Following the first pallet cabin I've made in august 2013, I've decided to build another one little bigger for teenagers. The simple way was to use new pallets with my personal design & sizes, but it's possible to use old wooden pallets instead of new ones if you have some available. I've used 19 pallets for this cabin. If somebody is interested or need some information, do not hesitate to contact me. Thanks for your comments.
