I bought my childhood home from my dad and need to build an enclosure around the equipment and was thinking of extending it to have storage and it could be even used to change clothes in.
There is already an existing pad, with not much exterior room for the pump, etc. To me, ideally you'd have a pad that you could build walls on so it creates an air tight building. My dad originally started by setting 4x4's outside the pad to build something but never got any farther. My biggest concern would be frost heaving. I live in Michigan so we got all the elements and frost to deal with.
Anyone have any suggestions?
