Architecture is defined as the art and science of designing buildings and constructed environment. While a constructed structure could be designed according to the requirements of the time period it had been built and met the requirements then in time it may lose its functions by the change of technical, technological and user habits. Architectonics is an indicator of material culture. Therefore material culture areas are important representative of the social heritage. In this respect besides the structures that can be preserved and be able to reach the present day the most of the ones which had lost its function and being idle are also the important elements of the public memory. The previous functions, plan and facade set ups interiors and the stories of the residents' of the buildings that lost its functions are a documentation of time, location and human interaction. Therefore, these structures also reflect the traces of a nation's historical and cultural past and the evolution on the geography in which it lives. There are buildings that have been exposed to numerous environmental, physical and damaging natural events and have lost their resistance in the course of time, on the other hand there are some ancient structures that can still stand with their robustness even today. Nowadays some structures can be used for different purposes other than their previous usages and the qualification of the structure due to the commercial pressures. Although the structures were going through a re-functionalization due to the different usages in the changing way of life there are valuable examples that brings them to present day by preserving the qualities and cultural heritage values of their period. Cities develop and evolve from past to present. In this context Istanbul always has been an important center of the ancifent civilizations by its strategic location that harbours the cultural accumulation of the centuries. That's why Istanbul still is an important metropolis of the world due to its multi-layered structure and cultural heritage. Although the boundaries of the Istanbul's raising population cannot be fully drawn, there is a need for social and spatial projects that can meet the requirements of the growing population. There is important heritage sites that need to be preserved and cherished in this city that has a quite amount of material heritage sites from the past. These heritage sites, besides being a material element, are the collective memory areas that emphasize the people's daily experiences, common history and common experiences. The Hasanpaşa Gazhane the subject of this study, is an important collective memory area in Istanbul Kadıköy. During the transition from the Ottoman Empire to the Republic, this center, which was an important industrial production area of its period has lost its function throughout the years and has severed its connection with the district to which it belongs and has become a structure group waiting in an idle state. Recreation areas are needed in order to realize the social activities of today's people in the growing cities. The commissioning of an industrial structure to the use of urban residents in the context of municipal's social policies with this purpose is a positive example that can be seen in many metropolises around the world. In this context, there are positive examples that have also been carried out in Istanbul. Hasanpaşa Gazhane which was built in 1891 has been went through a re-functionalization and commissioned to the public in 2021 by the Istanbul Metropolitan Municipality.
