A-Frame Cabin Guide: 5 Tips for Building an A-Frame

An A-frame cabin is a building with a tall, triangular roof that resembles the capital letter "A." Typically, an A-frame is a two-story or three-story structure with a wide first-floor living area, a smaller second story above the living room, and a tiny top floor that serves as a sleeping loft. The front and back of the cabin generally have large windows that let in natural light. The energy-efficient design of A-frame cabins is perfect for cooler climates where there’s little need for air conditioning, which makes off-grid living possible.

Popular in wooded regions like Quebec, Oregon, northern Maine, and New York's Catskills, A-frames practically define the cozy cabin-in-the-woods archetype. Some A-frames are spacious with a wide footprint, while others are small enough to qualify as tiny houses. Many ski chalets in snowy areas are A-frame log cabins, and A-frame vacation cabin rentals are perfect for outdoor enthusiasts.

If you're building your own A-frame as a DIY construction project, you have three options.

1. 1. Build a cabin from A-frame blueprints. You can purchase a set of A-frame cabin plans from an architect or draftsman (or draft your own building plans) and buy all the raw materials—wood, fasteners, roofing shingles, etc. This allows you total control over the building process.
2. 2. Purchase a DIY A-frame cabin kit. An A-frame house kit contains both house plans and all the physical materials you will need for your DIY construction process. You'll still have to provide your own tools.
3. 3. Buy a prefabricated A-frame. If building an A-frame cabin with your own hands is not realistic, you can also purchase a prefab A-frame cabin from a builder. Tiny A-frame cabins can be loaded onto flatbeds and delivered directly to your property. You will still need to provide the building foundation, and the total cost may be higher than if you were to build every component yourself, but the process is far faster.

Whether you're building your A-frame cabin from scratch or purchasing a prefab unit, you'll want to plan carefully. Consider these six tips for designing and constructing an A-frame home.

1. 1. Situate the cabin in the right area on your property. Although A-frame cabin design is remarkably simple, your cabin still needs a sturdy foundation in well-compacted soil.
2. 2. Decide how the cabin will function. Will your A-frame cabin be a vacation getaway or a primary residence? Will it be investment real estate that you list as a cabin rental? The floor plan of a vacation home or rental property may be different from that of a primary home. A vacation rental might prioritize a big living room, while a primary home might have more individual bedrooms.
3. 3. Consider elevating the cabin. Like any small house, an A-frame can be short on indoor storage. By raising the home off its foundations, you can create storage space between the ground and your lower floor joists. If you encase the entire foundation in concrete, you can make this storage space waterproof.
4. 4. Add skylights. For more natural light, consider adding skylights to your A-frame. Skylights can make the home feel larger. Many A-frame house plans and cabin kits include skylights as part of their core design.
5. 5. Blend indoor and outdoor spaces. With their extra-large windows and wood frames, A-frame cabins allow you to feel close to nature. Consider bracketing your A-frame home with wide decks on either side of the building. Or, if one end of the building is at ground level, consider adding landscape features like a fire pit or a hot tub to extend the living space beyond the walls of the building itself.
