Bldg. 98-107 of Huifengxincun Community is the first experimental project based on the Open Building Theory in China. It was designed by Professor Jiasheng Bao from Southeast University at that time and finished in 1985. The base building (so called ‘support’) and fit out (so called ‘infill’) in the project was separated during the construction, so that the project owns much more flexibility than other housing at that time.

 In the last thirty years, researchers seldom made investigation on the community, so that the residents’ data and renovation history were missing. Besides, after thirty years of use, many problems occurred in the community, such as water leakage and common spaces not well-maintained. The author made the investigation on Huifengxincun Community three times in 2018, in order to collect the residents’ data and renovation history, find the existing problems, and find out ways to improve the living condition in Huifengxincun Community.

 Based on the three-time investigations, renovation history of 46 families was arranged, in which nearly 2/3 of them renovated the house by changing the furnishing and the plan of the rooms. The examples of water section change, however, seem to be not that much. Moreover, most of the families only made the renovation once throughout their living history. Examples of two dwellings combining into one can be seen in the community, and the function change, especially for the houses facing the street on the ground floor, are also seen in the investigations.

 Because of the improper management in Huifengxincun Community, some of the residents made unapproved reformation. Besides, the maintenance problem seems to become one of the great factors that stop younger generation moving in. As a result, how to deal with the maintenance problems need to be discussed. In spite of the problems, the construction details that are easy for renovation are proved to be effective for the residents to adjust their unit layout to the changes of the family structure and the changes of their lifestyles. In order to improve the living condition of the community better, the regular investigation on Huifengxincun Community is expected in the future.
