Heritage restoration and listed building services
Est. 1991.
Restoring and refurbishing Grade I and Grade II listed buildings, including museums, cathedrals and theatres, with conservation at the heart of every project.
Sinden delivers restoration and refurbishment services across Grade I and Grade II listed buildings, Victorian and Georgian estates, churches, cathedrals and civic heritage buildings, working closely with conservation architects and Historic England.
Our approach is structured around a conserve-rather-than-replace philosophy, a specialist heritage supply chain and careful early risk identification, ensuring that every intervention respects the significance of the building and meets the standards conservation professionals expect.
Multiple award winning heritage projects delivered, including Gainsborough's House Museum, winner of the RIBA Building of the Year
Trusted on some of the UK's most sensitive and high profile heritage sites, including UK Parliament, a UNESCO World Heritage Site
A heritage restoration contractor with the specialist capability and conservation expertise to protect what matters most.
Combining specialist craft, conservation-led delivery and rigorous risk management on listed building and heritage restoration projects.
Specialist heritage supply chain
Our network of heritage trade operatives brings expertise in stonework restoration, masonry repair and period detailing, with the quality of finish and faithful craftsmanship worthy of a Grade I and Grade II listed building.
Conservation-led risk management
We engage early with conservation architects and Historic England to identify and manage risk before it affects programme, finding practical, fabric-sensitive solutions that keep projects on track.
Rigorous programme management in sensitive environments
Heritage restoration projects are often live, occupied or subject to complex access constraints. We plan and sequence every project around these realities, maintaining weathertightness, protecting historic fabric and keeping programmes moving.
A unique blend of heritage and complex structural expertise
When heritage projects bring complex structural challenges, our team finds the right solution. Whether that means working from above on a building too dangerous to enter, or engineering a way to support scaffolding where ground conditions won't allow it.

What our clients say about working with us
"The Cathedral remained open to the public for the duration of the works and the site team were well mannered and accommodating towards the Cathedral’s needs. Sinden’s site agent and wider management team worked closely and collaboratively with Simpson & Brown and the client throughout. Their attention to high quality finishing and client aftercare service has been warmly received and appreciated by both ourselves and the client team."
"Sinden have approached our work on the Brook Theatre with real care, intelligence and professionalism, fully understanding the responsibility that comes with a landmark building of this significance.
From the outset, they recognised that this project is not just a refurbishment, but the safeguarding of a much‑loved cultural home for Medway. Their team has worked collaboratively and confidently, always solutions‑focused and technically assured, while showing genuine sensitivity to the building’s heritage."
