Not functioning phone booth turned into a public bookshelf, DIY sidewalk furniture, or even illegal bike lanes, - all these civic-minded public space alterations exemplify Do-It-Yourself (DIY) urban design or DIY Urbanism – “small-scale and creative, unauthorized yet intentionally functional and civic-minded ‘contributions’ or ‘improvements’ to urban spaces in forms inspired by official infrastructure” (Douglas, 2014).
Such phenomenon challenges existing planning paradigm exploring and developing collaborative urban design approach, furthermore, demanding citizens as equal partners of an urban development process (Fabian & Samson, 2015). According to Douglas (2014), a significant number of DIY-urbanism activists prove noticeable knowledge of urban planning mechanisms, moreover, some of them contribute towards specific city goals. Understanding of broader impacts and long-term effects of urban fabric alterations, however, is out of their focus due to activist nature of the interventions. Two trends, namely theoretical acceptance of participatory urban design along with a lack of co-design projects treating citizens as equal partners, and the rise of civic-minded projects that aim informal alteration of public spaces born a the challenge of utilization and integration of citizen urban initiatives into wider urban planning context in order to sustain them.
