The current government has pledged to build 1.5 million new homes over the next five years—an ambitious target of 300,000 homes per year. Yet, if history is any guide, grand political promises on housebuilding often run aground on the shores of economic reality, planning bureaucracy, and political inertia.
The Problem with Housing Targets
Political leaders have made similar pledges before. In 2007, Gordon Brown promised 3 million new homes by 2020. In 2015, David Cameron’s government pledged 1 million homes by 2020. The Conservatives’ 2019 manifesto set a target of 300,000 homes per year by the mid-2020s. And yet, despite these promises, Britain has persistently failed to reach these numbers in recent decades. The simple question is—why?

Has Britain Ever Built 300,000 Homes a Year?
To understand whether this target is realistic, we must look to history. The last time Britain consistently built over 300,000 homes a year was not in some distant, mythical past but during the 1930s—a period often overlooked in discussions about the housing crisis.

The 1930s Housebuilding Boom: A Different Britain
The 1930s stand out a highly productive decade for British housebuilding. Between 1930 and 1939, England and Wales achieved over 300,000 new homes per year multiple times, with peaks that modern governments have failed to replicate. But why was housebuilding so successful then, and why is it so difficult now?

1. The Absence of Planning Restrictions Unlike today, the 1930s had no green belts, no significant planning bureaucracy, and fewer restrictive regulations. Private developers could build quickly and at scale without being ensnared by local authority objections, environmental assessments, or protracted planning disputes. Ironically, many of the houses built during this period were aesthetically pleasing and well planned. Something that seems to have been lost since the introduction of planning controls.
2. Land and Labour Land was more affordable, and there were fewer barriers to its use. Britain was not yet burdened by modern zoning laws or the political resistance that prevents development in many areas today. Labour was also abundant and relatively cheap, ensuring that construction remained viable even during economic downturns.
3. Public and Private Sector Synergy While much of the 1930s boom was driven by private housebuilders, government incentives played a role too. Local authorities were actively involved in building affordable housing, and financial policies supported both developers and buyers. The government understood that the private sector needed room to operate freely while ensuring housing supply kept pace with demand.
The Structural Barriers of Today
Fast-forward to the 21st century, and we see a very different set of conditions. Britain’s housing market is locked in a vice grip of planning restrictions, vested interests, and financial constraints.
• The Planning System is slow, bureaucratic, and often hostile to development. Local opposition—from well-organised middle-class homeowners who benefit from rising house prices—frequently blocks major projects.
• The Green Belt, originally designed to prevent urban sprawl, now artificially restricts land supply, making housebuilding vastly more expensive.
• Labour and Material Costs are significantly higher than in the 1930s, exacerbated by supply chain disruptions and inflation.
• Financial Incentives are misaligned. While housebuilders are incentivised to control supply to keep prices high, there is little drive to meet genuine demand at scale.
What Can Be Done?
If Britain is serious about solving its housing crisis, it must confront these structural issues head-on. That means:
- Reforming the Planning System – Streamlining approvals, reducing bureaucratic delays, and enabling development where it is needed most.
- Reassessing the Green Belt – Allowing responsible development in areas that are not of high environmental value.
- Supporting Both Public and Private Builders – Encouraging both private-sector investment and public housing initiatives.
- Prioritising Homeownership – Ensuring that new developments cater to first-time buyers rather than buy-to-let landlords or foreign investors.
Final thoughts
The 1930s proved that Britain can build at scale when the economic and political conditions allow. But today’s political class lacks the appetite to tackle the vested interests that keep house prices high and supply restricted. Without radical reform, the housing crisis will continue to worsen, and future generations will be locked out of homeownership.
If Britain could build 300,000 homes a year nearly a century ago, why can’t it do so today? The answer is not a lack of ambition, but a system that no longer rewards those who build—but instead protects those who already own.
