Repurposed old wood can be transformed into a birdhouse by nailing together four small pieces of wood to create a house-like structure and affixing metal latches on the front for a rustic look. Old wood can be stained to create a darker or lighter appearance.
Individuals can customize birdhouses constructed from old wood by painting the wood bright colors and offsetting the paint with rustic knobs or painted mock doors on the front of the structure. Old wood should be clean and free of nails or metal screws before painting or staining the wood. Damaged sections of the wood should also be cut to avoid fraying or splitting while building the birdhouse.
