Education estates are evolving rapidly, with the school rebuilding programme, expanding SEND provision and a growing focus on climate resilience placing more responsibility on estates teams than ever before.
Sinden has spent 30+ years delivering new build and refurbishment projects across primary, secondary, further education and SEND environments, working across London and the South East.
We work alongside the estates directors and business managers who depend on programme certainty and consistent delivery. And when programme or budget needs careful management, we say so early, when it still makes a difference.
