No, I didn't fix the uneven walls (which I probably should have... I'll get to that shortly...) but I did add a back door and a walkway from the garage. In so doing, I moved the tree further away from the back wall, moved the water heater into the Laundry room and moved the heater to the back wall. Oh, and I removed the railing from the back porch.
