The city of Split, due to the pressure of continuous urbanization and the absence of adequate green areas, is losing the quality of its environment. Contemporary solutions focus on naturalness and sustainability, therefore planning involves designing greenways and waterways in the cities and connecting them into a system of blue and green infrastructure. With that stated, the green infrastructure of Split has been examined/discussed and how a network of urban gardens could contribute to its improvement. Professional literature was used to describe the significance, benefits and development of urban gardens, and the results of the analysis were used to create diagrams of possible expansion and improvement of green infrastructure. By studying spatial planning documentation, conducting fieldwork and using software, proposals for possible locations for the establishment of urban gardens in Split were presented and placed in the context of the proposed development of Split’s green infrastructure. The research results include possible locations that, with interventions of a holistic approach, would enable a more connected system of green infrastructure. To ensure functionality, sustainability, and user satisfaction of future planned urban gardens, guidelines for designing a typical garden with necessary zones and defined possible content and purpose within the zones have been proposed.
