long studio "existing cr"

I have a room that measures 25 feet x 14 feet and has 7.5 foot ceiling. There is an existing contol room in my bedroom which has been mildly acoustically treated (the bedroom shares a 10 foot wall with the intended recording space) some walls are still to be constructed so doorways are an open topic any suggestions are welcome and very appreciated i am thinking of putting two iso booths at the end of the room with angled walls ......

A drawing would probably be worth a thousand words here.

im having trouble with the image thingy but here is a link to the basic pic i am thinking of mabe incorporating the cr into the new room as in the plans for garage studio 1 on the sae website http://www.saecollege.de/reference_material/index.html sorry about my img difficulties
