Hi Just looked at the pics again - arrgghh - didn't realize that the entire wall was mirrored! I thought it was a small mirror on the right, where your camera flash is For sure you could use that room for HT, removing all the mirrors on the wall Sorry about that
I think the first 2 options are for TV only - I don't see an HT option there The last option (game room) I think is your only option The patio doors will have to be covered, but that should be fine
