New towns bring new responsibilities: Defining stewardship for Mixed Use developments from the start
By Gareth Bridgman
The UK’s renewed commitment to a new generation of towns marks a significant moment for the built environment sector. With seven large-scale developments proposed, it is positioned as the most ambitious housebuilding programme in over 50 years.
The projects signal a clear return to the strategic ambition of placemaking at scale. With each location to comprise tens of thousands of homes, the focus is rightly on the delivery of housing, infrastructure, and the creation of complete communities.
Yet alongside this renewed momentum sits a less defined, but equally critical question: how will these places be operated, managed and sustained over time?
Historically, the model was relatively clear and well understood. Developers delivered, and local authorities adopted key infrastructure embedding public realm, highways, open space into the civic fabric, funded through taxation.
Today, that pathway is less certain.
Local authorities are operating under significant pressure, and the widespread adoption of new assets is becoming less consistent. Responsibility for long-term management is increasingly sitting elsewhere.
Stewardship is no longer a downstream consideration
In the context of new towns, this role expands further. It is no longer simply about managing individual assets, it is the coordinated operation of interconnected systems of place, over significant timeframes and across multiple phases of delivery.
As responsibility shifts, clarity becomes critical.
Who maintains key infrastructure in the long term?
How are community assets operated and funded?
What governance structures ensure consistency across phases and over time?
And how are residents, occupiers and the community engaged in the ongoing life of a place?
These are questions that are fundamental to how successful places are created.
If addressed early with clear governance, funding strategies, and defined roles places are better positioned to thrive. Where they are not, complexity can build over time. We are already seeing this play out across large mixed-use schemes where stewardship has been addressed late in the process
The UK has a strong legacy of delivering new communities, particularly in the post-war era, but today’s context is different, places of this scale require considered approaches to long-term management.
What is emerging now is a range of models: private estate management companies, stewardship trusts, or hybrid structures, each with their own strengths and limitations.
Looking Ahead
The new town movement presents a significant opportunity to rethink how we approach not just the creation of places, but how they function over time through delivery and into ongoing lifecycle post completion.
Success will not be defined solely by what is built, but by how these places function, adapt, and endure. By placing estate management and stewardship at the heart of the conversation - and by addressing questions of responsibility early - we can create places that are not only delivered with ambition but sustained with intent.
The Role SAY Can Play
At SAY, we see this shift as an opportunity to bring greater clarity and stakeholder confidence to the way large-scale places are managed.
We have supported clients to help shape stewardship strategies that are practical, transparent, and aligned with the long-term vision of a place.
That means collaborating with the client and project team to:
Define clear operating models from the outset
Align estate management with placemaking objectives
Establish funding and governance structures that are robust over time
Support the transition from delivery into long-term operation
By doing so, we can help ensure that responsibility is not just assigned - but understood, resourced, and delivered effectively.
