Dennis,
My under construction layout is in a slightly smaller space (11'x11') than Lew's (geysergazer), however, I do have a full 8-foot ceiling. It is around the walls too, but I had to put in an aisle on the one side for access to the two doors. So it ends up being 11'x8 1/2' with an area in the corner for a short stub yard and will have a wye to a two-stall enginehouse above the yard. I have wondered what the square footage of the actual layout is, so I measured and multiplied it out. It ends up being in the Mini category at 76 square feet. The shelves are 2 1/2 feet deep.
BTW This is the largest space I have ever had available, and my first layout dates back to when I was a teenager in the late '60s.
