Cities Don't Follow Master Plans, Here's What They Actually Follow

A colleague at work recommended this book with the pretext that this book is on the same lines as Kala Seethraman Sridhar’s Indian Cities or Suburbs. The comparison was fair enough on the surface. Both books deal with the question of how cities spread, why people and jobs drift outward from their old cores and what that means for the way we live. But when I finished the initial chapters of Alain Bertaud's Order Without Design, I knew I was in different territory altogether.

Sridhar’s book is a rigorous data-heavy examination of Indian urbanisation. Bertaud’s is something else: a career's worth of wisdom from a man who has actually been on the ground in over fifty cities, from post-independence Algeria to Soviet Russia to the booming urban cities of China, and who spent decades trying to bridge the enormous difference between economists who understand cities and planners who are supposed to design them. The result is a book packed with insights, global comparisons, and frankly a kind of intellectual honesty that is rare in urban planning literature.

What truly struck me was how many concepts Bertaud introduced that I had never even considered when thinking about cities. Parameters and frameworks I had simply never heard of. This is not a book that tells you cities are complicated — it shows you how they are complicated and then hands you tools to think more clearly about them.

If you have even a passing interest in why your city looks the way it does, why your commute takes the time it does, or why housing is so expensive, this book will change how you see the world.

The title, Order Without Design, is borrowed from a quote by the Scottish philosopher Adam Ferguson: cities are “the result of human action, but not the execution of any human design.” Bertaud’s central argument flows from this. Cities, he insists, are primarily shaped by markets; by millions of individual decisions made by households and businesses responding to prices, wages, rents and commuting costs. Planners can modify these outcomes through regulations and infrastructure, but they cannot replace the market's role as the primary organiser of urban space.

This might sound like a libertarian manifesto, but it is not. Bertaud is not anti-planning. He is anti-ignorance. His real frustration and the engine that drives the entire book is that the two groups who should be working together constantly talk past each other.

1. Urban planners, he argues, are “normative”: they decide how cities should look and impose that vision through regulations, often with little understanding of how markets work.
2. Urban economists, meanwhile, produce elegant theories and peer-reviewed papers that almost never reach a city planning department.

According to him, planners are “blind” (they act without seeing) and economists are “paralytic” (they see but do not act).

The book is Bertaud's attempt to bring these two worlds together, and it works because he himself has operated in both. He has written regulations, designed housing estates, drawn up master plans and also spent enough time with economists to understand why his early planning work often produced the opposite of what he intended.

If I had to identify the single most eye-opening framework in this book, it would be this: a city is, fundamentally, a labour market. Not a collection of neighbourhoods. Not a set of land-use zones. Not a canvas for architectural expression. A labour market.

What this means is deceptively simple. People move to cities because cities offer a concentration of jobs and the larger and better-connected the pool of jobs, the more productive and wealthier everyone becomes. The key variable is not how many jobs exist in a city in total, but how many jobs any given worker can reach within a reasonable commute. Bertaud defines "reasonable" as roughly 1 hour each way. The number of jobs accessible to you in that one-hour window is, in effect, the size of your labour market and it directly determines your wages, your career options, and your city's economic vitality.

This leads to a counterintuitive insight about transport. We usually think of roads and metro lines as a convenience or an amenity. Bertaud shows they are actually an economic multiplier. A study of Korean cities found that a 10% increase in the number of jobs accessible per worker corresponds to a 2.4% increase in productivity. For French cities, increasing average commuting speed by 10%, all else being equal, expands the effective labour market by 15 to 18%. Transport is not a luxury. It is the mechanism that turns a big city into a productive one.

The bar chart above is one of the most instructive in the book. Look at Gauteng, the South African metro that includes Johannesburg. Because of the legacy of apartheid (system of institutionalized racial segregation), which deliberately placed Black workers' townships far from white business districts a disproportionately high share of workers spend over 60 minutes commuting each way. This is not just an inconvenience. It means those workers can access far fewer jobs, earn lower wages, and face higher unemployment. Bad urban geography, enforced through decades of racist policy, continues to function as an economic tax on the poor. It is a sobering reminder that city-planning decisions are never politically neutral.

