How do you build a slab on grade on sloping land?
We are thinking of building a pole barn home in an area where there is likely to be bedrock if we tried to dig much. Over the 24 foot width of the home, the ground slopes down toward the south about 4 feet. How would we do a slab that provides thermal mass for catching winter sun rays in this situation? Could we potentially have 4 foot deep thermal mass on the southern side of the house half way through the house, and a shallower slab along the northern side of the house? Would this 4 feet of TM suck too much thermal mass? I imagine our home to be 24 feet from North to South and 64 feet from East to West. Imagine equivalent of 3 pairs of sliding glass doors on the Southern facing wall. Each pair about 7 foot high, and 7 foot wide... spaced evenly along the South for a rough idea. We live in Schuylkill county which is in East Central Pennsylvania. Thankyou, Adrienne
