My bigger, badder, 19 Pallet Teenager Cabin Hideaway:
The simplest way for me to plan and build this project was to use new pallets made to my specifications. However, it is still possible to build this using recycled pallets, too. I used 19 pallets to build this cabin. If somebody is interested or needs more information, feel free to contact me. Thanks for your comments.
