A-Frame Cabin Cost

A-frame cabins typically cost between $125 and $175 per square foot to build. Since cabins are usually smaller than traditional houses, cabin building costs per square foot might be higher than the cost to build a house. Still, you can expect your costs to be comparable, if not the same, to building an A-frame house.

A-Frame House Kits Cost

A-frame house kits usually run from $60 to $140 per square foot but costs can vary. Some kits might run upwards of $600 per square foot.

An important thing to note is that the starting prices of A-frame kits are typically not reflective of the final price. Adding fixtures, cabinets, windows and doors will all cost extra. Things like plumbing or insulation cost extra, as does shipping and sometimes even insulation.

DIY A-Frame vs. Hiring a Professional

Whether you opt for a kit, a custom build or trying to take everything on yourself, at some point you will likely need a professional’s help when building an A-frame. This is especially true if your design has a heavy metal roof or shell. You’ll need special equipment and a special license to get everything into place.

While kits might seem more affordable, those prices often don’t include things like plumbing or flooring. In some instances, a custom A-frame could actually be more cost-effective. Find a custom home builder to get a quote and weigh out all your options.


What is an A-frame?

A-frames are houses that are notable for their steep roofs, which usually extend all the way to the ground. Their design tends to be more naturally energy-efficient than a traditional house. While often designed as cabins or getaway houses, A-frames have become increasingly popular as full-time homes.

What does an A-frame cabin cost to build?

Building an A-frame cabin usually costs around $150 per square foot, though you could pay as little as $100 per square foot or as much as $300 per square foot or more. The larger your cabin, the less your square footage costs, due to economies of scale.

How much does it cost to build a modern A-frame house?

A modern, 1,000-square-foot A-frame house will likely cost at least $100,000 to $200,000. Depending on where you live, accessing modern building materials could raise or lower the price. Certain custom modern items (such as windows or a roof) cost more the further you need them shipped.

How long does it take to build an A-frame?

A-frames take between four to eight months to build, on average. Highly custom designs or tricky building locations will take longer.
