Happy City by Charles Montgomery: Urban Design and Happiness

Happy City: Transforming Our Lives Through Urban Design (2013) is the book in which the Canadian journalist Charles Montgomery gathers the evidence from psychology, economics and neuroscience on a simple question: which urban design makes people happier. His answer, backed by decades of studies and cities on four continents, is that happiness depends less on income and house size than on three things planning decides: how much time we spend commuting, how much contact we have with other people and how much trust we feel in the place where we live.

Bogotá and the dignity of those without a car

The book's starting point is Bogotá under Mayor Enrique Peñalosa between 1998 and 2001. In a city with serious problems of poverty and violence, Peñalosa bet on cycle paths, the TransMilenio bus rapid transit system, pavements reclaimed from cars and parks and libraries in the poorest neighbourhoods, on the thesis that the city should give dignity to those without a car. Montgomery uses that case to show that urban happiness is not a luxury of rich cities but a decision about which space is given to whom.

The commuting paradox

The evidence on commuting is the most striking. The economists Bruno Frey and Alois Stutzer documented the commuting paradox: those who accept a long journey in exchange for a bigger house or a better salary do not make up in well-being what they lose in time, and would need to earn far more to break even. Every additional minute of driving reduces life satisfaction; walking or cycling, by contrast, increases it. Montgomery concludes that the dispersed city, which turns every task into a motorised trip, is an unhappiness machine, and that proximity is the most effective well-being policy.

Social contact, trust and the scale of the street

The second pillar is social contact. Happiness studies show that relationships, including casual encounters with neighbours and strangers, weigh more than almost any other factor. Design can enable or prevent them: Montgomery revisits Donald Appleyard's study of streets with traffic, Jan Gehl's experiments in Copenhagen and the data on trust in walkable neighbourhoods versus cul-de-sac suburbs. He also analyses scale: the long blank façades of large buildings bore people and quicken their pace, while streets with many doors and details invite them to linger.

Experiments that work and the trap of prefabricated happiness

Montgomery also visits the experiments that work. Vauban in Freiburg, an almost car-free district where children play in the street; central Copenhagen, pedestrianised in stages; cities that have turned car parks into squares and cohousing schemes where neighbours share kitchens and courtyards. He warns, however, of the trap of prefabricated happiness: Disneyland's Main Street or New Urbanist suburbs can imitate the form of the happy city without its diversity or its real public life.

Happy City is not a technical manual but an argument: urban design is a mental health and well-being policy, and should be evaluated as such. Its lesson for planners and citizens is to measure every project by what it does to people's time, contact and trust. Montgomery went on to found a lab that applies those ideas to real projects, and his book remains the most widely read introduction to the relationship between urban form and happiness.
