Watanabe design is an anti-modern architecture. From public facility to a private residence, it is not possible to explain the origin of the form of the structure, function or purpose of the building. Watanabe intention is to design using the light as a point, in addition, he is reproducing the original state of architecture before the style of architecture was established, or before becoming a classic.
