Unfortunately it's not in English, however the photos of the different log-cabins and bushcraft shelters are interesting to look at.

Thank you to the boys and girls of Ms. Martin's class who were researching log cabins and suggested this link to me. I hope you have fun learning about log cabins and perhaps one day building your own!
If you do build one please send me a picture of it as I would love to see it. You can get in touch with me here.
