The first wave of Baby Boomers will turn 65 in 2011, and the construction industry has been adapting to meet the needs of that wave of potential customers for several years. As far back as 2000, in a survey conducted by AARP, 71% of respondents 45 and older said they "strongly agreed" that they wanted to stay in their homes. The concepts and techniques of Universal Design are what will allow that trend to play out, as homes are built and remodeled to fit the changing needs of the population.
While the aging population has been the major driver behind the evolution of Universal Design, the basic concepts are not limited to that segment. The core idea behind UD lies in creating spaces that meet the needs of all people, young and old, able and disabled. It is rooted in seven basic principles:
Principle 1: Equitable Use
The design is useful and marketable to people with diverse abilities.
Principle 2: Flexibility in Use
The design accommodates a wide range of individual preferences and abilities.
Principle 3: Simple and Intuitive Use
Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or current concentration level.
Principle 4: Perceptible Information
The design communicates necessary information effectively to the user, regardless of ambient conditions of the user's sensory abilities.
Principle 5: Tolerance for Error
The design minimizes hazards and the adverse consequences of accidental or unintended actions.
Principle 6: Low Physical Effort
The design can be used efficiently and comfortably, and with a minimum of fatigue.
Principle 7: Size and Space for Approach and Use
Appropriate size and space is provided for approach, reach, manipulation, and use, regardless of the user's body size, posture, or mobility.
