Retrofitting inclusion: what the fabric of a building tells you first
by Samantha Smith
Director, Building Consultancy

I had the pleasure of speaking at the Education Estates SEND Conference alongside Sue Corbett from Star Academies and a fantastic group of fellow practitioners.
We were there to explore how mainstream schools can successfully integrate SEND provision and the conversation was honest, energetic and, given the government’s schools white paper landing just days later, very timely.
Much of the discussion centred on a challenge that I encounter regularly in practice: the gap between what a school needs to provide for its pupils with SEND, and what its existing building can realistically support. That gap is rarely just a design problem. Before you can think about what a school should become, you need a clear and honest understanding of what it currently is - structurally, physically and operationally. That is where building surveying comes in.
The live school challenge
One of the themes that resonated strongly during the conference was the challenge of working within live, operational schools. Retrofitting SEND provision is not something that can happen in an empty building over a long summer. It happens around children, staff, lessons, safeguarding protocols and the daily rhythms of a school that cannot (and should not) be significantly disrupted.
This is where careful phasing and sequencing becomes one of the most critical disciplines in the whole process. Getting it wrong is not just an inconvenience. It affects the wellbeing and learning of pupils, the confidence of staff and families and the trust that has been built through co-design and stakeholder engagement.
Good phasing is built on detailed knowledge of the building, how different areas relate to one another structurally and operationally, which works can run concurrently and which must be sequential, where temporary measures are needed to maintain safe and functional school operations throughout. It requires close, ongoing communication with the school, flexibility when the unexpected arises, and a level of practical site knowledge that only comes from experience of working within occupied education environments.
Exploring the live school challengeThe conversation at the conference reflected much of what we have been working through directly with Star Academies over a number of years. That ongoing relationship has given us a detailed understanding of the challenges that large, complex multi-phase school sites present when a Trust is trying to improve and expand SEND provision across its estate.
The picture is rarely straightforward. Sites that have grown and evolved over time carry accumulated constraints - structural, circulatory, safeguarding - that only become visible through rigorous assessment. The schools that need to change the most are often the ones where change is hardest to deliver, because the building itself has not been designed with flexibility in mind.
What our work with Star Academies has reinforced is how much depends on getting the foundations right before any commitment to a design direction is made. Understanding the existing fabric in detail, what it can support, where it is underperforming, how it is actually being used day to day, is what makes the difference between a solution that works and one that simply adds space without solving the underlying problem.
That preparatory work: the condition assessments, the structural analysis, the safeguarding and circulation mapping, the phasing strategy. This is where the real complexity sits. And it is the work that has to happen before a single brick is moved.
What good retrofitting looks like
We have developed a strong belief that the best retrofit outcomes come from treating the existing building as an asset to be understood and worked with — not an obstacle to be overcome.
The school estates that will respond most effectively to the government’s ambitions for inclusive mainstream provision are not necessarily those with the most capital to spend. They are the ones that start with the clearest picture of what they have, develop the most realistic plan for improving it, and deliver that plan in a way that keeps the school community at the centre throughout.
Rigorous assessment, intelligent retrofitting and carefully managed delivery - these are the things that turn ambition into environments where every child can genuinely thrive.

Frequently asked questions
Retrofitting inclusion means upgrading an existing school building (the current estate and fabric) so it can successfully integrate SEND provision in mainstream settings, rather than relying only on new-build solutions. In practice, this involves assessing how classrooms, support spaces, circulation routes, acoustics and safeguarding arrangements work today, then planning intelligent retrofit works that create environments where pupils with Special Educational Needs and Disabilities (SEND) can learn, regulate, and thrive without disrupting the wider school community.
The main challenge is delivering construction and improvement works in a live school environment, around pupils, staff, lessons, safeguarding procedures, and day-to-day operations. Retrofitting SEND provision usually cannot be completed in a single holiday window, so the project must be delivered with careful phasing and sequencing. Poor phasing can negatively impact pupil wellbeing, learning, and staff confidence. Effective planning depends on detailed knowledge of how the building functions operationally, where temporary arrangements are needed, and how to maintain safe access, circulation, and safeguarding throughout the works.
Good SEND retrofitting treats the existing school building as an asset to understand and work with, not an obstacle. Strong outcomes come from rigorous upfront work: condition assessments, structural analysis, circulation and safeguarding mapping, and a clear phasing strategy. For school estates, especially complex, multi-phase sites across a Trust, this approach helps ensure the retrofit does more than “add a room.” Instead, it delivers practical, inclusive learning environments aligned to government ambitions for inclusive mainstream education, while keeping the school community at the centre of planning and delivery.
