Conservation of Structure in Historic Buildings

Warren, John

This paper is based on the first of an annual series of lectures sponsored by the Alumni Association of the former Institute of Advanced Architectural Studies (IoAAS), now part of the Department of Archaeology, at the University of York in 2003. In the paper, presented as ‘Thoughts on the Conservation of Structure in Historic Buildings’, the author explores the view that structure is the essential component of buildings. Conservators have the options of structural repair, reinforcement, or replacement. The comparative ethics of these options are considered. The guiding principles are those adopted at the IoAAS, with a preference for repair of the existing structure and retention of function. Accurate diagnosis is essential. Respect for the tangible historic fabric controls decision-making. Reinforcement is acceptable, but must not be paraded. Replacement may mean substitution of an original structural system by an alternative structure, even where the fabric is retained. Ethical arguments may be complex, requiring clarity of thinking in relation to general principles and our own motivation. The interdependence of conservators and their mutuality are considered.
