Architects' Data is an essential aid in the initial design and planning of a building project. Organised largely by building type (from airports to zoos), it covers user requirements, planning criteria, basic dimensions and considerations of function and siting. There are additional sections on building components, services and building physics, fire protection, and designing for the disabled. Most illustrations are dimensioned, and each building type includes plans, sections, site layouts and design details. There is a detailed set of metric/imperial conversion units and an extensive bibliography.
