Most of my DIY projects are borne of necessity, but this one was pure indulgence. I love the case study birdhouses at modernbirdhouses.com, so I took inspiration from the Neutra one. Made from cedar, it's naturally weather resistant. I used simple butt joinery of four equal sides with an open top and closed bottom. The roof is an Ikea cutting board, cut for an overlap and hinged in back. This allows for an annual cleaning of the nest.
