Architects do not actually build buildings, ' says Mikkel Frost, co-founder of Danish architecture firm CEBRA. 'What we build is an idea. To visualize it, we build drawings.' The evolutionary process of how aphorisms develop into precise architectural concepts is illustrated through a collection of Frost's sketches and watercolours. Over 200 drawings are organized into 20 sections, each relating to one of CEBRA's projects. An index containing c olour photographs and renders of their works further illuminates how the drawings are translated into reality. Introducing the book, a written version of Frost's TEDx talk Let your fingers do the talking elaborates on the book's impetus: to bring a spotlight to the craft of drawing as a powerful tool for creation and communication.
