The Housing Target Trap
The mainstream media loves a savior narrative. When Andy Burnham announces a pledge to build 10,000 genuinely affordable homes across Greater Manchester, commentators Nod along, debate whether volume housebuilders have the capacity, and ask if the planning system is fast enough.
They are asking the wrong questions.
The lazy consensus assumes Greater Manchester’s housing crisis is a supply problem that big private developers are failing to solve. The naive belief persists that if politicians lean heavily enough on housebuilders—or build a few local authority development vehicles—the math will magically work out.
It won't.
I’ve watched municipal authorities burn millions chasing this exact dream. The reality is far more brutal: Burnham’s housing ambition is built on a fundamental misunderstanding of developer margins, capital allocation, and the economics of modern construction. We aren't failing to build homes because housebuilders are lazy or evil. We are failing to build them because the state has made building low-cost housing financial suicide under current delivery models.
The Economics Nobody Wants to Talk About
Let's dissect the core mechanics. Housebuilders are not public services; they are machine-like capital allocation engines answerable to institutional shareholders.
When a corporate builder looks at a brownfield site in Salford or Stockport, they aren't looking at "community transformation." They are looking at return on capital employed (ROCE).
Land Acquisition + Remediation + Construction Costs + S106 Liabilities = Total Cost
Total Development Value - Total Cost = Gross Profit Margin
Private developers target a minimum gross margin of 20% to manage downside risk. When you demand that 30% to 50% of a scheme be locked into "affordable" or social rents, you obliterate that margin unless land value falls to zero. But land value doesn't fall to zero, because landowners would rather hold the site for another decade than sell at a fire-sale price.
So what happens?
- Developers sign up to ambitious planning obligations to get permission.
- The economic reality sets in three years later during site clearance.
- They return to the council with a viability assessment proving the scheme will go under unless affordable commitments are slashed.
- The local authority caves, because 500 market-rate homes are better than a vacant, fenced-off lot.
This is not a policy failure; it is a structural certainty. Asking private housebuilders to solve a social housing shortage is like asking an airline to run a free bus service—it flies in the face of their basic operating model.
The Small Builder Fallacy
When politicians realize volume housebuilders won't deliver cheap homes out of the goodness of their hearts, they pivot to their favorite romantic narrative: "We need to empower Small and Medium Enterprise (SME) builders."
It sounds great at a press conference. It is completely detached from reality on the ground.
SME builders are practically extinct in the UK, and they aren't coming back to save Greater Manchester. In the late 1980s, small builders delivered nearly 40% of all new homes. Today, that number sits below 10%.
Why? Because the regulatory burden acts as a massive tax that scales inversely with company size.
- Planning Delays: A two-year wait for planning approval costs a major housebuilder a fraction of a percent of its cash reserves. That same delay bankrupts an SME paying 12% interest on a stretch-senior development loan.
- Nutrient Neutrality and Biodiversity Net Gain: Compliance costs require specialized consultants, ecologists, and legal teams. Big builders retain these teams in-house. SMEs pay exorbitant third-party day rates.
- Capital Requirements: Banks used to lend 80% Loan-to-Cost to local builders. Post-2008 financial regulation destroyed that risk appetite. Today, debt funds demand eye-watering interest rates and pre-sales guarantees.
If Burnham thinks a army of local SME builders will miraculously appear to construct thousands of low-margin affordable homes, he is dreaming. The market has been systematically engineered to favor deep-pocketed oligopolies who survive on high-margin, slow-drip developments.
Pumping Capital Into a Broken System
So, what about direct municipal intervention? The rise of council-owned housing companies was supposed to bypass private sector greed.
I’ve analyzed the balance sheets of these municipal entities. The vast majority are disasters waiting to happen. They take on local authority borrowing, hire expensive consultants to manage project delivery, pay top-market rates for tier-one contractors, and then discover they lack the operational scale to manage the properties efficiently.
Imagine a scenario where a local council raises £50 million via the Public Works Loan Board. They buy three complex sites, hire a project management firm, and run into unexpected ground contamination. By year three, they have spent £12 million before pouring a single slab of concrete. The unit cost of their "affordable" housing ends up 30% higher than if a private developer built it.
This isn't hypothetical; it is happening across the country. Municipalities do not possess the procurement muscle, risk tolerance, or speed of execution needed to build at scale. Direct state intervention without systemic reform is simply burning taxpayer cash to subsidize inefficient supply chains.
How to Actually Fix the Deadlock
If you want to create real housing capacity in northern cities, you have to abandon the obsession with forcing private developers to act like charities, and stop pretending councils can become mass homebuilders overnight.
1. Kill Section 106 Haggling Completely
The current negotiation process around affordable housing contributions is an opaque, corrupting drain on time. Replace it with a fixed, non-negotiable infrastructure tariff based strictly on square footage. Strip out the viability assessment loophole entirely. If developers know the exact cost from day one, land prices will adjust downward accordingly.
2. Radical Public Land Grants
If the state wants genuinely affordable homes, it must contribute the one thing it controls: land. Greater Manchester public bodies own vast tracts of derelict, underutilized land. Stop auctioning this land to the highest bidder to cover short-term budget deficits. Transfer it to non-profit housing providers and community trusts at zero cost, bound by perpetual affordability covenants.
3. Fast-Track Modular and Off-Site Construction
Traditional brick-and-block construction cannot scale fast enough due to acute trade labor shortages. Modern Methods of Construction (MMC) have suffered high-profile failures because developers tried to build custom factories for single projects. The region needs standardized, factory-built housing models with pre-approved planning templates. If a design meets standard specifications, planning approval should be granted automatically within 30 days.
The Uncomfortable Truth
There is a catch to this contrarian approach, and politicians hate it.
Decoupling social housing from private development means accepting that the state must directly fund social housing through upfront taxation or long-term debt, rather than trying to squeeze it out of developer margins. It means admitting that land values in prime urban areas must fall if affordable housing is to exist there. It means telling homeowners that their property appreciation might stall because local supply is actually meeting demand.
Andy Burnham's current strategy relies on persuading a hostile market to perform a social good that runs counter to its financial survival. It makes for excellent political rhetoric, but it delivers very few keys to very few working-class families.
Stop asking if housebuilders can deliver political ambition. They can't, they won't, and economically, they shouldn't be expected to. Until local leadership accepts how development capital actually works, the housing crisis in Greater Manchester won't just persist—it will worsen.
