Remember to pick up plywood brackets for mounting support and make sure you have basic tools like a level and measuring tape.
If you're working alone, arrange for a helper during installation.
Cut and Join Pieces
Building your owl box begins with five precise cuts that form the basic structure. Using your saw, cut the cypress board or plywood to create a 15-22 inch front piece, 27.5-32 inch back panel, and an 8×8 inch floor. Cut two side panels between 16-32 inches long to complete the main structure.
Next, drill a 3-inch diameter entrance hole in the front piece, adding kerf cuts beneath it for better grip. Join the pieces using wood glue and nails, ensuring even spacing of screws for stability.
Add corner studs for extra support, and secure the floor with additional screws. Don't forget to create a small landing ledge below the entrance hole – it's essential for your future owl residents. When positioning your completed box, aim for an easterly direction to maximize the chances of attracting owls to your structure.
Seal and Finish Box
Once the basic structure is assembled, proper sealing and finishing transforms your owl box into a weather-resistant sanctuary.
Apply a generous bead of all-weather sealant along both sides of every vertical joint, keeping the edges smooth. The pressure-treated plywood ensures maximum durability against harsh weather conditions. Cover the hinged roof with thick roofing felt, securing it with galvanized nails into the battens only, and fold under the edges for complete protection.
- Carve essential kerf cuts below the entrance hole to help owlets grip and guarantee proper ventilation.
- Add untreated wood chips inside to create a cozy nesting environment.
- File down any protruding screws or sharp edges that could harm your feathered residents.
- Apply a coat of light-colored exterior varnish to the outside only, leaving the interior natural and safe.
Remember to check that all joints are properly sealed, as barn owl debris is highly absorbent.
