understanding the construction, characteristics and significance of old buildings is the cornerstone of good conservation

understanding avoids the need for blind faith 'forewarned is forarmed'

‘old buildings cannot be treated as museum exhibits. They have to continue to earn their keep, so they must change and adapt in order to remain useful and of value to people. Conservation is about managing this change so as to protect what is important while allowing old buildings to adapt to new uses’ and changing demands and requirements.’

change is managed so interventions are the minimum necessary to sustain a building's condition and continued use

authenticity is core to our actions

interventions are designed to respect texture and patina and aim to be reversible and re-treatable so future generations can enjoy what we have enjoyed
