100 Wild Huts is Kevin Langan's ongoing project to: "build 100 small survival shelters on any piece of ground that harbours enough natural resources for the build. I intend to sleep rough in each shelter for one night and blog about the experiences." He is down to five so far and already the range of designs is impressive. When he is done the result with be catalogue for primitivist-survivalists looking for inspiration. Great stuff. Langan is a long distance walker with a 132km Highland walk guide book to his name.
