Floor is concrete, carpet pad, and carpet.
The reality of another layer of drywall is hitting me, because the baseboard/door/window trim would have to be redone. On the other hand, if I do add a new layer, I'd have the luxury of wiring some wall sconces. I hadn't considered this an option before, but if I'm starting again from scratch (already having painted all walls/ceiling + installing the screen), it would be an option, albeit more expensive.
New question: With a new layer of drywall, how are the existing elecrtical outlets incorporated?
The major factor in this is cost. This isn't a single family detached home, but I did buy the place specifically for this room. If I can have a layer of green glue and drywall installed for a good price, I'd have to seriously consider it.
