Space is always given, but it can be modified with signs, it can be reconstructed. In this space, in this colourful chaos, family homes and representative buildings, insignificant and significant buildings are lined up as tiny signs. The signs are determined by the era, the requirement of the commissioner, the law, the talent of artist. The seal of these react to space and time, living creatures and human beings and are imprints of a given era in history and the history of architecture.
