New Studio first time builder any help would be great!

Hello everyone, This is my first attempt at building a studio. We bought this house specifically because it had a fantastic room for a studio detached from the house and behind the garage. We have no neighbors around us and and all commercial behind us. The space I converting attached to the back of our garage. The ceiling is vaulted from 8' to 10', The inside dimensions are 11 feet 6 inches by 31 feet 6 inches. The floor concrete slab not sure how thick, with no posts or supports (completely open) the concrete foundation comes up about 3 feet. I have a limited budget about $6000 to start and would love to leave room for improvement in the future. I am looking to build a control room, iso booth, and tracking room. I was planning on building all new interior walls and leaving a 4" gap between all new and existing walls. The biggest question I have is float the floor or not? In my situation I'm not too concerned with eliminating vibrations through the building but more concerned with isolation between each room. At this point I don't believe my budget allows for it but may reconsider upon recommendations. I was hoping to keep the control room closest to the house as to provided a little more isolation from the tracking room. The problem with my current design ideas is the entrance from the garage falls in the back corner of the control room. How might I solve and problems in this corner if there is an entrance there? All ideas are welcome I have included two skp files to show the layout of the space as well as my initial idea for the three rooms. Thank you in advance for any help you can provide.

Given the space available, I think you shouldn't consider more than two rooms. Unless your realy need a tracking room AND a booth, take a look here : John Sayers - Lumisuto studio

You have ~340 ft2 and a $6,000 budget. This seems unrealistic. Andre

I should have said that I am looking to do this a little overtime. My business right now consists of live recording and at home editing. I am going to start with the control room so I can accurately mix my live recording and do some voice overs. I plan on having a lot of voice overs so thats why I was hoping for a iso booth. However I like the design of the Lumisuto studio, Would a portable break down booth be a good alternative? As far as my budget is concerned I would rather build everything right overtime, than sacrifice acoustics and isolation in the beginning. My business currently does just fine as a live mobile recording business. My biggest concern at this point is acoustics in the control room. thanks again Mike

If you do voiceovers, a larger room with dead acoustics is much beter than a small vocal booth. Rather than the vocal booth, make your main room larger with variable acoustics. Much more variety and better sound for voceovers. Andre
