English barn

The English barn, or three bay barn, is a barn style that was most popular in the northeast region of the USA, but are the most widespread barn type in America. This barn type is, with the New World Dutch barn the oldest type and has been called the "...grandfather of the American barn." New barns in this style were constructed for over a century, from the 1770s through the 1900s.
Design.
The early pioneers brought with them a barn design inherited from the first colonists. An average English barn measured thirty feet by forty feet and had a large double wagon door on its lateral side and unpainted vertical boards covering the walls. English barns were normally without a basement and stood on level ground. The interior of the barns were characterized by a center driveway which acted as a threshing floor, similar to the breezeway of a crib barn. The double doors generally opened onto the center drive which divided the building into two separate areas, one for hay and grain storage and the other for livestock.
