Collection of architectural concept sketches _ 2017 Excerpts from my sketchbook no.1 + 2 + 3 "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." -https://www.designingbuildings.co.uk/wiki/Concept_drawing
