Universal, accessible, and usable design are all concepts that promote environments fit for everyone, including people with disabilities.

Universal Design proposes an evolving and progressive approach to developing inclusive built environments, whether an office or public space, which are highly usable and accessible to all individuals. Accessibility is essential when it comes to developing an inclusive environment. Creating accessibility in learning environments and physical spaces requires extra planning and thought at the initial stages. Universal Design, when implemented, could standardize built spaces for all abilities.
