Advice on Studio Layout

Hi guys, I'm pretty new around here and have been spending a fair bit of time the last couple of weeks reading through the 'stickies' and finding out just how much I don't know! Anyway, onto my question... I have a 'besser brick' garage (8.1m x 5.5m) that I'm planning on converting into a studio down the track. I've put together a pretty basic .skp of my layout and am just looking for some feedback on it. at 11mb it was too big to attach so here's a link to it: https://drive.google.com/file/d/0B8Op8s ... sp=sharing I've divided the space into a control rm, live rm and booth. I've tried to keep a few principles in mind with the design: *Minimizing parallel surfaces in the control room *Visibility between rooms *Balancing size of control rm / live rm to be able to record a rock band live but not be mixing in too small a space *Having separate spaces to use for isolating musicians when tracking I guess the feedback I'm looking for, is before I start planning the finer points (actual construction methods/materials etc.) is there anything I've overlooked in the design in terms of: *Practicality? *Acoustic design principles? *Difficulties with construction? *Anything else that will cause me headaches later? Thanks for your help - I'm just loving this forum! Regards, Darren
