My plan - Studio from scratch

Hi everyone, would just quickly like to say, love the site, even though I just registered it's been a good resource. Onto the studio. I've got a chance to build a studio from the ground up for the first time, and I'd like to get the things I can't easily change, correct from the start. I'll quickly share what I've come up with thus far and see if I've missed anything or need to change anything. I'd really like to know if my fundamental concepts are sound. I'm not constrained by building within a already built space so the possibilities are pretty open. In the basic floor plan (attached) you can probably see I've just used the control room design from the acoustics 101 booklet. Why mess with something so important when there's already something good out there eh? Anyway. The other thing to note is that I'm not terribly good at using sketchup or designing things accurately. The measurements for height width and length notated in centimetres are for the exterior walls of the recording room. Also, the ceiling of the control room will be angled 13 degrees front to back. Oh, and it says on the plan, glass sliding door, that's an old label before I'd thought that through. I'm now just planning on putting a single heavy door in place for the iso room and closet. Sealed and such. One thing I failed to do accurately in sketchup was seperate the two planes of the window between the control room and recording room. As you can see, with the recording room I've merely angled the interior walls to try and reduce parallel surfaces, and then decided to try and make use of the space with a small iso room and a storage closet. Hope this idea is okay acoustically and wont sabotage what i've tried to achieve by angling the walls? In terms of construction, I'm hoping to be able to float the floors, have the control room and recording room constructed on seperate foundations, and generally follow the construction methods and material choices set out in the acoustics 101 booklet. I'm not going to assume everyone's read it, so I'll attach images showing the ideas. I'm not a carpenter or anything by any means, so I have no clue about the viability of theses construction ideas, I would definitely be paying someone else to build it for me. One huge question for me with this design, if everything thus far is okay with the recording room, what should I do with the ceiling?! I'm assuming it shouldn't be parallel to the floor...Should I build a cathedral type ceiling then? Would it be possible to hang that? Would a builder turn blue in the face if I asked them to do it. Should I just angle it instead? I think I've covered it all. I just have one more question though I'm not sure it's entirely appropriate to this forum, anyway, with the materials listed for the floor, how would it fair with substantial weight? I don't know much about the materials but they LOOK kind of light in the diagram, though I'm assuming they're dense since they're meant to help sound proof the room. ANYWAY, I'm in a wheelchair weighing 160 kilograms with me in it. Will I damage it? Oh, and in terms of exactly what will happen in these rooms. I don't plan on recording just my own stuff, so noise levels could vary considerably. It would be in a residential area, so I'd hope the sound proofing would be sufficient for "loud" drums/amps during working hours, and sufficient for mixing (I don't mix as loud as some people) in the evening. I'm also expecting that this design would significantly reduce levels between the recording room and control room, so I'd get a pretty darn good idea what my mics are picking up. The purpose of the iso room being for perhaps a bass amp to be placed during live takes or just sounds that generally would be suited to a smaller room. Guide vocals would probably go down in the control room. Under the window is probably where I'd have my patchbays. However I haven't considered wiring a whole lot. I'm very ignorant in that area, other then to avoid things crossing as much as possible. I'd probably like to house most the cabling in an casing fixed to the wall so as to avoid cutting holes in the wall for power sockets and such. Phew! Cheers :) Antman

nice design. one thought - you could potentially break up that large angled wall in the live room into several smaller ones which could give you a bit more space. you could also then add some reversible panels around the room - absorbant on one side - reflective on the other - so you can change the room properties depending on what you're recording...
