Pratical studio space

How's it going? I'm looking for some advice on how to lay out my studio space. Ive included a Sketchup file which I can't seem to turn into a jpeg, but anyway. The space is 14' wide, by 18' long, and needs to contain a control room, and a live room. In the sketch you'll notice there's 2 windows on the other side, roughly 5 ft from the right corner which I was thinking could be the control room. Above the space is the attic, which is not shared by the rest of the house, and a basement is below which contains the HVAC for the whole house. The live room needs to be able to comfortably fit a drum kit and another person or 2. It will also be used to cut vocals. My thought was to use the control room where the windows are for natural light whilst I mix or whatever, and use the live room between the control room, and the bathroom which I did not include in the sketch but is labeled in open space. So I figured the control room could be 9' by 14', and the live room would be the same dimensions. Is this a wise idea? Then I also thought I'd give the live space the 3 leaf design, as that would effectively also isolate the control room from the rest of the house. I'm not worried so much about the noise from the control room being heard outside and I generally can't hear noise from the outside in - except for the occasional lawn mower. Also please note this is my first time using sketchup, just tried today, so if there are things off, or information not included I should have I apologize.

Everything that you have planned seems to be pretty good until you get to 3 leaf. Why would you want to do that?? Have a look at the attached.

Yup! And that diagram only shows STC rating, which doesn't even consider the low end of the spectrum, which is where the real problems will be, and exactly where 3-leaf is really bad at isolating... - Stuart -
