The classic birdhouse, the name of this project, is called this because it is the basic style of birdhouses that you see most often. It is extremely easy to build and doesn't cost anything if you have an old fence board* laying around.
There are many styles and shapes of birdhouses, but the classic style has always survived over the years. This is a great class project for young students and scouts that are interested in woodworking. By building this project, they can get the feel for what woodworking is like, and when they are finished with the project, they have a birdhouse for their backyard.
You can build this birdhouse with a single 1" x 4" x 6' fence board (or other similar material). Using your miter saw or circular saw, cut the following lengths:
Before you begin assembling the pieces, take out two of the 7" x 4" pieces. On one of the pieces, cut a 45 degree angle on both sides of one end to form a point (see diagrams below). This forms the shape of the roof. Repeat this process on the other 7" x 4" piece. All of the parts should now be cut and ready for assembly.
