A-frame houses are made by leaning 2 tall walls against each other – so they look like an A.
These tall walls act as walls and roofs at the same time, making construction extremely simple. When tall enough, there is space for a second floor, usually used for bedroom lofts.
The simple structure makes them easy to build, even for self builders. as it lacks the typical connections between floors-walls and walls-roofs which require more building know-how.
Although a little space can get lost under the “leaning” walls, these are usually used well for storage and installations.
Why are A-frame buildings smart?
- simple: one single panel does the job of walls and roofs
- the panels lean against each other, making it a structurally sound system that resists well to winds etc.
- easy to self build, especially with SIPS or other sandwich panels
- less volume to heat/cool
What are the limitations of A-frames?
- In smaller sizes, the walls may feel as if they’re closing in on you
- Windows and doors are often limited to the front and back – and need some triangular shapes. It is possible to put them in the leaning sides… but then you loose some of the simplicity.
- The leaning sides must be positioned well depending on the climate. If positioned east or west, they will catch a lot of sun.
- Sometimes perceived as a “cheap” solution and visually less imposing than a “normal” building with the same m2
