This paper examines the evolving field of tactical urbanism, offering a comprehensive analysis of its application as a strategy for sustainable urban regeneration. The research utilizes a bibliometric approach to analyze a diverse corpus of literature and includes case studies such as guerrilla gardening, pop-up plazas, and PARK(ing) Day to demonstrate the impact of these low-cost, community-driven interventions on urban spaces. By employing an iterative methodology adapted from Design Thinking, the study underscores the significance of community engagement in fostering effective and enduring urban transformations. The discussion critically assesses both the short-term and long-term economic and social effects of tactical urbanism, highlighting its potential to stimulate broader urban renewal initiatives. The findings indicate that although these interventions are often viewed as temporary, they can create lasting connections and significantly influence urban development. The paper also introduces a new cyclical methodology specifically designed for tactical urbanism, which incorporates community participation, creative ideation, and continuous feedback to enhance and scale urban interventions. This proposed framework aims to balance innovation with sustainability, ensuring that tactical urbanism plays a crucial role in the long-term vitality of urban environments.
