This simple kit comes pre-cut and drilled, with dowel pins for easy assembly. The roof of the Wood Birdhouse DIY Kit is hinged (hinges attached) for easy cleaning. All the kit needs is white glue for the joins — and potentially paint, which makes a great project with kids. It all ships in a cardboard box. The finished kit simulates exactly the type of hole in a tree that attracts chickadees to nest. 15cm x 15cm x 36cm (6" x 6" x 14").
