00:00Hello everyone and welcome back to my channel. In this video, I'm going to show you how to frame
00:05an A-frame cabin. I'll walk you through building the foundation, adding the beams and raising the
00:11A-frames. The cabin will be 20 feet by 29 feet. If you'd like the plans for this cabin, the
00:19link
00:19is in the description below. It has two bedrooms, a small dining area, one bathroom, kitchen,
00:28and lounge. The plans come with full instructions on how to build everything,
00:34from the foundation, framing, and roofing to the interior work and venting, all included.
00:39So let's get into the video. We're going to start with the foundation,
00:43and here are the tools and materials you'll need. 15 sonotubes,
00:49at least 90 feet of half-inch rebar, one-inch gravel, and
00:58concrete, and 15 6-inch post anchors.
01:04We'll begin by marking and laying out the pier locations accurately on the site using strings
01:10and stakes. Then we shall add the diagonals to make sure the foundation is perfectly equal.
01:16Finish with spacing strings. Once that's done, mark the whole locations at every string intersection
01:23with anything circular like a bucket or even a piece of sonotube. Something like this.
01:31After marking, remove the strings.
01:35And then dig the holes.
01:37Each hole is going to be at least 24 inches wide with a depth of 36 inches.
01:44At each hole, we'll add 6 inches of gravel, install the rebar, place the sonotube.
01:54We can use 18 inches diameter sonotubes. 12 is fine, but 18 would be the best for this size of
02:01structure.
02:02Fill up the sides and add support using stakes.
02:06Pour in the concrete.
02:10Finally, before the concrete dries, we'll set the post anchors.
02:14Make sure that all post anchors are perfectly aligned so that the cabin sits square and straight.
02:20This prevents stress to the beams.
02:22Allow it to cure for 48 to 72 hours before applying any load.
02:33The beams are 29 feet long.
02:37Each beam is made by laminating 3 2 by 10 together using wood glue and nails.
02:47Use half-inch bolts and 3-inch screws to secure the beams to the post anchors on each pier.
02:54All rafters are made with 2 by 8 timber.
02:58For this plan, we use 4 A-frame rafter designs.
03:01Each rafter is 20 feet long on all sides, forming an equilateral triangle.
03:07Frame A is made with 4 rafters.
03:10Here is where it sits.
03:12We need 6 of these.
03:15The bottom uses double rafters for added strength.
03:19These are joined using half-inch bolts and 3-inch nails.
03:23Don't forget to leave a 2-inch gap here to allow room for blocking.
03:27The top is joined using wood glue and nails.
03:31Frame C is made with 5 rafters.
03:34Here is where it sits.
03:36We need 6 of these as well.
03:40The middle rafter creates the upper room, while the bottom rafters are also doubled.
03:45The top is joined using wood glue and nails.
03:49Frame B is made with 8 rafters.
03:52This is the one that holds the door.
03:55Here is where it sits.
03:56We only need one of these.
04:00The side rafters are doubled to create a 4-inch wall, and the bottom rafters are also doubled.
04:06The top is joined using wood glue and nails.
04:09We also double the header for the door.
04:12Frame D is made with 7 rafters.
04:16Here is where it sits.
04:18We only need one of these.
04:21The side rafters are doubled to create 4-inch walls, since this frame forms the back wall,
04:27and the bottom rafters are doubled as well.
04:29We shall use 2x4 timber to build the studs.
04:37Raising the first A-frame correctly is very important because it guides the alignment of all the other frames.
04:43With the help of two friends, raise the first A-frame and secure it with temporary supports.
04:53Use a spirit level to make sure the frame is standing perfectly upright.
04:57Next, attach it to the beam using hurricane ties on both ends.
05:03It's important to keep the temporary supports in place until the third frame is raised.
05:09Use a string line to ensure that all the A-frames are perfectly aligned.
05:13Secure the string tightly along the length of the structure, with one end held at the peak of the first
05:19A-frame and the other end secured to a wooden stake.
05:22Check each frame against the string as you install it.
05:25This helps maintain a straight build, ensures even load distribution, and prevents alignment issues when installing the roof and wall
05:33framing.
05:35Now add the second frame and space it using a 2-foot, 8x2 timber piece.
05:45At the bottom, add another 2-foot, 8x2 timber piece for blocking.
05:51Secure the frame to the beams with hurricane ties on both ends.
05:56Continue raising and securing the remaining frames in the same way.
06:24Finally, add the top blocking using joist hungers.
06:28The spacing is 24 inches as well.
06:38After the framing, you can now decide where to place the skylight windows.
06:43The rest of the information regarding the Sun Valley A-frame cabin is included in the plan which is in
06:48the description box.
06:50An A-frame house is a good house because its triangular shape is naturally strong and stable.
06:56The design allows weight from the roof to travel directly down into the foundation, reducing stress on the structure.
07:02This makes A-frame houses highly resistant to strong winds, heavy rain, and harsh weather, while the steep roof helps
07:10water and snow slide off easily, preventing leaks and long-term damage.
07:15A-frames are also simple and cost-effective to build.
07:19They use fewer materials than conventional houses and don't require complex roof systems, which reduces construction time and labor costs.
07:27This simplicity makes them ideal for DIY builders, cabins, tiny homes, and off-grid projects.
07:34Their compact form also improves energy efficiency, helping retain heat in cooler climates and stay comfortable when properly insulated.
07:43The iconic shape blends beautifully with nature and stands out as both modern and timeless, making A-frame homes perfect
07:50for personal retreats, rental cabins, or creative builds.
07:55All right, that's it for today's video.
07:57Thanks a lot for watching.
07:59Wish you luck with your project.
08:01Take care.
