I dont think i will put in the bathroom or the washer and dryer downstairs. I wanted to have maybe 2-3 rows of 3 seats. The rec room in the photo is a good size 12x22' and would be great If I could figure out how to work around the stairs. I guess I just have it in my head that the side walls should be solid with no doors or anything. Maybe I am over thinking it? Thought about just a straight wall next to the stairs the whole length of the basement, then split the other 2 rooms in half and enclose the furnace/water heater. Is it an issue to put a door off to the side next to the projection screen?
