Sensory Overload: How People with Autism Experience the World

Adults and children with autism experience the world much differently than we do, so why don’t we design homes, parks, and neighborhoods with them in mind? To do this, designers need to take into account the diverse range of experiences for people with autism spectrum disorder, who now account for more than 1 percent of the population. It truly is a spectrum of disorders. As Sherry Ahrentzen, professor of housing studies at the University of Florida and co-author of the upcoming book, At Home with Autism: Designing for the Spectrum, explained at the Environmental Design Research Association (EDRA) conference in Los Angeles, “if you know one person with autism, you really know just one person with autism.”

Autism spectrum disorder is a “psychological, cognitive disorder that creates intellectual and mood disabilities.” People with autism have a “blend of cognitive strengths and weaknesses.” In general, they have the capacity for “detailed thinking, expansive long-term thinking, and examining complex patterns.” But they have problems with “understanding social nuances, filtering stimuli, and planning daily living.”

However, Ahrentzen argues that “autism isn’t just a medical condition, it’s also a cultural one.” To help people with autism, “we must first acknowledge the diversity of human conditions.” To do this, we must understand that “disability is really a social construction. We create environments that enable or disable people.”

Kim Steele, director of urban and health initiatives at the elemental group, co-author of At Home with Autism, has a daughter with autism. In her effort to create a more empathetic environment for her, Steele seems to have truly learned what it means to have autism. Steele and Ahrentzen also interviewed many people with autism to better understand how they experience the environment and to create design guidelines that will improve their quality of life:

“People with autism focus on details, not global perspective. A fleck of white on a shirt, a flickering light, a noise command attention. Their default is too many details.” While this focus may work well for some types of work that are repetitive and require attention to detail, “it can be a huge problem, as too much input is stressful.” For example, Steele’s daughter will flap and rock to help refocus attention into something more manageable. “Outside, in the neighborhood, she will fall on the ground and collapse when the details are too much.”

To alleviate the stress from all this stimuli, planners, landscape architects, and architects need to make the built environment “more predictable and familiar,” perhaps simpler. For example, for most of us, the “kitchen is a place to prepare food, socialize, and eat.” For those with autism, “it must be a place to prepare food only, you eat and socialize somewhere else.” In another example, Steele explained how hallways can only be seen as conduits. They are not places to stop and talk. “Multi-functional spaces are not acceptable. The meaning is environments is very specific.” To help those with autism, designers must create places that “create transparency through spatial sequences and smooth transitions between uses.”

Those with autism have various levels of receptivity to the environment, so creating quiet, safe spaces with high-quality lighting is important, too. “Some display hyper-receptivity. This means they may have a problem with noise.” For one person with autism they spoke to, “the noise was so disorientating, she couldn’t find her body in space.” However, in contrast, some people with autism experience “hypo-receptivity, meaning they are under responsive to stimuli.” Steele’s daughter has this issue. “She can touch a hot stove burner and not realize she is burning herself. She can scald herself in the shower and not know it.”

Outside the home, smaller spaces with fewer details may be better. For example, those with autism avoid big box stores. “The acoustics and lighting are bad.” According to one person with autism they interviewed, they only go to small shops, which are more manageable.

For landscape architects, those with autism will want residential landscapes and public gardens and parks that are “controlled environments they view as safe.” They will also want “things you can lift, engage with.” They like swings and “almost universally love to swim.” In fact, those with autism will be “drawn to water in all forms,” which can also be dangerous. “Designers will need to create safe swimming pools.” But Steele also cautioned that hyper-receptive people will be overwhelmed with “gardens with too many different plants.”

Eve Edelstein, New School of Architecture & Design, said that “moving through any environment involves the same plastic part of our brains.” Edelstein, a leader in the emerging field of “neuro-architecture,” argues that design guidelines for indoors then relate to outdoors, too. “What we learn works for hospitals will also work in gardens. It’s about brain function in space.” She added that what will be good for those with autism will also work for those with a range of other disabilities, like post-traumatic stress disorder (PTSD).

Edelstein believes the journey from theory and design guidelines to actual practice in the world at large will be a “tough one.” An interdisciplinary design approach is a must for any project that will be more soothing to those dealing with the constant onslaught of too many details.

Mikyoung Kim’s Fractal Landscapes

“This is the image that sits above my computer screen. It’s a fractal form, which explains how we work. Within fractals, there are similar forms but at different scales. The molecular scale and broad scale work together as a whole. Fractals are a system. You can’t draw an outline of a fractal and fill it in, or create a bottom-up modular system and put one together. Fractals are about the overarching structure,” said Mikyoung Kim, FASLA, head of her namesake landscape architecture firm, in a lecture at the National Building Museum.

Fractals relate to her creative process. Just as at the broad scale — or the aerial view — you can see human behavior patterns, at the molecular scale, she is thinking of “one person, and their multi-sensory experience within that place.” However, having said all of that, Kim also believes that landscape architects “can’t predict how a public space will be used and allow for flexibility.”

Kim described a few projects that show her attention to both the broad and human scales, and how they fit together into a system:

ChonGae Canal Source Point Park: Sunken Stone Garden

She won an international design competition to create the ChonGae Canal Source Point Park, with its Sunken Stone Garden in Seoul, South Korea. For Kim, it was a great experience working there, as she is a Korean American born in Hartford, Connecticut. She discovered that Seoul has 22 million people, which is about half the population of South Korea as a whole. It’s 8 times denser than NYC, with 16,000 people per square mile.

