Purpose: The objective was twofold: 1) summarize research-informed environmental characteristics into Mostafa’s seven ASPECTSS™ criteria for people who are aging, and for children who have autism, and 2) apply those characteristics within the context of a Green House planned intergenerational facility providing support to adult child with autism, and their parent(s). Background: The rate of Autism Spectrum Disorder (ASD) diagnoses is increasing, making it important to design spaces for people with ASD. Approximately 85% of children with ASD live with their parents (Mykyta, 2012). Ahrentzen & Steele (2010) identified the need to develop housing options for people with ASD. Method: Design considerations from a literature review were organized into two tables: 1) aging adults and 2) people who have ASD. Shared characteristics were placed into a third table using Mostafa’s seven ASPECTSS™ criteria, and then applied to the intergenerational facility plan to demonstrate the effectiveness of intentional planning by caregivers and the design community. Results: When integrating Mostafa’s ASPECTSS™ framework, and the intergenerational Green House Model, the application of design choices within housing demonstrates that appropriately designed space can positively impact persons and families with autism, regardless of age. Conclusion: Findings show numerous overlapping design criteria for people with autism and aging adults that can lead to effective environmental solutions for both. This facility type has the potential to minimize family fracture since aging parents are supported in their ability to care for their child with autism.
