I need help with a plan for an addition to my almost 100 year old home which sits on dual level terrain created by limestone escarpment. To complicate it is also partially in a DNR  setback zone. I have a basic design which can meet the setback requirements, but i am having trouble setting it on the "dual" terrain. What I need is a finished design,  a site plan, a foundation plan which can be converted into builders blue prints. Can you help. I can provide some elevation data and the current design I have worked up.
