UNIVERSAL DESIGN is when you create something new in the world, you think about all of the people who can use it, not just people who are walking, people who can hear, people who can see you really need to be more thoughtful so that the design, first of all, is functional, and then of course, it's very attractive and beautiful. So, universal design is the design of spaces so that everybody can use them, but they're adaptable the with least amount of effort.
