About 15 years ago, my father decided to create a Martin bird house. It wasn't a difficult project, and apparently it was fairly well built, for only now is it starting to die. But it's dying at a rapid pace...and I'm sure will be taken down and tossed in the fire pit soon.
Here is a portion of that bird house. The colors underneath the peeling paint have a nice antique feel to them. The fact that it looks like it's going to fall apart also helps add that feeling.
