The A-frame house has returned. Inspired by the tiny house movement, the A-frame home is undergoing a renaissance. With their unmistakable shape, new A-frame home designs are changing how people perceive the living spaces.

According to the National Association of Home Builders (NAHB), “Builders continue to start homes as the demand for new construction remains solid in a market lacking inventory of previously owned homes,” said NAHB Chairman Jerry Konter.

As home building continues its ascent, A-frame homes are also in high demand. If you’re new to architectural design, an A-frame house is named after its shape – the letter “A.” 

What Is An A-frame House?

The A-Frame HouseView in gallery

An A-frame house is a triangular shaped structure that looks like the letter “A.” The structure provides covered shelter and features a sloped roof. The homes are located in the wilderness, where they’re allowed to be built.  A-frame homes are smaller than traditional residential homes. 

The first A-frame home in the US was built in 1934. After World War II, A-frame homes began to appear in the Great Outdoors. Many people think A-frame homes were a 20th-century invention, but that isn’t true. Early civilizations throughout Asia, for example, lived in thatched huts shaped like the letter A. 

Beginning in the 70s, A-frame homes cooled. However, thanks to the tiny home movement, A-frame homes are in demand more than ever before.
