From land to keys: why housing delivery only works when the system does

The housing sector doesn’t lack land, capital or expertise. What it lacks is alignment, says EDAROTH programme director Toby Bonner. If we are serious about delivering social housing at scale, we must move beyond fragmented delivery and adopt integrated models that bring funding, land and delivery together from day one.

The housing sector is not short of ambition, nor is it short of land, capital or delivery expertise. Yet delivery continues to consistently and significantly fall short.

The uncomfortable truth is this: the problem is not the individual parts of the system, but a failure to align them.

Across the sector, landowners, planners, funders, developers and housing providers are all working hard, and in many cases working well. But they are not working together in a way that creates certainty, pace and accountability from inception through to occupation.

The result is a system that functions in fragments, rather than as a coherent whole, and if we are to move decisively from discussion to delivery, that has to change. 

Part of that change has to be the creation of long-term programmes that achieve investment and delivery predictability, which is at the heart of a sound business case for scalable businesses like EDAROTH that bring additive capacity to the sector

A system that works - just not together

 Over the years, each component of the housing system has evolved largely in isolation. Land ownership and control, planning, governance, grant funding, private finance — each has its own logic, its own pressures and its own constraints.

Individually, these parts can and do work. But they rarely work harmoniously. Housing associations, for example, are under immense pressure to manage and invest in existing stock, often limiting their ability to take on new development risk. Local authorities are balancing competing priorities with constrained resources. Funders are looking for clarity and certainty before committing capital. Planners are focused on the specifics of individual sites.

None of this is unreasonable. But collectively, it creates a system where bringing all the pieces together to move a scheme forward can feel “nigh on impossible”.

What is required now is a shift in mindset, from managing individual components to orchestrating the whole system.

What integration actually looks like

An integrated delivery model is often talked about, but less often defined. In practice, it is not a single intervention or reform but a way of working. At its core, integration means bringing together all the key elements of delivery from the very beginning:

• land ownership and control
• planning and governance
• public grant funding
• private and institutional investment
• delivery capability and resource
• and long-term ownership and operation

By contrast, an integrated model aligns these components from day one. It creates a shared understanding of risk, viability and outcomes across all partners, allowing decisions to be made faster and with greater confidence.
This is not theoretical. It is practical and increasingly necessary.

Funding: the importance of getting the structure right

A critical part of this integration is how we think about funding. There is a tendency in the sector to treat “funding” as a single concept. In reality, there is a fundamental distinction between short-term development finance and long-term investment capital and failing to recognise that distinction continues to undermine delivery.

Development finance is about enabling schemes to be built. Long-term investment is about owning and operating those homes over decades, often seeking stable, inflation-linked returns.

Both are essential. But they serve different purposes, carry different risk profiles and require different conditions to work effectively.

Encouragingly, there is growing investor appetite for long-term exposure to social housing. But that capital will only flow at scale if the underlying product is investable - high quality, durable and aligned with future standards.

For EDAROTH that’s about having the backing of global engineering services company AtkinsRéalis, and securing full BOPAS accreditation - including a landmark 100-year assessment for both our house and apartment systems. 

That means delivering homes that are not only viable today, but still performing decades into the future. Quality, longevity and certainty are not optional extras; they are prerequisites for unlocking institutional investment.

The role of the delivery integrator

If integration is the goal, the question becomes: who brings it together?
This is where the role of the delivery integrator becomes critical. Traditional development models often rely on a series of handovers between parties — landowners to developers, developers to contractors, contractors to operators. At each stage, information is lost, risk is reallocated and momentum can stall.

A delivery integrator takes a different approach. It works across the entire lifecycle of a scheme, connecting land, funding, design, delivery and long-term operation into a single, coordinated programme.

That includes:

• engaging early with landowners and promoters
• aligning with local authorities and housing providers
• structuring funding that blends grant, development finance and long-term investment
• delivering at pace through scalable, repeatable construction models
• and ensuring the end product meets the needs of long-term owners and residents

Done well, this approach reduces fragmentation, improves viability and accelerates delivery.

Why programme-based land assembly matters

 One of the most powerful tools within an integrated model is programme-based land assembly.

Across the country, there are countless small, often complex sites — garage blocks, infill plots, underused parcels of land — that are difficult to bring forward individually. On their own, they can be marginal, risky or simply unattractive to the market. But when aggregated into a programme, their potential changes fundamentally.

Bringing multiple sites together allows for:

• shared design and specification
• standardised procurement and contracting
• more efficient funding structures
• and the ability to scale delivery through modern methods of construction

In practical terms, it can turn a four-unit site into part of a 40-home programme, which is transformational for viability and impact. Importantly, aggregation does not remove the complexity of individual sites. But it does create a framework within which that complexity can be managed more effectively.

Creating the conditions for confidence

For integrated models to succeed, the conditions must be right for all partners to commit with confidence.

That means:

• clarity of pipeline, so organisations can invest in capacity
• certainty of funding, particularly around grant levels and long-term programmes
• quality and durability of product, to attract institutional capital
• and strong partnerships, built on shared objectives and trust

There are encouraging signs. The role of organisations such as Homes England, alongside new funding mechanisms and growing investor interest, is helping to bring these conversations together in a more coordinated way.

But conversation alone is not enough. The sector must now move to implementation.

From fragmented delivery to real impact

The ultimate test of any model is not how it looks on paper, but what it delivers on the ground.
Success is not simply more frameworks or more partnerships. It is more homes, delivered faster, at scale, and to a high standard. It is people living in those homes, and the tangible social impact that follows.

There is a growing recognition across the sector that the current, fragmented approach will not get us there. Equally, there is a growing sense of positivity that the tools, capital and expertise needed to do things differently are now in place. The opportunity is real. But it requires action. Integration is not a policy aspiration. It is a practical necessity.

If we can bring together land, funding and delivery into a single, aligned system—if we can move from isolated interventions to coordinated programmes—then we stand a genuine chance of making meaningful progress.

The journey from land to keys is not simple. But it is achievable. And if we get it right, we will not just build more homes—we will build a system capable of delivering them at the scale the country needs.
