This is the Green Wood House, a simple paper model in three sheets of paper.
I don´t built this model, so I don`t know the exact scale, but I think it is something about 1/64 scale (the size of Hot Wheels miniatures).
The model is in PDF format and you can download it easily, directly from Google Docs.
