The Dementia Enabling Environments website has a page on home design ideas. Some of them are simple and cost nothing, but might not be obvious to the casual observer. The Adapt a House page has a floor plan of five rooms: living room, kitchen/dining, bedroom, bathroom and laundry. It’s interactive, so clicking on a room brings up more detail. For example, in the kitchen they suggest see-through doors on wall cabinets. If replacing an appliance, match it closely to the existing one. In the bedroom colour contrasts are important for finding the bed and other furniture. Block-out blinds on the windows help differentiate between day and night, especially in the summertime. There is lots more information and resources on the website.
The Dementia Enabling Environments web tool was developed by Alzheimer’s WA.
