New Studio Design - Help/Advice Needed

Hello! After almost ten years recording in my small space, and renting bigger studios to do some projects, I've decided it's high time to do something big. Now, or newer ;-) Here are the details: - I can build that studio from scratch. (Europe - Poland) - No noisy factors, no busy roads, airports. It's situated almost in a middle of nowhere ;-) - The idea is to build a great live room (maximum 80 sq. meters), where I can record rock/pop/live bands. - Live drum sound is my main goal. I want 3/4 iso booths (maybe special amp iso room), so I can record whole band with great isolation between instruments. - I have no idea how height it should be... - My biggest influences are (vibe, live room size) : Blackbird D, and East West studio 2. - I've attached raw floor plan with my idea of all my goals, but I didn't put any measurements of walls - Can someone tell me are there any good proportions that I can use ? - I didn't include any residential area, because I want to use 1st floor for that use. - I want to use wood, bricks, rocks as acoustic materials ;-) (no hifi stuff, just the real vibe ;-) Please - let me know if You have any suggestions about sizes of live room, iso booths, control room. I will read any post about that, and I will appreciate any comments, I know that If I will decide to build that studio I will need a specialist that will help me with acoustics, but at this first phase of designing it - please help me guys ! ;-) Thank You Martin
