Garage/Loft

Building must be designed to accomodate a 2nd story with living space, a comfortable (width) 2 bay garage which one designed (in height) to accomodate a hoist without the total building exceeding 24 feet. The structure is expected to be heated and contain 1 small washroom/sink as well as have room to store tools and items such as a tire machine (all on the first floor). Looking at anywhere from 40WX40H to 46WX56D. All of which should have a classic look to fit in with the barns on the property. Looking on an estimate as to how much this type of design project would cost?
