Control room size? (again)

g'day, sorry bout the double post thing last time, dont know what happend. any way i'll re-inform my situation. so here's the deal, ive got a 3 bay garage going up and i can have one bay for a "studio" its got a dividing wall for my bay. and my dimensions are 6m x 3m (just realised you are aussy! good to see!) I'm pretty sure i can only fit 2 rooms, control and live room. just wondering how big to make my control room? ive read that you shouldnt have your control room wider than long or sqaure for acoustic reasons?? any way i want my live room big enough for drums and the control room to fit a comfortable 3 people inside. ive got this plan of the sae website. could you suggest any changes or something different i'm up for any suggestions? the garage is a metal one, do have any suggestions concerning this? i'm not worried about isolation at all out of town nice and quite! cheers mate, Nick, - Shmack Industries-
