So I'm hoping to convert most of my garage into a recording/practice space, but of course, there are plenty of hurdles. I'll post my thoughts and needs, and hopefully, somebody can help me address them.
My plan is to erect a wall between the laundry equipment and hot water heater from the rest of the garage, and put an entry door (or double doors?) there. This will leave an airspace of about 7' between the new wall and the wall between the house and the garage. Hopefully, this alone will help to keep some sound out of the house.
Next, I plan on removing all of the non-original bracing for the rafters, and framing for a ceiling. One of my challenges is that I still need storage space in the rafters, and I'm not sure how to accomodate this without causing a significant leak. I could put insulation and sheetrock on the underside of the roof to also assist in keeping sound out, but my concern with that is, will I need additional framework because of the extra weight there, as well as what will exist from the 8' ceiling?
Next, I'll have two walls to deal with, one is exterior and the other is partially exterior and partially interior (partly entryway in the house and partly porch/front yard. These should be fairly simple, I'm guessing, but my big problem is going to be the garage door.
Fortunately, I bought a thick guage steel door that is also insulated, unfortunately, the wife wanted windows in it. The other issue is that I cannot put a permanent wall in front of the garage door, due to city restrictions. I'm still putting myself at risk with the city because the wall seperating the laundry equipment is going to make the distance from the door to the wall about 16'5", which is shorter than my car (doh!)... but I don't think that will be an issue like a permanent wall in front of the garage door would be.
Next is ventilation. I want the room insulated enough to hopefully help with heating, but I definitely want an A/C unit to be able to blow cool air into the room. Any input on this is greatly appreciated, as I don't want to to just tie into the existing system for my home.
And finally, at least this is all that's coming to mind, I may need to house some cabinets on one of the studio walls for storage of misc items, and am curious what the best methodology for this is, so as to eliminate vibration/noises within the room.
On the upside, while I don't have a big budget for this, I *do* have more than a couple thousand bucks.

Any input is greatly appreciated. Oh, one other thing, what's the general consensus on this Quietrock material (