One of the most illuminating sections of the book involves something called the “density gradient” (a measurement of how population density changes as you move away from a city centre). Bertaud uses this tool to compare cities across cultures and income levels, and what he finds is both surprising and clarifying.

Every functioning city, it turns out, follows a remarkably similar pattern: density is highest at the centre and declines as you move outward, following an exponential curve. This is not a coincidence or a cultural preference. It is the market expressing itself through the price of land. Central locations are more accessible — to jobs, amenities, transport. So land there is more expensive, which means people consume less of it, which means more of them live per square kilometre.

What the grid of charts above shows is remarkable: Paris and Jakarta, New York and Mexico City, Bangkok and Los Angeles are wildly different cities but all follow the same basic exponential density curve. This is what a market-shaped city looks like. And this is also why heavy-handed regulations that try to impose "uniform density" or artificially limit density in city centres tend to backfire. When you prevent people from building densely in high-demand areas, you don't make the city more equitable; you push people and prices outward, expanding sprawl, lengthening commutes, and making housing more expensive everywhere.

Bertaud introduces another insight here that I found particularly sharp: the density gradient flattens over time as cities grow richer and transport improves. This is exactly the suburbanisation trend that Sridhar's book documents for Indian cities the "pancaking" of urban population across a wider footprint. But where Sridhar’s book treats this as a largely descriptive finding, Bertaud explains the mechanics: rising incomes increase people's ability to afford transport and more space, so they trade central location for larger homes further out. The density gradient flattens not because planning fails, but because markets work.

The chapter on mobility is one of the richest in the book, not least because of the striking data Bertaud marshals from around the world. One image that stayed with me is the trip pattern map of metropolitan Paris.

This image demolishes a romantic myth about Paris. We imagine it as a city where everyone goes to the centre to boulevards, to cafés, to grand offices. The reality, as Bertaud's data shows, is that the vast majority of daily trips in the Paris metro area are suburb-to-suburb. Workers are no longer commuting inward to a single downtown. They are criss-crossing the urban periphery to reach dispersed jobs in business parks, technology clusters, and service hubs. This is the "composite model" — a city with a still-significant but diminishing centre, surrounded by a web of polycentric movement.

The same trend appears in Seoul, New York, and across Asian megacities. The monocentric city — everyone commuting to the centre from the suburbs — has largely given way to a far more complex pattern. And yet many master plans, especially in India, still imagine cities as monocentric. We plan radial roads converging on a CBD (Central Business District), design metro lines to serve the city centre, and restrict land use in ways that assume most economic activity will remain central. They are, in short, planning for a city that no longer exists.

Bertaud's argument about transport is consistent; planners should not decide which transport mode to privilege and then shape the city accordingly. They should observe where people actually live and work — the emergent spatial structure produced by markets — and then design transport systems to serve that structure. Doing it the other way around almost always leads to expensive underused infrastructure or, worse, regulations that strangle the city's organic development to fit the transport plan.

The chapter on housing affordability is where this book becomes urgently relevant for anyone thinking about Indian cities, or indeed cities anywhere in the developing world. Bertaud's framework is simple but devastating: housing unaffordability is almost always a supply problem, and supply is almost always restricted by regulation.

To measure affordability across cities, Bertaud uses the Price-to-Income Ratio (PIR) — the price of a home divided by household income. A PIR of 3 means a typical home costs three years' worth of a typical family's income. Anything above 5 is considered "severely unaffordable." Look at where the world's major cities sit.

The chart is stark. Atlanta, with relatively flexible land-use regulation, has a PIR of 3.1 close to affordable. Sydney, Auckland, Vancouver, and San Francisco — cities celebrated for their planning and liveability have PIRs above 10. Bertaud's argument is that these cities have constrained their own housing supply through a tangle of zoning restrictions, height limits, heritage protections, floor-area ratio caps, and minimum plot-size requirements. These regulations were often well-intentioned. But their cumulative effect has been to price ordinary families out of cities that are also among the most economically productive in the world.

