Hand made studio plan

This is my studio plan. We start today building block walls. Any advice?? I very worried about use HANGERS and I think I don't wanna use it. I think is better for me using absorver/wall units (basstraps, slats ...). Nevertheless, the inner steel framing walls are not builded until I'm sure that I'm in the righ way... Please help me. Or tell me the separation wall is not in the best place, or the recording room are so square sizes. Advices please! :(

are the door so next to the end of the wall?? there will be problems with corner traps?? How much distance there must be from the wall end to the door??

Try this cheers john

what are the brown areas? wall units? bastraps? corner traps?
