Help for a "real" control room - italy

Hi all, i'm a newbie in acoustic and on this forum so "please be gentle" i have this little studio, untill now i've used the B-area as a kind of control room/all purpose room, without acustical treatment cause my little desk with pc, an onyx mixer, two PM2 nearfield and some rackunit doesn't give me much problems, so i just put the desk in front of the glass, 2 panels at sides and it's ok NOW we get some new gears, including a Soundcraft 600 console, and it's time to make a step on professional so i need some good suggestion to make B-area a good control room here some specs: -all measures are metrical -external walls are 25cm thick, sand-brick, so neighbours are ok -concrete ceiling is 3,90 with a mineralfiber counter-ceiling at 3,05 except on yellow zone where the counterceil raise from 3,05 to 3,80 (the window height) -soundcraft 600 is 1,15mt large per 0,90 -i use only nearflied monitor and a couple of consumer hi-fi -we are on a small city so we have to work on all genres from classical to deathmetal - what else ? ask me... and please excuse my bad english Tnx Max