The South Africa case study is particularly striking. After apartheid ended, the government launched one of the most ambitious housing programmes in history, delivering 3.5 million subsidised homes to the poor. The homes were good quality — 65 square metres, proper roads, schools nearby. But because land in the programme's formula had to be cheap to accommodate the other costs, every project ended up on the far periphery of cities. Some beneficiaries ended up spending as much as 50% of their income simply getting to work. Comfortable houses in impossible locations became, in Bertaud's words, "poverty traps." The government made the trade-off decision for poor households — choosing floor space over location — when the households themselves, given a portable subsidy, would have made a very different choice.

This is the book's most important practical lesson: location is not a luxury. For poor or middle-class people especially, being near jobs, schools, and healthcare is not a nice-to-have; it is the entire point of living in a city. Any housing policy that ignores location is not solving the affordability problem. It is relocating it.

Across every chapter, a recurring villain emerges: the urban master plan based on a utopian idea about how people should live. Bertaud has seen these up close; Le Corbusier's Plan Voisin for Paris (which would have demolished historic districts to build uniform tower blocks in parkland), the Soviet Union's command-economy city planning, the "urban village" model beloved by smart-growth advocates who believe large cities can be broken into self-sufficient, walkable neighbourhoods where people live near where they work.

On the urban village idea, Bertaud is particularly sharp. Seoul tried it. Five satellite towns were built around the capital, carefully calibrated so that the number of planned jobs matched the number of planned residents in each town. The theory was that residents would work locally, eliminating long commutes and congestion. Surveys after the fact showed that almost nobody did. The residents of each satellite town commuted to jobs throughout the Seoul metro area, and the jobs in each town were filled by people living elsewhere. The urban village model, as Bertaud puts it, "exists only in the minds of urban planners." It contradicts the very reason large cities exist: a unified, accessible labour market lets employers find the right workers and workers find the right jobs. Fragmenting that market into small, self-contained clusters destroys the economic logic of the city.

None of this means planners have nothing to do. Bertaud is emphatic that planning is essential but its essential tasks are specific: building infrastructure ahead of growth (roads, water, sewer), reserving land for public goods that markets will not provide (parks, arterial roads), and auditing regulations regularly to remove the ones that have become harmful. What planners should not do is try to allocate land and floor space among users as if they had the information to know better than the market what is needed where.

Reading this book alongside Sridhar's Indian Cities or Suburbs? is a good experience.

Sridhar shows us what is happening to Indian cities: suburbs are expanding, density gradients are flattening, and services are struggling to keep pace with peripheral growth.

Bertaud gives us the theoretical architecture to understand why and, more importantly, what to do about it.

India's cities suffer acutely from the regulatory constraints Bertaud identifies. Floor Area Ratio (FAR) limits in most Indian cities are among the lowest in the world; in many cases, they effectively ban dense construction even in central areas where land prices are screaming for it. This is a key reason Indian cities sprawl: building up is restricted, so growth goes outward. The result is longer commutes, more expensive infrastructure, and less affordable housing. Mumbai, with its absurdly low FARs and massive cotton mill lands locked in decades-long legal disputes, is perhaps the clearest example. Bertaud would look at it and see a city whose regulations have been allowed to accumulate over generations without ever being audited for their actual impact on people's lives.

The other critical lesson for India is about the politics of location in housing programmes. State governments building affordable housing routinely place projects on cheap peripheral land, exactly as South Africa did. The cost arithmetic makes sense on a spreadsheet. On the ground, the result is families who can afford a roof but cannot afford to get to work. A shift toward portable housing subsidies — or, at minimum, a serious reckoning with the location costs of peripheral housing would do more for urban poverty than any number of well-designed tenements at the edge of nowhere.

Order Without Design is an honest, practically grounded book on cities. It is not an academic text, though it engages seriously with economics. It is not a polemic, though it argues a clear position. It is something rarer: the accumulated thinking of a practitioner who has spent a career watching the gap between how cities are planned and how they actually work, and who has written a book to help close that gap.

If you care about why your city is expensive, congested, unequal, and sprawling — and what any of that has to do with regulations written decades ago for a city that no longer exists — this book will give you more analytical tools than almost anything else one can recommend.
