Help Needed - Control Room/Booth

Hello Guys, This is my story in a few words: I was going to build a great studio in my house. My current living room that is towards the garden was going to be the control room, and the live room, was going to be built from scratch in the garden. A few days ago, I was told my house is going to be sold, not tomorrow, not next year but maybe in a few years. So, its not worth spending all that money into the studio knowing its going to be destroyed anyway in the near future. Soooooo.. Because of that, i decided to build a much small and cheap live room, just enough to make some noise and have the luxury of having a recording room separate from the control room. Its not going to be THAT cheap tho, but much cheaper than the "original big live room project". The thing is, i'm not even comfortable spending that amount of money for the smaller live room anyway (about 20k), so i got an idea: OK, i wont record drums, but I have to record at least, loud guitars, bass, and vocals. So, i thought "how about if i make a small booth inside the control room". My question is, will that work? Im talking about a room thats big enough to put a 4x12 cabinet with a mike stand, no more than that. That booth should be pretty dead. but i must ask you guys, if its gonna work. Can i get GREAT guitar sounds in that room? (no,i'm not interested in room sound for guitars so far) I record mostly rock, so i'm looking for dry, punchy distorted guitars. And also, how in the **** can i isolate it? Thanks in advice and whatever other idea is welcome PD: This is a plan for the second design(small live room) The control room is the one at the bottom-right. And its almost 50 f2. Its not a square, in the plans looks like but it has an extra part where the glass is clearly shown THANKS!!

Actually, If any of you guys have any other idea about re-designing the control room space so i have a small recording room with a glass and everything would be great ! The largest in the control room (as u can see in the plan) is 15 feet. By 12 feet wide.. And almost 10 feet height (3 meters) THANKS!! pd: thats the best i can do, i dont know how to sketch up:)

maybe this is more practical, a viewable image.

Thanks man. This is the current living room

it looks like you could out an amp cabinet in the airlock on the upper side of the CR, and perhaps open the closet (?) on the bottom side and use that as well?

I'm sorry about not giving enough info The rooms at the bottom of the living room are a bath room and another room separately from the living room and cannot be used. All the plans to the RIGHT of the living room is the liveroom/vocal booth i designed. There's nothing in there already. So the only thing available for construction is the part towards the right (garden)

maybe flip the room to face the garden and then build out the garden area with a nice isolation booth (suitable for amps, drums, vox, etc...). maybe 5m x 4m and use it for however much time you have there. maybe if its built to double as a garden tea room, the owner could help pay the bill.

Thats what im doing right now (sorry, I meant the "left", my original pdf is backwards) I hope this is a better picture of what is my design. (sorry, i suck at photoshop, sketchup or whatever) So far, the live room thats shown on the plan costs about $20k, which is a lot for me. So far i'm doing it it but if you have a cheaper idea would be great. Thats gonna be built from stratch and the layering so far is 1 layer of concretefiber, which are similar to concrete and ready to install (like drywall), a 30cm air space then 2 drywall layers, I'm getting like 65-70 SPL right now. Brickwalls are not an option since I need more handwork (i'm not building it myself) and thats expensiver. THe floor is already there where the live room is supossed to be, since it is a space where we have a garden table and chairs (so no need to do the floor from scratch, we are building the walls and everything from there) Hope that helps
