 The term "Halle" ("hall") refers to the large open threshing area or "Diele" (also "Deele" or "Deel") formed by two rows of posts.The prefix "Niederdeutsch" ("Low German") refers to the region in which they were mainly found.Because almost all timber-framed and hall-type farmhouses were divided into so-called "Fache" (bays), the prefix "Fach" appears superfluous.
