The Planning Bureau is promoting the conservation and reuse of the historic site of the GolfCourse in Nanjing, which is the first golf course club built by Chinese, and a competition held inJanuary 2013 is the case study for this paper. At first, based on a debate on the heritage conservation of modernism, the rethinking of heritage conservation and reuse led to the following agreement: theheritage conservation and reuse must be dealt with together at the same time, thereby ensuring thelegitimacy of the conservation and restoration of the Golf Course in Nanjing. Then, based on theideas of planning projects taken from the competition for the Golf Course in Nanjing, the originalexcluded urban leisure space for ambassadors and political elites of the National Party Governmentwill be transformed into an inclusive space for the accessibility of the reuse of the heritage formore social groups. After that, a participatory planning process and public hearing to provide morecommunications with Nanjing citizens are proposed for the implementation in future. Finally, torespond to the theoretical problems in the beginning, rethinking the conservation and reuse ofarchitectural heritage is the focus of the paper’s conclusion.
