How to make this VERY un-square room usable?

I have this room, currently un used that i would like to turn into a decent sounding mixing/line-tracking space... i've already done a concept in sketchup of how i think the space could be used, but sound-wise i'm a little stumped as its not at ALL symetrical and i don't really know where to start even basic thoughts on where to place things would get me started, i'm happy to do the maths on rt60 and standing waves etc once i've got a goal in sight! here is a visual concept, and the dimensions... please let me know if i've not provided enough info, thanks in advance! and here is a link to the sketchup file in case anyone wants to go to town on it... http://www.cmproductions.com.au/studio/ ... orPlan.skp

smidge - could you offset the strange corner by turning it into a vox booth like this?? cheers john

wow! that is what i originally had in mind, only i was worried i'd lose the natural light through the window, which faces out into a well lit foyer area on the 1st floor... and a vocal booth would be PERFECT for this situation if all goes well something like this will definately be built, i'll go through and do some more measurements looks great, now just need to try and work out how to make it sound great!
