One of my original Cape Cod bird houses was mounted in our yard for the last few years (Picture on the left)  Unfortunately instead of attracting a bird family it attracted wasps and became filled with a wasp nest.  I had to destroy it because there was no getting the nest out once I had killed the wasps.

Decided on a new design.  I call it a Hobbit House since it is roughly based on a Hobbit design (big round door,  round windows and curved roof)  I have added the design feature suggested by Blaine to avoid wasp infestation in the future.

100% Cedar and made with proper outdoor glue.
