pronounced tranz-jeh-nuh-RAY-shu-nehl dih-ZYNE)
When you break down the words, this term makes total sense. “Trans” means to span or cross, so “transgenerational” means to encompass several age groups. Thus, transgenerational design is the deliberate practice of creating interiors, exterior environments and products that are user-friendly to the young, the elderly, and everyone in between. If you plan for young users, who might have height and dexterity issues, as well as the elderly, who might have vision, auditory and mobility issues, then everyone should be able to go about the activities of day-to-day living without major hindrances.
