The farm buildings including the octagon barn had fallen into disrepair and was in danger of demolition.
After the barn, historic farmhouse, garage and electric power plant were restored, other buildings were moved or built on the old Purdy farm.
New construction included a schoolhouse museum, a large multipurpose building, a covered bridge and a sawmill.
The Thumb Octagon Barn Agricultural Museum is open from May to October and the arts and crafts style Purdy farmhouse is open on selected days during the Christmas season.
