Universal design is an approach to design that focuses on making all products and environments as usable as possible by as many people as possible regardless of age, physical ability, or situation. In recent years, the housing industry has recognized the importance of a “universal” approach to residential design that modifies standard building elements to improve a home’s accessibility and usability. This allows for more equitable, flexible and simple use. Many books exist on the subject, including Residential Remodeling and Universal Design: Making Homes More Comfortable and Accessible, a resource guide offered by the Department of Housing and Urban Development (HUD). HUD’s guide provides technical guidance on selecting and installing universal features during home remodeling or renovation. The modifications can range from expanding doorway dimensions to replacing kitchen appliances. The guide emphasizes eliminating unintentional barriers and using designs and features that could benefit people with a broad range of needs.
