Concept drawings or sketches are drawings, often freehand, that are used by designers such as architects, engineers and interior designers as a quick and simple way of exploring initial ideas for designs.
They are not intended to be accurate or definitive, merely a way of investigating and communicating design principles and aesthetic concepts. Concept drawings can also be used to explore more technical aspects of a design, providing an initial response and possible solutions to problems, constraints and opportunities such as services layout, structure, method of construction, solar paths and shading, prevailing wind, patterns of circulation, relationships between aspects of the site and so on.
