| Existing buildings as an urban civilization and historical context vectors, in the context of globalization and regional characteristics become identification era evoke memories of the place. However, with the change of social civilization development and people’s needs, existing buildings is lagging behind in the space of morphological and functional structure becomes contradictory advance reservations both historical context and urban civilization between the excitation point. Complete retention or complete removal of existing buildings are negative treatment as usual generic or brand-new building created nor is responsible for newborn recipe. How to guide existing buildings and new construction to spatial logic and orderly organization recognized the spirit of place for people to build their own and each other’s fusion research is discussed in the article we focus.In this paper which, the author follows the phenomenon from cognitive methods to summarize the logical sequence of "space center" as the starting point. Closely Firstly, based on the previous research on the theory expounded "space center" and "building perception" between,and from the multi-dimensional control mechanism and mode of action of the three elements of the concept of "space center" were systematic cognition. Then, through a large number of domestic and international case studies and induction, resulting from additions, alterations and new process "shift the focus of space," as well as the environment, human and historical factors guided "Reconstruction of existing buildings" two aspects of both dialectical relationship between were analyzed. Furthermore, through the retrofitting of existing buildings instance Friendly prototype extraction and graphic analysis, from the "physical props practices" and "semantic plot" the two aspects of the reconstruction of existing buildings and facilities in the spatial center of gravity of the specific control method classification elaborate. Finally, the development trend of the times and the author of the significance of existing buildings and facilities under the control of the center of gravity of space reconstruction are summarized and discussed. |
