|The research about spatial aspects of Sykhiv residential area can be considered a rather abstract task, despite the specifics of the physical form of mass housing. Given that the space of modernist districts is often interpreted as one with consistent attributes inherent in the “post-” context, the studio was intended to rethink the morphology of Sykhiv, combining spatial analysis with research on practices and perceptions. To do this, it was necessary to outline the specific type of urbanity with transformational structure, dynamic boundaries, and hybrid processes. The participants of the studio—Mariya Benovska, Oscar Damerham, Kacper Kępiński, Jana Kočková, Alla Onopchenko, and Aliaksandra Strashynskaya—are representatives of various disciplines (architecture, city planning, landscape design, urban studies, social studies, political science) and geographies of academic and living experience (Belarus, Great Britain, Australia, Estonia, Ukraine, Sweden, Poland, France, Czech Republic, Hungary, and elsewhere), which helped us to look at the area in the broader context. Therefore, we tried to form a common theoretical and methodological basis in the form of a dialogue between the disciplines and the academic approaches of the participants. The central issue of the studio was related to the physical space, which, however, was determined to a greater extent due to the “intangible” properties of the environment. During the first discussions we conducted “mapping” of the experiences and research interests of the participants. By supplementing it with field observations, we decided to stay on the topic of “water” in the broad sense, which is relevant both for the area and close or interesting to each researcher. Therefore, we tried to interpret the initial interest in the research on water from different perspectives: water Introduction: Spaces Natalia Mysak consumption culture, the right to water, water as a resource, water as a part of artificial landscape in the general planning hierarchy of the neighborhood and district, etc. We highlighted two research questions in our study: “How does water influence the formation of the living space of a residential area?” and “How does the formation of the living space area affect water?” The methodology was built on the intersection of interpretations of water concepts and modernist design principles. Taking into account that one of the central intentions of modernist planning (to reduce the functional links between objects) was not implemented when the political and economic contexts changed, new connections and transformations of morphology began to emerge in residential areas. How do these links interact with “water” as a basic daily need, or, for example, a seasonal need for recreation or healing? The application of the concept of service radiuses in the structure of the micro-districts allows us to rethink the meaning of this planning method. Also, the participants of the studio tried to make a direct impact on the environment using artistic means: an intervention by the sound of water in the place of a dry fountain, which, according to the inhabitants' memories, worked only twice. It can be considered as a research method and as a way of activating the inhabitants, an opportunity to convey the collected information on water (the map of the water objects of Sykhiv), both available and lost. It is important to note that the theme of water management is becoming increasingly relevant for the city: recently it was addressed at the level of experimental educational and municipal projects. We hope that the developed methodological concept can be further adopted for the study of Sykhiv and other modernist areas, and the group essay “Fluid Spaces” will become a small contribution to finding alternative ways to analyze the concept of “water” in urban space, particularly, in Sykhiv and Lviv.
