Abstract

Many different words are used to describe what engineers and architects do when working on existing structures and buildings, whether of great heritage importance or notconservation, restoration, rehabilitation, refurbishment, renovation and repair, to name just six. There is much debate about what they all mean and, indeed, whether it really matters exactly what they mean-and this is surely a good theme for a briefing article in a future issue of Engineering History and Heritage.
