I wanted to post my finished pictures as many here have helped me in the process building this room. The advice and countless rooms to draw inspiration from have been key. Must say, I have had more fun planning, and building this room, than I ever could have imagined.
This is a single 13'x23'x9' room in the basement. It is hooked up to the central air but temperature stays between 66 and 70 degrees year round in this room without any help so I have the vents double closed all the time. There is an additional vent in the ductwork that can be opened or closed to help with sound proofing.
