Evening..Has anyone remodeled and existing garage to incorporate a room addition? We are looking to increase our square footage keeping costs down by not having to add a new roof and foundation to our existing home. There would still be some challenges I assume in lowering the existing garage ceiling {that is high} and creating new access for room and home entrance that is on an upper level. Garage is on a large slab with a concrete cinder block foundation that appears to be very capable of withstanding extra materials weight however I am not an engineer. Probably would have to add a sky light and window that I can see..I have attached a photo...garage is considered attached due to breezeway roof line. Any suggestions or experiences with like projects would be appreciated. Thanks..
