Considerations of the built environment for autistic individuals: A review of the literature.
Soft lights, quiet walls, and clear sight-lines make any indoor space easier for autistic clients to tolerate.
01Research in Context
What this study did
Black et al. (2022) read every paper they could find on how indoor spaces affect autistic people. They looked at lighting, paint colors, room layout, and sound levels. The team then wrote a plain-language guide for architects, teachers, and clinicians.
The review covers homes, schools, clinics, and even dental offices. No lab work was done; the authors simply summarized existing studies.
What they found
Four small changes calm the nervous system: simple floor plans, dimmable lights, soft surfaces that soak up noise, and neutral wall colors. These tweaks lower sensory overload in any indoor setting.
The paper does not give effect sizes or participant counts. It simply states that studies repeatedly link these features to less stress and better focus.
How this fits with other research
Pimentel Júnior et al. (2024) agree. Their dental review shows that autistic clients skip appointments when clinics feel like echo chambers. They call for the same sound-absorbing materials Heather lists.
Howard et al. (2023) go one step further. They built an AI tool that auto-arranges classrooms using Heather’s rules. The algorithm beats human designers at placing quiet corners and soft lights.
McClannahan et al. (1990) might seem to clash. That older residential review warns that good homes need more than ‘soft lights.’ It stresses staff training and data systems. The gap is only in scope: E et al. cover whole programs, while Heather zooms in on the physical room itself.
Why it matters
You can act today without a grant or renovation crew. Bring a floor lamp with a dim bulb to your next session. Hang a cheap felt panel on the wall behind the learner’s chair. These two moves cut glare and echo, giving you cleaner data and fewer escape behaviors.

03Original abstract
Factors related to the interiors of buildings, including the layout of rooms, colours, smells, noises, temperature, ventilation, colour and clutter, among other things, can change the way we interact with our environment and the people around us. Autistic individuals can have differences in processing sensory information and may find aspects of the built environment (BE) over-whelming and difficult to navigate. We reviewed the existing literature exploring the BE and autism. This study found that it is possible to make changes to the BE to create more inclusive and friendly environments for everyone, including autistic individuals. Findings from this study provide clear recommendations that can be used by interior designers, architects, builders, and clinical practitioners to make a positive difference. Key recommendations include using simple spatial layouts, compartmentalising and zoning spaces into specific activity sections and providing retreat spaces. The thoughtful placement of windows and blinds and the installation of dimmable lights, for example, will allow users to manage or reduce sensory over-stimulation caused by lights. Similarly, we recommend creating soundproofing and sound absorbent materials to reduce background noise and sound levels. We also recommend using neutral or simple colour palettes and restrained use of patterns. Finally, and most importantly, the BE needs to be flexible and adaptable to meet the unique needs of each person. This study provides a starting point for design guidelines and recommendations towards making a difference to the everyday experiences of the interiors of buildings.
