I don't know if this is possible, but maybe someone could point me in the right direction to find out. Our house is currently garage-less and the lot is only big enough to put a small single car garage on it. We want to add on and ideally would like to take some living room area and convert it into a two car garage, and then build up and back onto our existing home. Is it possible to build a garage over an existing basement, and if so, what is involved in creating the structural support system to carry the load of a garage? Thank you to anyone who can provide me with any useful information!
