The spatial design of therapeutic and rehabilitative institutions for children with autism spectrum disorder (ASD) remains a critical yet underexplored issue in contemporary China. Despite the rising prevalence of ASD among urban and left-behind children, accessibility to scientifically validated rehabilitation services remains limited, with high-quality interventions predominantly concentrated in metropolitan areas (Wang, 2016). Against the backdrop of China’s ongoing urban community health service system upgrades, this study investigates how community-based spaces can be designed to deliver effective ASD rehabilitation. Such spaces aim not only to alleviate core symptoms through sensory-adaptive interventions but also to equip children with essential life skills, thereby reducing social stigma and facilitating their integration into mainstream education systems. By bridging the gap between medical institutions and community resources, this research advocates for equitable access to quality rehabilitation services across socioeconomic strata.
