An interview with Jonathan Sergison is published in a German language book on proportion and perception in architecture and urban planning

Proportion systems have been the basis of design since ancient times. But what exactly is meant by proportions: an objectively applicable system of dimensions and relationships, or a subjective and personal feeling? An interview with Jonathan Sergison is one of a number of contributions to the debate by practitioners and theorists that provide an overview of the origin of proportions, their theoretical foundations and practical application.
