Barn-style houses are known for their simple, rustic exteriors, which are almost always clad in wood plank siding. Most commonly these planks are installed vertically, which helps keep rain water from seeping into the house between the slats. Some barns use a board-and-batten wood siding, which has a narrow strip of wood that covers the joints between each plank. The other most popular type of barn-style siding is shiplap, which has wooden grooves that allow the boards to be installed tightly together with flush joints, with no need for covering. 

Primarily, there are two different types of frames barn-style houses are constructed with: timber, and post-and beam, which both feature exposed wood trim and open, customizable floor plans. A timber framed barn is made using large, flat lengths of wood, and large, sturdy wooden beams that allows for expansive, open interior spaces. Thanks to modern construction methods, a timber-framed barn-style house is extremely stable without needing a ton of joists and braces, which gives these homes a cavernous, lofty feel.

In post-and-beam barn-style houses, heavy timbers are used instead of flat-planed lumber, held together using wooden joiners, and do not have any load-bearing walls. Post-and-beam is the traditional style of barn framing, and has been used for hundreds of years; this framework is extremely durable and sturdy, which is why it’s not uncommon for barns to last for centuries. 

The most common style of roof found on barn-style houses is the gambrel roof, which is a symmetrical two-sided roof with two distinct slopes; the upper section being at a shallower pitch than the lower one. These roofs are best for two-story barns; in the classic gambrel style most of us associate with barns, the upper section of the roof covered a hay loft, and its flatter slope allowed for more space (not to mention enough room to stand), and still offered excellent drainage. 

Some barn-style houses are built with simple gable roofs, which is two-sided, symmetrical, and triangular. A hip-roofed barn-style house has slopes on all four sides, all equal in length, that meet at the top to form a long, straight ridge. Smaller barn-style houses may have a shed roof, which has a straight, flat pitch, with its front side slightly higher than the back to allow for drainage. 

A barn-style house can be built with a small dome, known as a cupola, atop their roofs. Cupolas were originally built to let heat escape from the top of the barn; in today’s era of climate-controlled homes, these cupolas are simply decorative. 

Traditionally, barns were built without windows. In today’s barn-style houses, though, windows can range from small and sparse, to utterly massive; in some modern designs, gigantic windows can take up most, if not all, of an exterior wall. Mostly, barn-style houses have a plentiful amount of large windows that flood the spacious, open interior with light.

Even though barn-style houses aren’t built to house livestock, they still have the large, sliding doors used for barns on working farms. These heavy doors are hung from sturdy metal rails; in some barn-style homes, these doors are used as a way to partition indoor space, allowing rooms to transform from fully open-concept, to walled off and private. 

The most common features of barn-style houses are:

• Timber frame
• Wood plank siding
• Gambrel roof
• Expansive, open interior
• Second-floor loft
• Large windows
• High ceilings
• Exposed timber beams
