The  Flurküchenhaus (corridor-kitchen house) is the iconic Germanic house of early European settlers in Pennsylvania. Characteristics of these structures originally included a three or four-room floorplan, a front door that opens into a corridor kitchen, and a living room / dining room heated by a stove.
The Flurküchenhaüser on this page are a sample of Germanic vernacular houses that survive in Lancaster, in both the city and county. They are among the oldest houses in this region. They are remarkable survivors.

  Lancaster County, and many Pennsylvania counties, have numerous other historic Flurküchenhaüser. The photos here on this page represent only a sample of those landmark vernacular dwellings.
These structures are also found in the Pennsylvania German diaspora: in Maryland, Virginia, North Carolina, etc.
