I have some preliminary plans in pdf format, but they are only for a two screen. The final stamped/certified copies are only in large format. I believe the architects told me that nobody else could use them but me. Besides, mine are for a remodel/renovation not a new build. And, oh yeah, I paid $10,000 to get them, since it was a custom job. I don't believe theater plans will be as easy to come by as house plans. You can probably buy a set of house plans for a few hundred somewhere, but theater plans aren't just everywhere. Hopefully somebody here can help. Are you looking to expand, leeler?
