“We built 300,000 homes a year in the 1930s. Why can’t we do it now?”
In the previous blog post, we looked at how Britain, in the 1930s, routinely built over 300,000 homes a year. That might sound like a distant memory, but it’s a memory with lessons. Because the fundamental question remains: if we could do it then, why can’t we do it now?
This post is not about nostalgia. It’s about facts. It’s about taking an honest, evidence-based look at what it actually takes to build 300,000 homes a year in the Britain of 2025—a Britain struggling with a housing crisis that is leaving an entire generation behind.
The Anatomy of a Modern House: Materials Breakdown
Let’s start with the bricks and mortar. A typical three-bedroom house in Britain today needs:
- 7,000 to 10,000 bricks
- 1,500 to 2,000 concrete blocks
- 20 to 30 cubic metres of concrete (for foundations and floors)
- 100 to 150 square metres of insulation
“A single house can consume up to 10,000 bricks. Multiply that by 300,000. Do the mathematics.”
These are not arbitrary numbers. They reflect the sheer material intensity of modern construction. And the demands don’t end there: plumbing, wiring, double glazing, heating systems, energy efficiency measures, and safety standards all pile on.
Compare that to the 1930s. The homes were simpler, yes. But they were also easier to build: fewer regulations, no requirements for insulation or double glazing, and no planning bureaucracy choking supply before a shovel even hit the ground.
Today’s building regulations are well-meaning—aimed at reducing emissions and improving living standards—but they also make housebuilding slower, more complex, and more expensive.
Time and Labour: From Foundation to Finish
If you’re wondering why we’re not building enough homes, here’s one reason: time.
“Building a house today takes nearly twice as long as it did in the 1930s.”
A typical house today takes 1,500 to 2,000 man-hours, or 3 to 6 months, to complete. And that’s with a skilled crew of 5 to 10 workers: bricklayers, carpenters, electricians, plumbers, and more.
Back in the 1930s, you could do it with fewer men and fewer hours—1,000 to 1,500 hours, start to finish. Why? Because homes were simpler, and red tape was almost non-existent.
Today, delays are the norm. Planning permissions can take months. Environmental assessments slow things down further. And the labour market? It’s stretched thin, with persistent shortages in key trades.
Scaling Up: The 300,000-Home Challenge
If we want to build 300,000 homes a year, we need to scale like never before.
“To hit 300,000 homes, we may need up to half a million workers and billions of bricks.”
Workforce required: Somewhere between 250,000 and 500,000 workers, depending on build time and overlap
Materials needed:
- 2.1 to 3 billion bricks
- 450 to 600 million concrete blocks
- 6 to 9 million cubic metres of concrete
Do we have the people? Barely. ONS data estimates the UK has between 700,000 – 1 million skilled construction workers, but only a fraction are in housebuilding. Do we have the materials? Not at current production levels.
Setting a housebuilding target without a plan to scale skilled labour and manufacturing capacity is going to result in failure.
We face a stark choice: either massively ramp up domestic production and training or face the uncomfortable truth that our current system simply can’t deliver what’s needed.
Some will point to modular housing as the silver bullet. Factory-built homes do offer promise, cutting build times and reducing weather delays. But the question is scale. Are we really prepared to invest in the infrastructure and workforce to make that viable?
Lessons from the 1930s and Barriers Today
The 1930s were not perfect. But they got one thing right: they built. And they did so because the state, industry, and society aligned around a shared goal.
They had:
- Cheap, available land
- Minimal planning regulation
- An abundant, skilled workforce
- Significant Local Authority house building capacity
- No centralised house building targets
Today we have:
- Green belt restrictions that stifle supply
- A planning system that rewards obstruction
- Land prices inflated by speculation and underuse
- A chronic skills shortage
- House building capacity is ovewhelmingly private sector. State / Local Authority capacity is virtually non existent
We need to ask ourselves hard questions. Do we want to keep prioritising bureaucratic process over practical results? Are we willing to challenge sacred cows like the green belt, in particular low grade agricultural land? Are we ready to invest in a new generation of skilled trades?
Solutions exist. But they require political will:
- Streamline planning in areas of high demand
- Relax restrictions on land use, especially near existing infrastructure
- Launch a national apprenticeship and training programme
- Rebuild our supply chains for materials like brick and concrete
Conclusion: Can We Build Like It’s the 1930s Again?
The answer is yes—only if we stop pretending that today’s failures are inevitable. They are not. They are the product of choices: political, economic, and institutional.
We need to recapture the ambition of the past, but marry it with the tools of the present. That means embracing innovation, cutting red tape, and putting housebuilding at the centre of our national mission.
“The housing crisis isn’t a mystery. It’s a supply and demand problem. And it can be fixed.”
The housing crisis is not just a technical challenge. It’s a test of our willingness to build again—at scale, with purpose, and with pride?
