made out of blue foam board, but would be solid. I heat up the outside to crisp it thus making it harder and more ridged. I am not supper good at making them look "NEW" but i can make the look battle worn and really realistic. just teasing i can make good intact ones. For a little extra I would include custom furniture

they feel light but look great in dios
Would any one be interested?
I can post some pics if you want.
