Universal Design & the ADA Design for Every Body

The idea that ‘form follows function’ is one of the basic concepts underlying nearly every design discipline—but function for whom? For many people living with disabilities, it often seems that ‘function’ covers a very narrow range of ability—rendering many forms clumsy at best, and completely useless at worst. While a cascading stairway might provide drama to a public space, for example, it may present an insurmountable obstacle to anyone making use of a wheelchair or other mobility aid. 

While in the past accessibility for differently-abled individuals may have been an afterthought (if it was a thought at all), in recent years, architects and designers have begun to change their view of how to best achieve form and function for everyone, regardless of age or ability. Two key drivers of that change were the adaptation of the theory of Universal Design, and the passage and implementation of the Americans with Disabilities Act (ADA).

Universal Design

“Universal Design was developed in 1997,” says Eric Cohen, senior associate principal at Ethelind Coblin Architect, an architecture and design firm based in New York with clients across the country. “It was the brainchild of a working group of architects, product designers, engineers, and environmental design researchers led by Ronald Mace at North Carolina State University. Universal Design is the design and composition of an environment so that it can be accessed, understood, and used to the greatest extent possible by all people regardless of their age, size, and ability. It is a fundamental process of good design.”

Cohen goes on to explain that there are seven principles of Universal Design: equitable use, flexibility in use, simple and intuitive use, perceptible information, tolerance for error, low physical effort, size and space for approach and use. Taken together and applied, these principles ensure that an environment can be used in the most independent and natural way, in the widest possible range of situations, by the broadest array of users, without special adaptation, modification, or specialized solutions. They can be applied to evaluate existing designs, to guide new ones, or to educate designers and consumers.

Jonathan Baron, principal of Jonathan Baron Interiors, also located in New York City, explains the movement in simple terms. “The concept came out of architects’ and interior designers’ concerns about meeting the needs of everyone, including mildly to severely disabled people. Something as simple as a cane or walker would have access to any space from a kitchen or bath to common areas such as lobbies and hallways. In the early 1990s this became a trend. It was the moment where the design industry took on the moral and ethical responsibility of this challenge. We weren’t going to design just anything anymore. It’s about ‘comfortable’ use. Form follows function. It is a commitment to meet the needs of everyone.”
