My neighbor has a bird house, I wondered if that would work. It is in disrepair so I discarded that idea.
I had a photo of a houseboat with a lot of geese. No, that won't do.
How about the lake house I visited this past Spring? No, not that one.
So I decided on a house that really isn't there. You can see the garage entrance and the railing on the roof with an entrance on the far side. The house is completely underground. The people were very energy aware and wanted to insulate the house with the dirt. No windows in this house so it is dark all the time. Definitely something different for the header contest.
