Treating an unusual barn shaped studio

[Dplambe88]

Hi My names Dave, I have been using this forum for a while now and i really respect the service you provide for everyone starting out that needs help with acoustics... With all the people you've helped in the past on forums and all the guides posted for free on your websites, i have access to a wealth of information... The only problem is my room is not typical , its barns style with angled walls and very low ceiling, i have a basic understanding of acoustic principals but seeing how strange my room shape is i really could use some expert opinions on the layout, monitor placement and treatment. I have a decent measurement mic and room eq wizard so i can do the fine tuning but i just need a good starting point and some fresh ideas.
The studio is a one room for recording and mixing all kinds of music from acoustic to hard rock but it will be mostly for recording jam sessions on full live bands so it will need to be versatile. Its constructed with fluffy fiberglass insulation behind 1/2 Sheetrock with a floating laminate floor. Its located in a quiet neighborhood so isolation from the outside isn't too much of a problem. I'm not interested in building any double walls of loosing any space so its not really a priority, however the windows are single pane so i was thinking of making some panels i can place over them while tracking... im open to ideas..

LAYOUT .. I need advice on the best way to setup my room, not only for acoustics and speaker positioning but also workflow. the room is an all in one live/control room so it needs to have treatment for a critical mix environment as well as drums, guitar and bass. i illustrated in the attached pics where everything is with my current setup but i intend to move whatever pending your suggestions. Its a Nuendo DAW setup so the large mixing board in the pic is for monitor mixes only so it doesn't need to be within the speakers sweet spot .My biggest concern is that the room is not symmetrical , one wall is 63 degrees and the other has had a closet build onto it making it 90 degrees. I cannot remove the wall that makes up the closet so im not sure what to do. I currently am planning on building a plywood wall to fix the symmetry around the mix position. im looking for advise on how to treat the front and behinde it. . My other concern is my monitor placement , i have 2 sets of monitors , focal cms 65s for my near fields on the desk and a pair of Yamaha hs80ms on stands for reference near/mid fields.

TREATMENT....Currently i have a whole bunch of auralex 1inch foam, 20 or so OC 703 2" rigid fiberglass all wrapped in fabric as well as (2) 4" thick 2' x 6' rock wool and (5) 4" thick 4'x4' rock wool, im not sure the density or brand but it came out of pro studio so it probably decent stuff. i understand the idea of the reflection free zone and im assuming i need clouds due to the low ceiling. My concerns are what type/thickness of treatment to use for what and not making the room too dead for drums. Im also curious as to how i can use the empty closets and to opposite small useless angled corners of the room for some serious bass trapping. Finally is my room is big enough to benefit from a skyline type diffuser and if so what frequencies should it diffuse?

ROOM SIZE 15'5"x 19'4" and is 7' 6" H ....the large wall is angled at 62 degrees and the other is a right angle, the ceiling angles are both 28 degrees. the large empty space in the sketch is the stairs coming up witch are 3' 7" wide

I would greatly appreciate any help or ideas anyone can contribute. And Please feel free to edit/rearrange my sketchup file if you have the time. thank you OFFICE.rar

your basic layout looks good, with the speakers firing the longer way down the room. For treatment you'll do the same as every other room. Bass traps in as many corners as possible, and absorption on surfaces near to the mix area and instruments, and above drums etc. Adding a wall for symmetry around the mix position could help, or you can just make false walls with rigid fiberglass to match the other side. One-inch foam is not up to the job, but you can put the sheets face to face to be thicker and more "solid."
