The UK is short of more than four million homes compared with the average European country, and the new Labour government has promised to build 1.5 million homes over the next five years — a pace not seen since the 1960s. A key part of that plan is reviving the idea of new towns, with settlements of at least 10,000 homes each. But the last time Britain tried this at scale, the results were mixed at best. Garden cities and new towns have a long, complicated history in the UK, and whether they can actually solve the current housing crisis depends on a lot more than just political will.

The idea sounds straightforward: build whole new towns from scratch, with affordable housing built in from day one. But the research shows a more complicated picture. Postwar new towns contributed only 3.3% of all housebuilding in the 40 years after the 1946 New Towns Act. And recent attempts, like Northstowe near Cambridge, have delivered barely a tenth of what was promised, with residents reporting poor amenities and long commutes. Here’s what you actually need to know.
The term garden city goes back to Ebenezer Howard’s late-19th-century vision of self-contained communities surrounded by greenbelt, with a mix of housing, industry, and agriculture. Letchworth Garden City (1903) and Welwyn Garden City (1920) were the first. After World War II, the 1946 New Towns Act created 32 new towns including Stevenage, Crawley, Bracknell, and Milton Keynes. These were larger and less utopian than Howard’s original idea, but they shared the goal of directing development away from overcrowded cities.
What new towns actually cost — and who pays
The headline figure is 1.5 million homes, but the real question is what it costs to get there. The postwar new towns programme built 307,000 homes between 1947 and 1991 — roughly the same number the government now needs to build every single year to hit its target. That gap alone tells you the scale of the challenge.
Costs have risen sharply. Higher land prices, labour shortages, and materials inflation all hit new town viability. On top of that, developers now face biodiversity net gain requirements, building safety regulations, and stricter energy efficiency standards. These add time and money to every project. With the public purse squeezed, the government will rely heavily on private sector investment — which means developers need to see a return.
That’s where the 40% affordable housing target gets complicated. Affordable homes generate less revenue for developers. If costs rise too high, the maths stops working, and either the affordable proportion shrinks or the project stalls. It’s a tension that has already played out in places like Northstowe, where slow progress has been blamed partly on viability gaps.
For buyers and tenants, the cost implications are direct. If new towns are built far from existing jobs and transport links, residents face long, expensive commutes. Northstowe residents reported exactly that problem. And if affordable housing targets slip, the homes that do get built may be out of reach for the people who need them most. What I tend to notice is that the gap between political ambition and on-the-ground delivery is where most of the risk sits.
Where the new towns plan goes wrong
Overestimating how much new towns can deliver
The Centre for Cities found that postwar new towns contributed only 3.3% of all housebuilding in the 40 years after the 1946 New Towns Act. That’s not nothing, but it’s far from a solution on its own. The mistake is treating new towns as the main answer rather than one tool among many. If the government pins too much on them, the overall target becomes harder to hit.
Ignoring the Northstowe lesson
Planning for a 10,000-home town near Cambridge began in 2007. By 2024, only 1,200 homes were completed. Residents who moved in a decade later found no shops, inadequate amenities, and long commutes to Cambridge. Over three-quarters (76%) said they were dissatisfied with local services. The mistake here is assuming that planning permission equals delivery. Infrastructure, services, and transport all need to arrive at the same time — or people won’t want to live there.
Underestimating viability pressures
Higher land, labour, and materials costs are squeezing margins. Add biodiversity net gain, building safety regulations, and energy efficiency requirements, and many sites become borderline unviable. The mistake is setting ambitious affordable housing targets without a clear plan for how to fund them when private developers walk away. If you’re involved in a property transaction related to a new town or garden community, getting the legal and financial details right matters. A real estate lawyer can help clarify contract terms, planning conditions, and affordability clauses before you commit.
Building in the wrong places
The housing minister himself acknowledged that new towns built too far outside commuting range won’t work. But the pressure to find large, cheap sites pushes developers toward remote locations. The result is car-dependent communities with poor access to jobs, schools, and healthcare — exactly the problems that garden cities were supposed to solve.
How new towns actually get built — the real process
Site selection and planning
The government’s new towns task force will recommend locations within a year. Sites need to be large enough for at least 10,000 homes, with access to transport and infrastructure. But finding land that meets all criteria is hard. Greenbelt land is politically sensitive, brownfield sites are expensive to remediate, and both face local opposition. The planning process itself can take years before a single brick is laid.
Development corporations and funding
Postwar new towns were built by government-funded development corporations that had compulsory purchase powers and direct access to Treasury funding. Today’s version will rely more on private investment, with developers taking the lead. That changes the incentives. Private developers need to sell homes at market rates to make a profit, which can conflict with the goal of delivering 40% affordable housing. The government may need to provide subsidies or tax breaks to bridge the gap.
Infrastructure and services
New towns don’t work without schools, GP surgeries, public transport, shops, and green spaces. These need to be planned and funded alongside the homes, not added later. Northstowe’s experience shows what happens when they’re not. The challenge is that infrastructure costs money upfront, but the revenue from house sales comes later. That timing mismatch is a major reason new towns take so long to deliver.
Emerging regulations and future changes
New towns built today must comply with biodiversity net gain rules, which require developers to deliver a 10% net gain in habitat value. Building safety regulations following the Grenfell tragedy add further costs and delays. And energy efficiency standards are tightening, with the Future Homes Standard expected to require low-carbon heating and high insulation from 2025. These are all positive in principle, but they add complexity and cost to projects that are already hard to make viable. For anyone considering buying in a new town, understanding the declining square footage of new builds is also worth factoring into the decision.

New towns alone won’t fix the housing shortage
The evidence from the postwar programme and recent attempts like Northstowe suggests that new towns are a slow, expensive, and relatively small contributor to overall housing supply. They can work, but only as part of a broader strategy that includes urban extensions, brownfield development, and faster planning approvals. The risk is that political enthusiasm for a grand vision overshadows the less glamorous but more reliable work of building homes where people already live and work.
