A Brownfield is well described in various definitions and supported the idea to redevelop while indentifying numerous benefits for the society. Further on, the existing literature covers a broad range of different aspects of the Brownfield redevelopment thus elaborating different features. Still at present, there is no overview of the Brownfield features from the perspective of the real estate that focuses on the place and property, two fundamental principles of the development. At first this paper contributes with the literature survey that was deployed based on this perspective. Additionally, it focuses on the quantitative features relevant for the Brownfield Redevelopment that served as an input for the Fuzzy Delphi technique. It derived from the traditional Delphi method and fuzzy set theory. This rigorous procedure is based upon group thinking of the qualified experts that assures the validity of the collected information. It advanced the traditional method by downsizing the number of questionnaires in the survey and assuring that there is no misinterpretation of an expertís prime opinion thus genuinely reports their responses. This survey was deployed among the experts that are grouped and each one played a roll of a well described actor with the specific goals and tasks. This paper aims to give an answer if the different groups value the relevance of the Brownfield Redevelopment features same or not? Fuzzy Delphi technique proved to be an excellent tool to gather and abbreviate information for realizing the key features of the Brownfield redevelopment. This technique benefits on the operational dimension as well since accessing the relevant information through the huge database is often not accessible due to the different reasons.
