Motives: The current approach to the design of public space in cities is changing due to the global situation, i.e., the climate and health crisis, as manifested by the COVID 2019 pandemic. There is a need to develop and apply new, innovative research methods and techniques that allow both an in-depth knowledge of a given area and the monitoring of the changes that occur in this area. One of the proposals for such a framework is an iterative model based on the results of the analyses carried out during the research and design work using the research through design (RtD) method.Aim: The aim of this study was to determine the applicability of the iterative process model for the development of urban strategy, particularly in terms of designing more resilient urban public spaces.Results: The iterative process model was tested during consultation meetings on the development strategy for the municipality of Polanica-Zdrój. The design concepts developed during the research were an excellent support for illustrating the goals of the spatial policy of the municipality of Polanica-Zdrój as specified in the draft of its development strategy. They became the starting point for the future design process. A project with blue-green infrastructure (BGI) elements was included in the draft development strategy as an exemplary project for the development and modernization of tourism and tourism-related infrastructure of a supra-local, infrastructural and linear nature. A study using the RtD method supported the identification of opportunities and limitations associated with the implementation of BGI in the protected urban areas.
