Where to start? There are so many lovely, unique and unexpected design features. The architect must have had fun with this project. It carries the eye from window to door, to watermill, to hay loft, - and there's the arched doorways, the timbered and stucco side-house. There's even a small stream.With a 1.25" opening, removable back wall, drainage, ventilation and an unpainted interior, there's no mistaking that this is a fully functional birdhouse.
