Double Decker Barn

The term "double decker" is somewhat misleading, since these barns have three levels, not two. The lower level has stables for animals. Above that, the central level extends just one bay across from eaves side to eaves side. This tunnel-like effect creates space for a granary, and it also creates two deep "sink mows" extending from the stable ceiling all the way to the roof. Diagnostic features include a bridge on the bank side. This exposes a door that leads to the granary. On the opposite side, from outside typically it is possible to discern the three levels. These barns are most common in southeastern Pennsylvania; they generally appeared in the late 18th and early 19th century. Their tremendous hay storage capacity is evidence for the possibility that these barns reflect the surge in commerce after major improved roads created access to Philadelphia markets.