The 7-mile-long ChonGae Canal was once a river that collected water from surrounding mountains. The river was one of the reasons Seoul became the capital of Korea in the late 1300s. Over the decades, it became a conduit for wastewater and raw sewage. “By the early 1960s, it had become a symbol of poverty, and so dangerous that you couldn’t even touch the water.” It was eventually covered over with an elevated highway, dividing the city.

The Seoul government took down the highway and decided to open up the river again. They brought day light back to the corridor and improved the water quality to class 2 level, which was really difficult. The new river corridor park had to handle monsoons and 100-year storms. “But, really, it was about bringing back national pride.”

Kim worked with the international team restoring the river, but focused on one piece: a stone garden at the source point. With this project, Kim realized landscape architecture can have significant political impact. This landscape has caused the city to rethink its relationship with the water, and changed perceptions about what’s possible with public space.

Also, the landscape itself is politically charged. In the era of the optimistic “Sunshine Policy” just a few years ago, when South Korean leaders thought reunification with North Korea was imminent, the ChonGae Canal Source Point Park was to be the site of the reunification ceremony.

There are ceremonial aspects of the landscape: Kim set 9 stones to represent the 9 provinces of Korea as a whole. The stones represent the “collective effort of this urban park, adding a layer of cultural significance.” Beyond the cultural aspect, Kim says the park, which has been visited by 20 million people since its opening, has led to $600 million in private sector development along the river corridor.

Through the Sunken Stone Garden, Kim came to the conclusion that the “most successful projects are ones where we don’t have to hire a photographer. If we can find lots of photos through Pinterest, Facebook, Flickr, we’ve been successful. Successful public spaces are canvases with a design language and character, but can embrace different kind of activity and discovery.”

Farrar Pond Residence

Kim said she does very little residential work, but she created a 3-acre landscape in Lincoln, Massachusetts, which links to Walden Pond. The clients had but one requirement: no lawn, but an outdoor space were the kids and dogs can run. They ended up deciding there would be no imperious surfaces on the property.

“The big star of show is this CorTen fence structure that contains the dogs. Our client was really two German Shephards.” The fence is designed to just keep these particular dogs in. Kim’s team measured the dogs from shoulder to shoulder to determine what the width of the fence openings should be. A dachshund that visited was able to slip right through. The fence was welded on site, so it fits the regraded landscape “like a glove.”

On the ground are lilac bluestone pavers and granite stepping stones. As her client said, “it looks like the void of fences have fallen out to create this pattern.”

140 West Plaza: Exhale

“We like smaller cities where we can make an even bigger impact.” In Chapel Hill, North Carolina, a “charming, historic university town, ” Kim worked with local developers to create a master plan for a new downtown park. Kim and her team concurrently looked at circulation, including bicycle infrastructure, plazas, and stormwater. They found that the mixed use developments were creating lots of surface stormwater run-off.

So Kim created a brilliant solution called Exhale. Instead of storing the run-off in gardens, she convinced them to exhale the cleansed runoff through an artful misting system. “If there is no extraneous water from the site, there is no mist.” Kim choreographed the experience, creating a score of sorts, with light and mist, which grows and dies back. “It’s like the sculpture is breathing.”

At night, Exhale is a magnet, particularly in the hotter months when the mist is on, as it reduces temperatures by 10 degrees. “Kids are willing to get soaking wet. They run and around and engage it.”

The Crown Sky Garden: Ann & Robert H. Lurie Children’s Hospital of Chicago

“I’ve always really been into healthcare. And now, healthcare is interested in us. Every facility wants a garden, which is much different from 20 years ago.” Still, at the Ann & Robert H. Lurie Children’s Hospital of Chicago, Kim felt pressure to deliver. “We were taking 8,000 square feet out of a vertical hospital to build a garden instead of a new MRI center. How does that equal out?” While she said her husband, who is a doctor, would take issue with the statement that “gardens heal people,” gardens do “transform our bodies in ways that can’t hurt. Within 3-5 minutes, it has been proven that gardens normalize blood pressure, heart activity, muscle tension, and brain electrical activity.”

In this healing garden on the 11th floor, there were enormous constraints. Given so many young patients there have weak immune systems or just had surgery, they couldn’t be exposed to organic materials like soil or plants. There have been cases of people catching Legionnaire’s Disease from fountains, so water features were out, too.

Kim and her colleagues finally convinced the hospital to allow bamboo in raised planters that patients wouldn’t be able to access. The soil that holds them is 98 percent inorganic. “Basically, the only thing that will grow in soil like that are weeds, and bamboo is a lovely weed.” The hospital staff have committed to putting a tarp on the bamboo and spraying them three times a year to keep them clean.

To get around the fact that no open water could be allowed, Kim created water features that bubble up through marble. And a fallen tree, which Frederick Law Olmsted planted in a park in Chicago more than 100 years ago, was reclaimed and turned into wonderfully tactile benches and interactive art pieces. Sealed together with resin and lit from within, the tree sculptures also feature kids’ hand prints, which when touched, activate sounds of water.
