Some people seem to think that if buildings are made "accessible" for disabled or mobility-impaired people, that the result will be inconvenient for the able-bodied. Nothing could be more wrong. Principles of Universal Design (UD) promote the creation of environments that are easily usable by the greatest number of people, both abled and disabled.
In many cases, a UD approach increases the attractiveness of a space and makes it more convenient for everyone, regardless of physical ability.
For example, think about "rocker" light switches, which were developed to make it easier for disabled people to control the lights in a room. These switches are now considered a design "upgrade" over the old-style flip (or toggle) switches, and most people see them as part of the decor without knowing that they represent accessibility. This is only one example of how intentional accessibility benefits everyone.
Turning a round doorknob can be difficult, painful, or even impossible for people with common conditions such as arthritis, people with neurological conditions that limit hand function, people recovering from injuries, and people who have their hands full of packages. A lever doorknob solves this problem. It can be opened simply by pressing - no need to grasp and twist. If your hand is occupied (or in pain), you can use your elbow. In addition to being convenient, Levers can add beautiful designs and artistic flourishes to home decor.
Some people are reluctant to build ramps to the entrances of buildings, even though ramps make buildings easier to enter. There is a common misconception that a ramp always looks unattractive and detracts from the appearance of the building. Why would a staircase be better looking than a ramp?
Stairways can be dangerous, awkward to use, a barrier for children or others with short legs, miserable for the elderly or anyone who is tired or ill, impossible for some disabled persons, a blockade for strollers, shopping carts, walkers, and wheelchairs, and often quite ugly.
Architects have spent hundreds of years inventing ways to make stairs look good, despite all the problems they present. Stairs have been accepted as the normal way to get from one level to another. We see them everywhere, and have become so accustomed to looking at them, that we don't even notice how inconvenient and unattractive they are.
Some designers even add unnecessary steps to a space to create different levels because of some fantasy that it looks good or that it is a method to organize the way a space will be used. In what world are deliberately-created trip hazards good organization?
Unlike stairs, ramps are accessible to nearly everyone. When intentionally designed as part of a building's architecture, they look natural and may even be beautiful.
