How do I add a garage to my split without over powering the house? I need a room over the garage too so it needs to be two stories. Driveway area sits a little lower than house. Do I create a breezeway then bump back, turn, move up or a garage? below: The green house is what I am going to do w the exterior and then compliment a garage to it. My house is the ugly yellow one. Any pros out there...I'd love some advice!
