IMHO after thinking about this and going back and reviewing the construction details, It would be far easier and cheaper to just strip out the insides of the theater down to the drywall and reassemble inside a new room built to the exact original dimensions. Think about this 16 ft wall over 8 ft tall, first it won't fit in any door except a garage door. It has overlapped double layers of drywall with Green Glue. It will weigh about 750 lbs so loading, unloading and transporting it isn't going to be easy. Then you need a pretty big truck. It would far easier to run down to the store and pick up some faming lumber and drywall and throw together a room. That way it would also fit in someones basement as the inside finishes can probably fit through a door and down a stair.
Also recall that the walls were originally one height with room within a room ceiling joists added at the top. Later it was decided that the room should be taller and the joists removed, Drywall and GG was added to the original garage ceiling and short wall sections fitted on top of the original framed walls. What this means is that the room comes without a ceiling, I know small point but another argument for just starting with a new wall and ceiling built to correct dimensions.
I think Ruben is looking for offers, Anyone buying it, I'm available for hire to try
to put it back together. I do have a passport.Edited by BIGmouthinDC - 7/15/12 at 10:55am
