About Sinden Construction
Sinden was founded in 1991 with a clear set of principles. That the best construction businesses are built on relationships as much as results, and that the buildings they deliver have a life far beyond the building contract.
Schools that shape young people, healthcare facilities that serve communities, heritage buildings that carry history forward, homes that people are proud to live in. We have always taken that responsibility seriously. And it shows in the quality of our work, and the clients who come back to us.

What that track record means in practice is a contractor with the knowledge, the accreditations and the supply chain to take on genuinely complex work, and a leadership team with the personal involvement to see it through properly.
We have worked across occupied hospitals, listed buildings, live education environments and high security sites. Each sector has taught us something that all future projects benefit from.
Our clients come to us because they want a contractor who will engage seriously with their project from the outset, give them a clear and honest picture of what delivery requires, and remain just as committed long after handover as they were on day one. Building that kind of trust, and sustaining it, is what we have always measured ourselves against.
That is the business we have built. And it is the business we are still building, with a growing presence across London and the South East, deeper roots in the sectors we know best, and a clear sense of where we are headed next.
At Sinden, how we work matters as much as what we deliver. These are the principles that guide every project, every relationship and every decision we make.
