A dark doormat that looks like a hole in the floor. A patterned carpet that appears uneven. These are just some of the ways dementia can change how people experience their surroundings, even within homes they’ve lived in for decades.
As the condition affects how the brain processes visual information, judging depth and distance – and recognising everyday objects – becomes increasingly difficult and hazardous.
Today, an estimated 83,000 New Zealanders live with dementia – a figure projected to nearly double by 2050 – with the vast majority remaining in their own homes.
Our work at the University’s Centre for Co-Created Ageing Research suggests basic design changes can make homes safer and more comfortable for people with dementia:
- Consider flooring. Consistent colours and tones tend to work best, as patterns or sudden changes in colour can be mistaken for obstacles or changes in depth.
- Contrast can make things easier to see. This might include using different colours for walls and floors, or making chairs stand out clearly against the floor. A black tap can appear more clearly against a white basin than a silver tap. Light switches are easier to find when they contrast with the wall around them.
- Clearing objects below knee height from floors can lower the risk of trips and falls. Removing or covering mirrors can reduce confusion and distress.
- Traditional k***s and controls on appliances and fittings can be much simpler to understand than sleek modern controls and touchscreens.
Dementia-friendly design doesn’t have to mean expensive renovations.
Steps as simple as taking away a confusing mat, using stronger colour contrasts, or making an important fixture easier to see can help make a home safer and easier to navigate.
To develop our new programme, we worked with Alzheimer’s New Zealand, The Village Architect, aged-care professionals and people living with dementia.
Our programme includes four new courses suitable for people with dementia, their whānau and caregivers, aged-care workers, architects, designers, and others involved in creating or adapting homes.
We developed a kaupapa Māori framework to guide design for people with mate wareware (dementia).
