In 2002, the architects Bohlin Cywinski Jackson of Pittsburgh were commissioned to create an adaptive reuse of the Barn at Fallingwater, using the original characteristics of the barn itself. For example, in the large threshing room located in the upper barn, the architects kept the initial gaps in the vertical siding, which were once used as ventilation when storing hay. This helped to preserve the historical space and also made the space more functional.
The Barn is a converted historic Pennsylvania bank barn, located about 500 yards north of Fallingwater at the entrance to the Bear Run Nature Reserve. Several distinct settings, within and around the building, are available that can be used to create the perfect wedding ceremony and reception.
