This study investigates two primary objectives: (1) to explore factors influencing perceptions of tourism safety among stakeholders—including homestay operators, community leaders, local residents, and tourists—on Koh Yo, Southern Thailand; and (2) to identify key architectural components for designing community-driven models of safe tourism. These models aim to enhance safety across various tourist settings while balancing sustainability and cultural preservation. Employing a mixed-methods approach, data were collected through in-depth interviews with 20 homestay operators and 10 community leaders, as well as structured questionnaires distributed to 360 local residents and 300 tourists, totaling 690 participants. Quantitative data were analyzed statistically, while qualitative content analysis provided deeper insights into stakeholders’ perceptions. Key findings emphasize essential design features, including accessible facilities for individuals with disabilities, clear signage, and reliable emergency systems. The study underscores the importance of community involvement in tourism planning, which enhances safety and supports sustainable, resilient tourism practices. This research offers practical recommendations for policymakers and developers, presenting a framework for creating inclusive, community-driven architectural models for safe tourism that can be adapted to similar destinations.
