Compared to making a city solely out of one building, it is rather important for people to understand what roles a building can play in a city; especially within urban condition. How a building could actually react and respond to certain human perceptions and functions as an element of a city has become a significant issue. From place to place, the city mutates in several different phases, such as usage, terrain, orientation and material.
