Rachel Armstrong argues that architecture that repair itself. Some of the building has the unique item before it was build. such as the blueprints, the workers and so on. Sometimes the building transform from small until big architecture. This sustainable, but in this century it can set with chemical reaction, and this is the way in wich living materials. She prefers to use metabolic materials for the practice of architecture and has a dream to collaborating her design with international scientists, due to the reason that It could move around the environment. She had made the research about some material, in a long time ago, until she found the unique material that called bottom-up material. In addition, if some people look even closer, the material could show the limestone, the little shells and little skeletons that are piled
upon each other. She makes the conclusion that the architects are never happy with just one block of an interesting material.
