Architecture is not just about complexity and beauty. When you add another important aspect which is environment, it enters another dimension.
Here is an example of an outstanding architecture, a new concept store by Starbucks made of shipping containers.
People might see their decision of using containers as just being à la mode, (the materials are used by a number of architects and designers nowadays), but I personally think that this is a very good initiative that should be encouraged!
Big, beautiful AND environmental friendly!
