Nathan, I'm coming in pretty late to this thread but I designed/remodeled a studio for fellow slutz member "The dman" (do a search on that user name) to his roughly 24 foot by 24 foot space. Since your space is very close in size to his I suggest you give him a call and maybe he will take some measurements and give you his wall layouts (I don't have that info anymore). It's a control room/live room/vocal - iso booth/mechanical room layout with symetrical splayed control room walls that has fantastic talent views (windows between control-live, control-vocal, and live-vocal) so all rooms can be used by a recording band. With standard wall/ceiling treatment the rooms turned out great acoustically and from a working/traffic-flow standpoint he is very happy with the layout. Here is a link to his webpage with a few photos and his phone number.

When he got rid of his analog desk I also designed the desk/racks and he scanned the plans so if interested he would probably give you those too.
