In 1992, Yvonne van Amerongen was working at a nursing home in the Netherlands. The care was competent. The building was clean. The residents — people with dementia, in the final years of their lives — were confused.

Not about their disease. About their environment.

"What we saw every day was that the people who lived in our nursing home were confused about their environment," she would later say. "Because what they saw was a hospital-like environment: doctors, nurses, and paramedics in uniform. And they lived on a ward. And they didn't understand why they lived there, and they looked for the place to get away. They looked and hoped to find the door to go home again."

Van Amerongen asked a question that sounds obvious only in retrospect: if the confusion is caused by the environment, why don't we change the environment?

Together with colleagues Jannette Spiering and later Eloy van Hal, she spent the next seventeen years answering it. The answer opened in December 2009, just outside Amsterdam in the small town of Weesp: De Hogeweyk, the world's first dementia village.

Hogeweyk is a village in the fullest sense. It has a town square, a supermarket, a pub, a theater, a hairdressing salon, gardens, and twenty-seven houses where six to seven residents live together, grouped by lifestyle and background. The staff do not wear uniforms. The amenities are operated by real cooks, waiters, and shopkeepers. Residents are free to walk around the village, sit in the cafe, buy things at the supermarket. There is one monitored entrance. Inside, everything is as normal as possible.

The result is measurable. Residents are more active than in traditional nursing homes. They require less medication. They experience fewer episodes of extreme anxiety or aggression. They live longer. The cost is identical to a standard Dutch nursing home, because Hogeweyk operates within the same government-funded budget. The only thing that changed was the design.

Since 2009, van Amerongen and her colleagues have consulted with institutions in Norway, New Zealand, the United Kingdom, Canada, Australia, and the United States. Dementia villages modeled on Hogeweyk have opened in multiple countries. The concept has been replicated not because it is expensive or technically complex, but because — once you understand what van Amerongen understood — it is obvious.

Hogeweyk is not a medical innovation. It is an urban design innovation. The insight is that the environment a person lives in is not separate from their care. It is the care.

Tokyo 🇯🇵 — Japan has 30% of its population over 65 — the highest proportion of any country on earth. Tokyo's care infrastructure for elderly residents is technically sophisticated: robotic assistance, smart home monitoring, community health networks. But the Hogeweyk insight — that the design of the environment is itself a form of care — has not yet produced the kind of radical physical redesign that van Amerongen achieved in Weesp. Japan's nursing homes are better than most countries'. They are still, in most cases, institutions. Tokyo has the scale and the motivation to build something like Hogeweyk at a level that would be a global model. What it has not yet found is the Yvonne van Amerongen who asks the question clearly enough that the answer becomes obvious.

Seoul 🇰🇷 — South Korea is aging faster than any OECD country. The country that built the Hallyu cultural wave and the most sophisticated consumer technology market in Asia is now building, urgently and somewhat desperately, an elder care system for a demographic shift it did not adequately prepare for. Seoul's approach has been largely institutional: specialized hospitals, geriatric centers, government-funded care facilities. Hogeweyk offers a different logic entirely. The question is not how to provide better medical care for elderly people in institutions. It is whether the institution — the building, the ward, the uniform, the routine — is itself a form of harm that no amount of medical care can undo. Seoul has not yet asked that question at the level of urban policy.

Singapore 🇸🇬 — Singapore has been integrating elder care into its urban planning for decades. HDB housing estates are designed with elderly residents in mind: lifts on every floor, grab rails, barrier-free access, sheltered walkways, proximity to clinics and community centers. The city-state's approach to aging in place is among the most systematically designed in the world. What Singapore has not done — and what Hogeweyk represents — is the radical reframing of dementia care specifically. The Hogeweyk insight is not about making cities more accessible for elderly people. It is about making the environment itself therapeutic. Singapore's systematic urban design capacity is exactly the infrastructure through which a Hogeweyk-inspired approach could be scaled. No other city in the world is better positioned to do it.
