I need some guidance. My husband and I own a 1965 1,200 sq ft ranch in Millbury, MA. We now have 2 children and barely fit. Our house is not only small, but a "home owners special". In any case, we are looking to make our home more of an open floor plan. However, that requires some work with the load baring wall and altering the height of the roof. Is it possible to do this alteration, change the height of the roof, and still leave opportunity for us to build a second floor years from now?
