New Studio Design - Help Appreciated

I'm from Oxford, Mississippi and I am new to this site. I am attending the University of Mississippi, and am hoping to become a recording/electrical engineer. Although I have some experience as a musician, I am just starting to learn about recording. (I am a guitar player and I enjoy playing all styles from bluegrass to blues/rock, and hope to record a variety of styles as well.) I am trying to transform a room thats 13'6'' x 19'8'', into a home recording studio. I know this is not much space to work with but I would like to be able to get the best possible recordings in such a small place. Instruments I would like to record individually and live together are drums, bass, guitar, mandolin, banjo, fiddle, and keys. I am working with a fairly small setup: a Mac Pro, a 003, Event monitors. The budget I am looking at is about $4000, and that it can be more or less if necessary. I did a sketchup representation of this room shown below. The file is too big to post though so I attached an image of it. First off this house is way out in the country, so neighbors are not really a problem however outside noise could still be an issue, such as logging trucks, etc. The outside walls that have windows are standard 16 OC construction with insulation and sheet rock. The windows are double pane insulated. The wall thats leads in from the kitchen used to be an exterior wall, and is 8'' thick. The doorway is approx. 16'' off the floor of the studio. The floor is concrete slab with linoleum tile, and the ceiling is sheetrock with 8'' insulation. The smaller whole on the same wall as the door is just an opening between the kitchen and the studio. There are several questions I have: My original thought was to have a control room that you entered when you came in the door from the rest of the house. I would have both the control room and an iso booth at one end of the room and then leave the rest as the main room. But is the room too small to do this effectively? I am open to any suggestions that you might have. If I add walls, what are the appropriate angles to use? And what should I put on the walls and ceiling for acoustic material? I was going to put another sheet of glass or plexiglass on the inside of the windows. Do I need to do something more than this? Is there something besides carpet that I should add to the floor? Thank you VERY much for your help.

maybe a simple split would work?

Yes that could work, but I heard from some people to leave it as one big room. I am not sure which direction I should go, because the drums will take up a lot of space if I split it. I was wondering how to put in maybe an iso booth or amp room? Also, what should I do since there is a step down from the kitchen, possibly make the control room in the corner where the door is, and have it higher than the mainroom?

it is possible to leave it as one room and add a booth, esp if it simplifies the overall workflow for you.

The workflow is not a big deal, I just want to be able to record vocals, along with like drums and amps at the same time. Do you think I will have enough room to have a control room, live room, and a booth? I'm just getting into recording, so its hard to comprehend all of this info at once and make a reasonable decision. Is it okay to record a guitar amp relatively close to a drum kit?

if you leave the room open and make a vox booth, then you can use gobos to help partially isolate the instruments and amps in the room. depending on what you're recording, you could have the guitar DI into the board and reamp after the drum tracks are done. this way you get the performance together and there's less problems with loud amps near an acoustic instrument. all depends on how your clients want to work.

Awesome, that makes sense, so lastly what about more than one acoustic instrument, such as two guitars and vocals at the same time? should I just move them as far away as possible? Or if I build a booth, put the guitar in the booth and vocalist/guitar outside the booth?

So here are a couple designs that I made in sketchup. Would either of these designs work well or should I just go with one large room? For the most part, I will be recording myself until I get experienced enough to record full bands, so it would be okay to have a one room situation. But it would seem that a split would be more helpful in the end. Also, is it even possible to soundproof such a small space? thanks
