Help with basement studio design

My basement is approx 2000 square feet with a height of approx 7'8" to the bottom of the rafter. The dimensions I have to work with are approx 18 wide by 38 long. Need to have a live room big enough for my band to rehearse and record but a control room big enough to really mix. I use pro tools, used to engineer for a living so my equipment and skill level fairly advanced. I also have a reasonably large budget. That said, this is just for fun now. The basement is fully dug in, new construction (2001). My biggest concern is ceiling construction, proper dimensions, and hvac. Blocking sound from going through the ceiling a top priority. This is where I need help. I don't want to give up too much height. Also hvac. How do i provide cool air in the winter? I can't run both, so do i put in a separate system? I"m in lower Ct, don't think i'll ever need heat, and if so I'd buy portables. Any help in proper dimensions, types of walls and especially ceilings would be appreciated. I bought the latest home recording studio handbook but my constructions skills are weak. Thanks

please complete your profile with location etc. sounds likes a nice sized space except for the ceiling height. there are several options for HVAC including split systems which can provide cooling and heating (lookup the Sanyo units) but you'll still need fresh air and you can build/buy some isolated vent units to manage the air exchange. the ceiling - for true isolation there you're going to lose some of that height. you'll need to build up the mass on the upper floor and you'll need to use isolation clips and hat channel/furring strips and drywall, or build nested ceiling joists supported off your inner isolation walls. in order to even being designing anything like this, we'd need a detailed floor plan showing the doors, windows, stairs, plumbing, ducts, utilities, etc down to 1" or lower accuracy. there are numerous occasions where we start a design and then hear, oh, we cannot put that there, there's a _______ (fill it in) that cannot be _______ (blocked, moved, used).
