It will work with no furniture in the room. If you want some shelves mount them low or higher then normal so you dont bump them with your cue.Also if you want a tv or stereo in there mount it extra high. For your table light if you are going to mount one put 50" above the playing surface of the table this will give you the best light and you wont hit your cue on it as much
I have the same problem my are is 8" to narrow and I use a 60" cue..
