Help Designing Small Studio

I'm happy to have found this site!!!!! Is the plan a sensible one? My maximum Ceiling height is 2.4m is it helpful to have it slanting knowing I dont have that much room in the control room. My floor is a concrete floor so I wont do any thing to it. There already is one wall I cant do anything to so i'm planning on having a 2nd leaf to improve on the isolation? Any Ideas or comments?

Concrete floor may have the best sound dampening effects.

And what would be your source for claiming that concrete is good at "damping"? :) :shock: :!: :lol: 8) :D Do you think it would be possible to use this special sound-damping concrete as the floor in mobile recording studio housed in a 17' trailer, for example? - Stuart -
