The built environment profoundly shapes the daily experience of people living with dementia. Thoughtfully designed spaces can enhance autonomy, reduce confusion, and create moments of joy. This engaging seminar explored the critical intersection of living well with dementia and environmental design, focusing on how the strategic integration of dementia-friendly considerations, natural daylight, and accessible outdoor spaces transformed people's days. Experts shared evidence-based approaches and practical solutions for creating environments that honoured dignity, supported independence, and enhanced well-being for those navigating the dementia journey. Attendees learned how mindful design choices—from lighting to wayfinding and sensory elements to safer walking—created spaces where people with dementia thrived, not just existed.
