Explain the concept of universal design and name one accessibility guideline.

• A. Universal design aims for spaces usable by people of all ages and abilities; guideline: doorways with at least 32-36 inches clear width and accessible routes with gentle slopes.
• B. Universal design is solely about aesthetics and visual appeal; guideline: maximize surface contrast.
• C. Universal design focuses on energy efficiency; guideline: use triple-glazed windows.
• D. Universal design requires all spaces to be identical for every user regardless of ability.

Answer: (A)

Universal design aims to create spaces usable by people of all ages and abilities, emphasizing inclusive, flexible features that work well for a wide range of users in everyday activities. This means designing for someone in a wheelchair, a person with limited mobility, a parent with a stroller, or someone aging in place, so the space remains accessible without needing special adaptations.

A practical guideline is to include doorways with a clear width of about 32 to 36 inches and to provide accessible routes with gentle slopes. This supports easy entry and circulation for wheelchairs and walkers and reduces barriers at key transition points.

This approach keeps usability front and center for diverse users, rather than focusing only on aesthetics, energy performance, or making every space identical for everyone.
