'We are a forum for all professionals working in the field of architectural conservation. Our current membership of more than 350 includes architects, surveyors, engineers, conservators, scientists, archaeologists, building performance experts, historians, government advisors, property and estate managers, and many other professionals ... We do this by regular meetings, lectures and discussions, site visits, and once a year a conference covering a topic of special interest. Most lectures and meetings are held in London, but local meetings of the Association may be organised by convenors in other parts of the country ... Non Members are welcome.'
