This birdhouse is one I call The Meter House. This house uses side cuts and regular 1X lumber. I used old tin roofing for the roof. There is a large gas meter kind of randomly screwed to the side, because I really liked how it looked.
The opposite side has some ventilation holes covered with screening and a ceramic outlet cover. The perch is ceramic as well, with a silver toned beauty ring and a piece of rusted metal roofing.
The house is asymmetrical in design, but I figure the birds won't mind too much. Maybe they'll have creative offspring.
