What is a Tiny House A-Frame
What is a Tiny House A-Frame
FRAMES have always fascinated me as a bit of nostalgic architecture, but also as an interesting snapshot of American optimism. They rose to popularity in a time when many were entering into the middle class and cars became common place.
The idea of the weekend getaway became a thing for the first time and people look to rural parts of the country to build a cabin in the woods. Enter a simple but practical design called the A-frame.
Today’s modern A-frame tiny houses are designed and built with full-time living in mind. Although many people still adore this architectural style as a cabin or vacation home, the shape has really taken off in the tiny house movement.
Now, not all A-frames are considered tiny houses. In fact, there are small A-frame houses and even quite large options. A-frame tiny houses usually fall between 100-400 sq. ft. Small tiny A-frame houses are typically between 400-1000 sq. ft. Both styles are popular for those who want to build their own dwelling and take on tiny house living.
Pros and Cons of Tiny House A-Frames
Pros and Cons of Tiny House A-FramesLike any architectural style, A-frame tiny houses come with a list of pros and cons. The biggest advantage of the style is that it is relatively easy to construct, which appeals to many who want to build their tiny A-frame on a small plot of land.
The simple design means you do away with side walls entirely, opting for a larger roof plane instead. What normally would be a wall system made up of studs, top/bottom plates, sills, and a complex roof truss structure becomes a single piece of lumber you only have to make two cuts on.
This monolithic roof isn’t without its downsides, though. The sloped roof creates less usable internal space because you can only stand up straight so close to the wall.
A-frame tiny houses tend to skew a bit bigger than most because you need a wider and taller house to have enough livable space within the sloped roofs. If an A-frame style is appealing to you, don’t get too caught up in thinking a tiny house “should” be so many square feet, build a house that works for you!

Design Tip:
A-frame houses have a special design and don’t fit to every environment. The steep roof pitch is likely going to be problematic in urban areas. In the countryside, however, there are often less code restrictions to follow, making it more likely to get a green light from the local authorities to proceed with the project.
With an A-frame tiny house kit, you’ll get precisely the right materials and pieces you’ll need. You won’t have to worry about the planning and troubleshooting, which can lead to expensive mistakes. Even expert tiny house builders make mistakes that can add up, so if it’s your first time, weigh out the cost of your time, planning, and an allotment for any mistakes before deciding that a kit is a more expensive route. In the end, you may save money by opting for one of these great A-frame tiny house kits.

Before you start building an A-frame house be sure to research city and county codes and make sure your room sizes will fit with at least 5 feet hight at outside wall or more for appraisal, if need.
A-Frame on a Foundation VS an A-Frame on a Trailer
So should you build your A-frame tiny house on a foundation or on a trailer? Well, it depends on your needs. The main reason to build any tiny house on a trailer is usually to get around building codes. The other advantage of a trailer is that you gain mobility. Should you decide to move someday, you can take your house with you.
If the building codes aren’t a concern for your area (and be sure to check out the codes thoroughly before you build), then you can certainly build an A-frame tiny house on a slab foundation. A benefit to building on a foundation is that you can make it wider,creating more floor space.
Since trailers have a maximum width allowed by the DOT, you’ll only be able to have an A-frame tiny house 8.5 feet wide, which doesn’t leave a lot of room inside with the steel sloping roof.
A-FRAME ON A FOUNDATION
Building an A-frame on a slab foundation allows you to size the A-frame cabin or tiny house to your preference. You can create it as wide as you like, which enables you to lower the roof’s angle. If you build on a foundation, take the time to research the different foundation options (pier, slab, crawlspace, or basement). A slab foundation is generally less expensive than building on a trailer, so that’s something you should also consider.
A-FRAME ON A TRAILER
If you choose to build your A-frame on a trailer, you’ll be beholden to the size of the trailer (8.5 ft. wide). That said, there are some significant advantages to building any tiny house on a trailer (which is why I built my own tiny home on a trailer). When you build on a trailer, you’ll build from the bottom up — sizing the flooring and the base first. This video walks through an A-frame tiny house build on a trailer.

A-FRAME EXPERT CONSTRUCTION TIPS
Because A-frames don’t use conventional framing, there is a lot less information about structural things like spans, member sizes, fasteners and so on. Make sure all parts of your design have been looked over by a structural engineer.
It is always smart to have 1 person in your team with a construction background to eliminate possible mistakes. Obviously all the special parts (plumbing, electrical system, HVAC etc.) should be done by a specialist.
Take your time and enlist help when it comes to raising the A’s and in the sheathing and roofing phases (for larger a-frames), you’re dealing with an extremely steep roof pitch with most of these and lugging and affixing huge plywood sheets from a ladder can get tiring, not to mention dangerous, in a hurry. Consider some good scaffolding, too.
Consider using a metal roof as it is fast, efficient, and lower maintenance than other choices. Also, if the A-frame will have electrical power, use mini-split heating/cooling units to save on space that would be required for duct-work.
Ready to build an A-frame tiny house? I’ve broken down the tools and guidelines here to help you plan your big build. An A-frame small house, cabin, or tiny home is a good way for first-time builders to learn as they go. The A-frame shape is a simple design, and if you opt to build from a kit, the process can be even easier.
Of course, there are plenty of pre-built options out there as well, but if you’re hoping to save money and DIY, this is a great option. A-frames also make nice vacation homes, satellite offices, studios, or guest rooms. Watch this video for more details on what it takes to build an A-frame tiny house.
How long does it take to build an A-frame? How much will your A-frame cost? It all depends on the simplicity of the design, your experience, and materials. A simple A-frame shed or camping space may take only a day or two and cost less than $5000. A more robust design could take weeks or months and cost thousands more.
Common Tools For Building An A-Frame
You can build an A-frame tiny home with a pretty basic set of tools, but you might want to invest in a few labor-saving ones. If you’re starting from scratch, plan on spending about $1,500 dollars for everything you’ll need.
While you can go middle of the road or buy some used tools for many of these, there are a few tools I’d buy brand new and consider paying a little extra for higher-end versions. The first one is an impact driver and drill set with four batteries — this is going to be a tool you use a ton and for this I’d budget between $300 to $400. You don’t want to cheap out or buy used, particularly when it comes to batteries.
I’d also splurge a little and purchase a basic 6-gallon compressor, with a brad nailer, a finish nailer and a framing nailer. While you can certainly use a hammer for this, you’ll move a lot faster and save a lot of energy if you have an air powered set of tools. You usually can get a compressor with a hose and 2 smaller nail guns for around $350 and a framing nailer (I’d consider used for this) for $100-$250.
The final thing I’d splurge on is a good level and maybe a laser level, too. Cheaping out on these things will only hurt you later, as making sure things are level and plumb is critical.
Estimated Usable Floor Space in an A-frame
How much space will you have in your A-frame tiny house? It’s always best to calculate the space you’ll need before you start to build. It’s also essential that you know the building codes in your area so you can get the proper permits and be sure the dimensions are up to code. With an A-frame, the useable floor space is the biggest question. Use the grid below to help you measure and plan.
| Size | Foot Print | Usable Sq/Ft |
|---|---|---|
| 8′ x 8′ | 64 sq/ft | 10 sq/ft |

A-Frame Interior Height Chart
How tall will your A-frame be? The size of the flooring dictates the pitch of the roof (determining your interior height). Use the chart below to help you calculate your ceiling height. Remember, if you want to include a loft, you’ll want a steeper pitch (or a bigger floorplan).
