Great question and it seems you may have come up with a good solution if you do not mind
loosing the garage. There is a house on the corner of Union St and Davis Rd that put a second
floor above the entire house. This could be a valueable contractor to get in touch with. Like all other
projects like this, get at least 3 contractors over for a quote and get their ideas and input. You are definitely on the right track to seek out ideas before the decision. Good job and good luck! Keep us posted.
