Easy Wren Bird House Plans: 1 Minute to Build a Cozy Home for Wrens

Building a wren bird house can be a rewarding project for both beginner woodworkers and those passionate about attracting charming backyard birds. Wren bird houses are compact, simple, and do not require elaborate tools or expensive materials. An easy wren bird house plan often consists of a small rectangular or square box, a simple roof, and a tiny entrance hole—about 1 1/8 inches in diameter—to keep out larger, more aggressive birds.

To start, choose untreated wood (like cedar or pine) and cut your pieces: one front, back, floor, roof, and two sides. Drill the entrance hole in the front panel, assemble the box using exterior screws or nails (avoiding glue, as fumes can be harmful), and make sure to provide drainage holes in the floor and ventilation slots near the top. Hinge the roof or use screws so it can open for seasonal cleaning. Mount your bird house 4-10 feet above the ground, tucked away from strong sun and prevailing winds.

As a designer, I always recommend considering both functional and aesthetic elements. Integrate the birdhouse into your overall backyard design—choose finishes and placement that complement your landscape, or even coordinate with outdoor furniture textures and palettes. For a seamless finish, you can bring your design to life visually with a DIY room decor visualization tool, which helps plan and preview outdoor accessory placements for a cohesive appearance.

Tips 1:

When installing your wren house, avoid painting the inside as chemicals can deter birds. Consider roughening the interior with sandpaper beneath the entrance hole to help fledglings grip as they leave the nest.
