Live room rescue!

*Raises hands in surrender* I agree about angling the walls, this was the rough idea they had, and I am tryig to learn the Qcad software I was using. The reasoning behind another two booths is : 1) the current boots are very low ceiling, and the cieling is just 1/2" drywall screwed to the joists . ( no I was not in the lop during construction reallt, and when i did show up and suggested things like doubling up on drywall leyers, i was told by the then management " well, we arent going to do that.."There is now new folks in charge and they want to make the room useable without flushign the current space down the tiolet and / or spending unnessacarily. 2) they really want ot be able to record a smallish band live, and have seperation between acoustic guitars and drums, etc. my thinking is that if the two new booths are built properly, they will serve as isolated spaces, there are no neighbors, so as long as it isnt thundering or raining hard outside the iso between the other larger room and the outside is not as critical to them. 3) the origianl "design" ahd two iso on the east wall that were seprated from the big room by sliding glass doors ( stock home depot doors) that offer next to zero TL. My thought is to maybe make the top iso slider into a proper wall with smallish window and use the bottom iso as an airlock/mic storage room ( also losing the slider) that way one of the two isos becomes somewhat useful and there is not a wall of glass there for no good reason. The larger space would be approx 15 x 19 ( dependign on what you all fell is best) and have a cieling that is vaulted from approx 8' to 14 '.. Again Thanks for all the help!

So you are looking at a room like this? cheers john
