Why are buildings detailed the way they are? Why do architects and engineers seem to come to the same kind of solutions to their detailing problems? Are we satisfied with such a situation? With environmental concerns so high on designers agendas, the answer to this third question has to be no. Collectively architects, engineers and specifiers need to revisit how they detail the built environment, and address the most important and potentially difficult area of the joint between materials and components. In Principles of Architectural Detailing the authors question the way in which buildings are detailed and in particular challenge familiar joint solutions. They offer practical guidance and a number of tools to help the student of architectural detailing in the decision-making process. The emphasis throughout is on using knowledge of construction in a creative and productive way to contribute towards a built environment that enhances our well-being and which is also sustainable.
