The crawl space under one end of my house,about 15'x15', is on the downhill side. It's been dug out and cinder blocked. I have to duck my head a little but with a heater and a 32" TV with cable, it works for me. I hate the cold. I go down there when it gets below 60F or above 80F(stays much cooler in the summer.) I call it The Dungeon.
