House Types
Many farmhouses are not examples of any recognized architectural styles and are in fact designed according to vernacular traditions based on cultural heritage or regional preferences. Often elements of popular styles are applied to basic house forms, so that the resulting buildings have multiple influences.
Some farmhouses have undergone change over time with the addition of wings to add space and functionality and architectural details popular of the era. Others have been changed by the removal of original or historic features such as decorative porches, cornices or windows, doors and shutters.
Continental Pennsylvania German HouseThe "Continental plan" consists of an asymmetrical layout with a door leading to a long, narrow kitchen anchored by a large hearth. Opposite the kitchen lay a stove room and behind it a kammer or bedroom. Though its provenance is complex, this type is associated most with Pennsylvania Germans. The exterior diagnostic features include an asymmetrical facade, off-center roof-ridge chimney, and roof "kick". Variations on the three-room plan persisted through the 19th and into the 20th century in heavily Pennsylvania German regions. | Immel house, Jackson Township, Lebanon County, 1759. |
Five-Bay HouseThe Five-Bay House is a common vernacular form with a central front door and symmetrical window placement. Often featuring a center hall, it is similar to the floorplan of the I-house, but on a larger scale. Five Bay Houses are often embellished with decorative stylistic elements such as a Gothic Revival style front facing gable, bracketed cornice or front porch with turned posts. | ve-Bay House, Greenwood Township, Columbia County |
Four Over Four House Or PA German Double- Door FarmhouseThe Four Over Four House (also called the Pennsylvania German Double Door Farmhouse) is a vernacular house form found in areas settled by the Pennsylvania Dutch featuring a 4-bay front façade, two (or one) central side by side front doors and a side-gabled roof. These four bay houses do not have a center hall, each front door opens directly into a room. The form and floor plan show the influence of PA's sizable German (PA Dutch) population. Found only in PA and in surrounding states, the form is uniquely American - a blend of traditional German floor plans and the popular symmetrical Georgian/Federal style. The Four Over Four name refers to the four bays over four bay front façade, since the houses are usually two stories tall and two rooms deep. | Four Over Four house, Greenwood Township, Columbia County |
Foursquare HouseThe Foursquare House was a very popular form used throughout the country in the early 20th century.

Usually three to five bays wide, one room deep and two stories in height, I-houses have side-gabled roofs. They often feature one or two-story rear additions. While common in PA and the Middle Atlantic region, the I House name comes from its prevalence in the midwestern "I" states Iowa, Indiana and Illinois. | I-house, Cecil Township, Washington County |
