I want to seat about 10 people max, use a projector to get the big screen, have the option of using 7.1 audio and that is about it. I am house hunting right now with a basement as a requirement. So I need to know the minmimum dimensions on the basement. I also went with a front projector because my theory is that with the lack of depth required for a rear projection tv I gain a foot or two in the room from screen to viewer. And is their a glossary of the construction terms. IE what are staggered walls.
