My building table is a 7 1/2 ft x 2 1/2 ft x 3inch hollow core "thing" The neighbor who was going to throw it out before giving it to me told me it came from the receptionists counter at some commercial building. My building area is about 20' x 8' and since I do not have room to walk around, the work table comes out to a couple of saw horses in the driveway when needed.
