Apartment Size: 4.5″L x 5″W x 5.25″H (11.4cm x 12.7cm x 13.3cm)

Step 2. Prepare the Side Doors for the Purple Martin Nesting Box.

Drill three entrance holes in each piece using either a spade bit or forsnter drill bit. An entrance hole size between 2.25″ and 2.5″ (5.7cm – 6.4 cm) is the optimum diameter for purple martins. 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.

FYI: If you plan on adding hinges to these doors, you will need to make the width slightly smaller based on the thickness and placement of your hinges.

Step 3. Prepare the floor of the Bird House.

Cut three pieces of wood as shown below.

Step 9. Assemble Your Wooden Purple Martin Birdhouse.

Now, use a combination of glue and screws to attach the sides, floors, roof, and bird perches together as shown in the image above. A waterproof wood glue is recommended to help extend the life of the birdhouse. 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 holes for screws in bird box.

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.

Regular vs trim (finish) screws.

If you want to make your bird house easy to clean and service use a combination of hinges and door latches to hold the side doors (labeled “B”) in place. While not as easy to service, the side doors can also be held in place using screws. Learn more about access doors and cleaning bird houses.

Step 10. 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.

Step 11. 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. Your new birdhouse should provide you excitement for many seasons to come.
