The Granite Barn is a circa 1870 tie below the plate frame and is completely lofted over for a second floor (with  3' 6" knee wall.)    The four bent frame is 28' x 30'.    It is a very basic later era frame.   There are studs and common rafters between the bents.   There are both sawn and hewn timbers and several of the hewn timbers have been repurposed.
