Voids and Architectural Regeneration: Systematic Review of Applied Approaches

This systematic review examines and critically classifies the strategies applied to abandoned urban voids through the analysis of peer-reviewed scientific and technical literature, addressing the lack of integrative studies on the topic. A systematic search was conducted in the SCOPUS database for articles published between 2000 and 2025, following the PRISMA 2020 guidelines. Sixteen studies that met the inclusion criteria were analyzed using the digital tool Parsifal. The results reveal that adaptive reuse and architectural regeneration are the predominant strategies for transforming abandoned urban voids, aimed at converting underutilized or abandoned spaces into functional and socially integrated urban assets. In contrast, approaches such as rehabilitation and environmental remediation appear less frequently but highlight the importance of ecological and preparatory interventions. This review also identifies gaps in the psychological and participatory dimensions, proposing their integration into future urban regeneration frameworks. This work provides an updated conceptual foundation for sustainable architectural interventions and emphasizes the need to expand research in diverse geographical contexts, particularly in Latin America.
