Hi! Help!!!! HUGELY appreciate Feedback.

Hey Everyone! This is my first post here and John Sayers, after reading many of the incredible posts and articles on this site I'd love to try and get some more advice tailored to my current situation. I'm a musician who records all my own music. I've made a record myself at my house with completely untreated rooms and am in the process now of converting a granny flat/barn type room into a fully functioning studio to record the next album. The space is rectangular and the walls are made from RAW MDF board. I've ripped up the carpet and am keeping the floor as concrete The room measures 7.95m long x 5.85m wide and 2.79m in height. the roof is also not flat (I've attached one picture of the room to this thread and also a crude photoshop diagram for reference. There are also Three windows which I plan on doubling for sound proofing purposes. Two of the windows measure 184.8cm Long x 93.7cm High (from the outer edges of the white frames) The white frame is 1.8cm in thickness and 6.3cm deep. The third window on the bottom wall measures 154.8cm long x 123.8cm high. there is also a glass sliding door in the room (as noted on the diagram) which I have yet to get measurements for. I'll be Monitoring and Tracking in the same space and would love advice as to how best to set up the room for these needs. I don't see their being much of a problem being in the same room and have no issues tracking with headphones on and simply using monitors for playback. I'll be recording all instruments in this space if possible - Vocals, Guitar, Bass, Drums, Pianos and all other sounds we can come up with! My bands music is fairly rock folk melodic based and bands within the same kinda sorta maybe vein we love the sound of are Death Cab For Cutie, The National, Elbow etc. Amongst the studio will also be a few desks and some furnishings to make the place a creative environment. another drawback is the necessity to keep a rather unsightly home gym in this room (the space is my inlaws and their only request was to keep the gym in there...somewhere... I would love some feedback and advice on how you would set up this room for the best result in sound/recording? I like the warm room sound of records like Tom Waits and Frightened rabbit but would love the opportunity to isolate as well. I Want to set the space up to be the most creative and effective technically it can be. Plans I've had to far is to build some DIY diffusors and also some partition walls in order to have some small separation of the computer and the tracking area in case of computer noise etc. I also thought these walls may be useful for isolating off a corner or something when needing a dead sound, the only problem is the roof being slanted resulting in an open top. I also want to get in some carpet and also some Large, freely moving slabs of wood to lay in the room to have the flexibility of different sounds (wood, carpet, concrete) when necessary. There is also a a small bedroom located at the other side of the room separated from the studio by a door. My budget is very small and I would love to get as much as I can done to make the room the greatest quality for $1000 or so, I can STRETCH but I'd love to know realistically what I'd be looking at. Sorry for the long post but I wanted to be as detailed as possible for you guys! I'm open to answering any questions and I appreciate all the help and feedback! Thanks SOOOOO much, Thomas.

Ive just finished painting and will be moving in furniture tomorrow! I'll posy pictures soon of my initial setup, I'll get to treating the room once I get some feedback from you lovely people! Thanks, Tom.

For only a $1000 budget, I would just plan on spending that all on acoustic treatments. I'm not sure how much "design" you could actually do in terms of building walls or sound proofing anything and still have money to treat the room so that you have a good sounding tracking and mixing room. Just take care of the early reflections for the speakers, build some broadband panels, Treat the back wall so you don't get a whole bunch of sound coming back at you at your mix position. Take a look at the DIY panel thread in the acoustics forum. Oh, I would set up your listening position so that the speakers fire lengthwise into the room, towards the bedroom. You could prevent flutter echo by throwing some plywood or mdf on the wall at a slight angle to avoid parallel surfaces. Or you could treat alternatng surface areas with DIY panels. Acutally, for sound proofing, I would look around the building the see if you see any places where there are breaches in the structure to the outside. Obviously if you see light coming in somewhere.. And seal it up with some caulk.

isolation - consider window plugs when you need them. also even musicians need oxygen to make sure you have a reliable air exchange setup - a couple of bathroom type fans to pull and push air with a simple baffle box arrangement may be enough. treatment wise - use scattered porous absorbers - 4" thick rigid insulation and cover with cloth. a bunch of 2'x2' absorbers scattered all over the room will help even out the room and keep it lively.
