Thought I would post a link to a few pictures of the home theater area I have created.
I sectioned off a corner of my basement and built a new wall along one side to enclose the 3 walls that were already present.
I built a stud and drywall wall and ran some electrical for lights and the projector. I think the room measures 12 feet wide by 22 or 23 feet deep.
The projector sits on the floor and projects up to the screen. The keystone correction causes the bottom of the screen to be a little blury but it isn't noticable during movie watching.
I will add additional pictures when I get a chance.
