Remember our post about paying to sleep in an old drain pipe? Well now next time you go to London, you can sleep in an old shipping container. Travelodge is getting their recycle on with this hotel made completely of old shipping containers. It may sound like a gimmick but besides the fact that they are reusing manufactured materials, using this method allowed them to build 25% faster, using less energy. The steel buildings are strong and apparently you'd never know you were sleeping in a shipping box. Check out SmartPlanet for the whole story and more pictures of this cool sustainable structure.
