Step 1

The first step in building a log cabin is to create the foundations. You should dig down until you reach firm and stable soil, as well as deep enough to provide enough support for the structure. For exact measurements, you can ask a structural engineer for advice.

Lay several rocks within the foundation that you’ve dug up to allow for water drainage and to keep your log cabin raised. The number of rocks you’ll need will depend on the size of the cabin you’re building.

Step 2

Next, you’ll want to add a concrete mix to your foundation to ensure it stays sturdy and level. If it is not level, this can have a big impact on the rest of the cabin build.

Start by laying a wooden framework around the perimeter of the foundation to keep the concrete in and then pour concrete into the foundations.

Step 3

Next, you will need to place concrete pads in each of the four corners of the foundation. This will essentially lift your cabin away from the floor and will prevent the construction from becoming damaged by water.

Step 4

Next, you will need to lay your sub-floor. If you're building a small cabin, lay pad stones in the centre of the foundation, but for larger projects you should consider concrete piers or complete slabs to evenly support the weight of the build.

Step 5

Next, you will need to install the framework for the walls. You will usually need two people to do this as it requires some lifting and steadying. You will need to secure the framework as you go along. Although it is not always necessary, the frame will give you something to work off when installing the logs themselves.

Step 6

Next, you will need to decide on a notch type. Your logs can be notched in several ways to help them fit together. You will need to cut all of the logs at the edges to create the appropriate notches that will allow your logs to fit together perfectly in the corners.

Step 7

Once your logs are prepared, you can then lay your sill logs. The best logs for the sills are those that are the thickest, longest, and straightest. Begin by laying these four logs around the frame at the bottom. It’s best to work with the thickest logs at the bottom, moving up to thinner logs at the top.

Your sill logs will need to be secured and drilled into the frame to keep them in their correct position. Ensure that the logs are notched together appropriately at each corner.

Step 8

Once your base logs are in position, you can now work on creating the cabin floor. You will need to lay floor joists roughly 14 inches apart. Create notches in the sill logs so that the floor joists can slot in place. Ensure the notches are the same width as the floor joists so that you get a snug fit when laying them.

Once your joists have been laid, add your top layer of floor planks on top of the joists. These should be drilled into the joists to keep them in position.

Step 9

When you’ve finished fitting your cabin floor, you can then construct the rest of the walls. Each log should be slotted into place using rebar pins or with through-bolts and notched to the joining log at each corner. Continue to build up all four walls using this technique, and be sure to leave gaps for doors and windows as necessary.

Step 10

Once the walls are completed, you can then move on to building the roof. You should start by building the outer frame for the roof. Measure and cut your rafters to size according to the size of the roof that you’re building. You should also take into account the pitch height when doing this.

Create a notch at the end of each rafter to help it sit in place correctly.

Step 11

Once the frame is built and installed, you should then install roofing boards. These boards can be drilled into the rafters to secure them in place. You can then install the finish to your roof.

You can choose several finishes, including thatched, wood shingles, metal sheeting, or roofing felt. The design you choose will be based upon your personal preference and should be installed according to the manufacturer’s instructions.

Step 12

Once construction is complete, you can now fit your windows and doors. You should begin by constructing and installing window and door frames to each of the openings. Your windows and doors can then be installed onto the frames to ensure they’re secure and safe.

Door and window frames can be constructed simply by drilling pieces of timber around the gap where the window or door will go. Doors will not need a piece of timber at the bottom.

Step 13

This concludes the construction part of the log cabin. You will now need to treat the wood. Clean the logs using a mild detergent and a soft-bristled brush to remove any dirt or debris that may have accumulated during the construction stage.

You will then need to leave your cabin for at least two days to completely dry and set, depending on the local weather conditions.

Step 14

After the two days is up, you can then stain your log cabin. This will help it to retain its colour and will protect it from harsh UV rays.

Step 15

The final step in building your log cabin is to seal it. It is best to use sealing caulk on all of the joints, as well as filling in any cracks that are larger than 2cm. This will prevent air and moisture from infiltrating the cabin.
