my first post, help needed!

hi there all, what a great forum you have going here.was sent to this forum from another very popular board. im in a bit of a handling. I live in northern ireland and am in the middle of building my studio in my bad garden. I bought a 20Ft x 10ft portable cabin for my studio. Now at the minute, im giving it some TLC (small repairs, patch ups and a good cleaning) but it coming to the stage of actually building and designing the studio. I have been looking through some of the pics on this board, and my god, great stuff. Im looking to split the cabin in 2. Bear with me untill i describe my layout because i cant work sketchup yet. The door is right in the middle of the cabin, along one side of it, with a window either side, equally spaced out.Its lined with foam and a thin beauty board, wooden ply on the floor and thats about it. Now help would be great in any area of the build, what way do i split it? What do i use for the build etc. Ill be using it for production, mostly dance and electronic, tho a live room would be good to have. I also want to use the other room for djing porposes, to record mixes and maybe teach, so having that in the live room would be ideal. any advice, sketches etc would be brill. any more info needed, please let me know.thank you

some more info i guess i left out. I want the cabin to be as sound proofed as possible. I work to late at night, and tho my neighbours live a good 60ft away, i still dont want any trouble.lol, In terms of budget, well, i can spend abit, but nothing mad now, ya ere :lol: The window to the right of the door, i was going to block up and board over, this is where the studio will mainly be, with the other room as a live/dj room.I wanted a small hall way into the cabin??? god, im so not sure what to do about it. Like its a good bit of space, but really have no idea of a layout. any help would be just amazing, thanx again
