Heritage restoration and listed building contractor
Est. 1991.
Some buildings have stood for centuries. We help make sure they stand for centuries more.
Historic buildings carry architectural character, communal memory and a sense of place that communities value deeply.
Restoring them properly requires a genuine understanding of conservation principles, close collaboration with conservation architects and Historic England, and a supply chain of specialist trade operatives who take real pride in their craft.
Sinden has been delivering heritage restoration and listed building refurbishment projects across London and the South East for over 30 years, including work on the Houses of Parliament .
We tell clients what these projects actually involve before they commit, and we back that up with a track record that speaks for itself.

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.
