If you are going to build using pallets only use ones marked HT (heat treated) and reject any that smell or are stained. That said… you’ll find 4 pallet projects here including a $5 greenhouse.
The Pallet Pavilion
The pavilion was built as a temporary meeting place for media and athletes after the World Ski Championships in Oberstdorf, Germany.
