Step 1. Prepare the “Long” Side of the Bird House.

Cut one piece of wood as shown below (labeled “A”) using a miter saw, table saw, band saw, or some other saw. Personally, I am using cedar wood.

Step 2. Prepare the “Front” and “Back” of the Bird House.

Cut two pieces of wood as shown below (labeled “B”). In one piece drill an entrance hole using either a spade bit or Forsnter drill bit. A 1.5″ (4 cm) entrance hole is the optimum diameter for bluebirds and tree swallows. However, chickadees, nuthatches, warblers, woodpeckers, and wrens will also gladly make this their home. See Bird House Hole Size if you want to attract a specific bird. Optionally add a Birdhouse Perch.

Step 5. Consider Adding a Cleanout Door to Your Birdhouse.

If you use screws to assemble your bird house, it can easily be cleaned out by removing a few screws. See Cleanout Door Ideas for other ways to add an access door for cleaning.

Step 6. Assemble Your DIY Birdhouse.

Use screws to attach the front, back, and sides together. Drill pilot holes to help prevent the wood from splitting. Ideally, the pilot holes should be at least as large as the screw’s minor diameter.

Pre-drill screw holes in bird house.

Personally, I recommend using stainless steel trim screws as shown below. The smaller screw head is less obvious and helps prevent the wood from splitting. If you pre-drill the holes, these screws will countersink themselves nicely because the head is not much larger than the pilot hole.

Trim vs regular trim screws.

Step 7. Optionally paint or finish your birdhouse.

In our case, we applied a linseed-oil. This finish helps accentuate the grain and helps make the wood more resistant to damage.

Apply linseed oil to protect bird house.

Step 8. Hang or mount your birdhouse.

Mount your birdhouse and see which bird will call your habitat home. See How to Hang a Birdhouse for the recommended mounting height for various birds.
