The Key Findings
The researchers combined field observations, semi-structured interviews with healthcare professionals, and a careful literature review across three Alzheimer’s care centres in Turkey. They then compared what they saw with the well-known Fleming and Bennett design principles highlighted in the World Alzheimer Report 2020.
Three themes stood out.
Spatial layout mattered enormously. When corridors were short, sightlines were clear, and important rooms like toilets and dining areas were easy to see from communal spaces, residents moved more freely and needed less prompting. Long, repetitive corridors did the opposite: they raised confusion and agitation.
Sensory comfort shaped mood and behaviour. Good natural light, soft but even artificial light, warm colours on walls, low background noise, and familiar household furniture helped residents settle. Harsh institutional lighting and clinical materials made even well-staffed centres feel unwelcoming.
Small social spaces worked better than one big lounge. Little clusters of chairs, a kitchen table that could host two or three people, and quiet nooks off the main flow supported gentle conversation and reduced overwhelm. Staff also emphasised that global design principles only work when adapted to local culture, climate, and family expectations.
What Can You Take Away?
A dementia-inclusive building is not one grand feature. It is dozens of ordinary choices working together; shorter corridors, visible toilets, softer light, familiar chairs, quieter rooms, and small pockets of company. The environment can carry a lot of the cognitive load that a person with Alzheimer’s can no longer carry on their own. Get those basics right and staff can spend more time on people and less time on rescue work.
Implementation and Action
For care home leaders, this has been recommended for a number of projects but, walk through your building in the shoes of someone living with dementia and view it from their perspective. Can you see the toilet from where you sit at breakfast? Is the dining room obvious, or hidden behind a nondescript door? Small signage, contrasting door colours, and a rearranged lounge can shift daily life without a renovation. For designers and architects: keep corridors short, generous, and full of daylight. Break big communal rooms into two or three social zones with different furniture. Choose warm, matte, home-like finishes. Plan sightlines so key rooms are visible from where residents naturally sit. For families, notice which spaces your relative relaxes in and which ones agitate them. Share that with staff. A favourite chair, familiar cushion, or well-placed lamp can gently anchor a room.
The Critical Messages
Looking Forward
Many countries are building or rebuilding their aged care system, and small household models are already showing promise. This Turkish study reinforces what many architects and providers are pushing for, shorter corridors, more daylight, smaller lounges, and interiors that feel like home rather than hospital. The next step is larger studies that include residents and families as co-designers, and that test these ideas across our warm-climate, culturally diverse aged care context, including for First Nations and multicultural communities.
