This text focuses on the phenomena of temporary appropriation (TA) as a transformative agent within performative arts environments. The concept of TA, commonly associated with the versatile use of urban spaces by individuals or communities, here is recontextualized in the realm of performative arts. This chapter explores how TA catalyzes the evolution and cultural contextualization of performative spaces, drawing from historical precedents where temporary interventions have redefined the spatial and experiential parameters of performance. Highlighting this interdisciplinary dialogue, the chapter illustrates case studies where ephemeral installations, pop-up theatres, and impromptu stages have served as platforms for artistic expression, challenging traditional architectural constraints. These modalities of TA reflect a broader trend towards flexibility, spontaneity, and inclusivity in the design of art spaces. The discussion will extend to encompass the socio-cultural impact of TA on community engagement, highlighting how these temporary setups can democratize art consumption and foster new artistic communities. Additionally, the chapter will examine the potential of TA to anticipate future trajectories in the design of performative spaces, emphasizing sustainability and resilience. It will propose design principles informed by TA practices, which prioritize modularity, adaptability, and ecological responsiveness. Through this lens, TA emerges as a pivotal concept for rethinking performative spaces to be more reflective of diverse artistic needs and environmental considerations. In conclusion, this chapter advocates for a reconsideration of design methodologies to embrace the temporal and adaptive nature of artistic endeavors, positioning TA as a driver for innovation and a bridge between historical evolution and future opportunities in performative arts spaces.
