Thats a great thread Craig, thanks! Ironically, Im doing almost the exact same thing; building a studio in a townhome. My garage will be the live room and I have an adjacent room for the control room. Its been getting old having people telling me "ain't gonna happen dude".. so its good to see someone who is having success.
I found a room air conditioner that vents through a 4" flexible duct (like a dryer vent) so Im going to use that to keep the room cool. LED lighting seems to also be the way to go too.
Excellent, there is hope!
