Durable knockdown flat sheet metal component birdhouse having slidable flanged edge assembly connections and flat wood panel interior liners. The assembly connections include U-shaped folded 180 DEG flanges extending in the plane of sheet metal panels slidably engaging mating 90 DEG flanges on adjacent panels to provide an integrated self-supporting box construction free of required supplemental fastening means. A plurality of such birdhouses mounted on a horizontal rod serve as equivalent to a multiple compartment "Martin" type birdhouse.
