All of my birdhouses are personally hand-built with 1/2" signboard (Plywood). My roofs and bases are 3/4" Clear Pine. They are glued and nailed. I wrap the houses with vinyl and apply a clear laminate. This birdhouse is wrapped on 3 sides, for mounting on a tree or fence. (the back is exterior MDF unfinished) You have the option to have this as a hanging birdhouse, wrapped on all 4 sides. It can also be mounted on a pole. Please specify when ordering which you prefer. Four sided wrapped birdhouses cost $75.00. If you wish to order the 4 sided birdhouse, message us and we will send you the link. Great for indoor or outdoor.
