Travelodge, a British hotel chain, has built the very first recyclable hotel. The rooms are pre-built in china (complete with bathrooms)and are basically container-like crates that are stacked and bolted together.
The building not only cheaper adn faster to erect than traditional buildings, it is also easy to dissasemble and then reassemble elsewhere as needed.
