Most modern cities planed under the influence of modernism. These cities in the process have experienced in the general population into the city, living in inadequate space, and then the city began the process of expansion etc…. Taipei’s urban development started slowly, but still in the concept of modernism’s urban planning. However, the same concept in the planning under Taipei city and the Western cities are having a different appearance. Taipei looks like a chaotic city, and much different from CIAM’s concept-functions. Different functions will also be in the same building, to help residential and commercial activities close mixed use. Because high oil price in recently years, the Western city of residential and commercial areas of over-separation, caused by motor vehicle must be generated to solve the traffic problem of consuming too much oil, they began to reflect on the life of such functions, but rather as Taipei this mixed residential and commercial space has become another kind of accident is more suitable for people living in urban space.
Taipei has a convenient feature of the city, a mixture of residential and shops in Taiwan as a result of the early house type which first floor planned for shops from a way of life extension. With metropolis’s steps, the way of life does not change so much that first floor still planned for shops. Commercial activities in order to attract the consumers, first using signs, then with the enhancement of consumer brands for commercial space by the atmosphere created by the application of interior design in addition to space, but also extends the surface of the building. Therefore, Taipei city features a mix of different styles of decoration in the old building façade.
The existence of old buildings in Taipei together with the nature of the decoration with symbols to create a façade of the building and the city a special status, resulting in such a mixed residential and commercial building façade and state of chaos is behind the spontaneous process of bottom-up and its interesting ordinary people and cultural background. In this research, collected through the case based on the form of construction as the basis for classification, divide into mixed-shop house, mixed-apartment, mixed-first floor, mixed-building, the remaining space under the viaduct, mixed-temple as well as seven types of special mixed. The operation in first design, mixed-apartment mixed use to provide a new mixed residential and commercial point of view as a new way, through the old style apartments will be converted to explore an alternative mixed-use point of view. Mixed blocks are based on urban renewal, through the non-complete removal of the old houses the way, to retain most of the old buildings, new buildings will be set up in the old frame building into a model.
