Dagmar Richter's work explores new solutions to architecture and planning by giving voice to elements deemed inappropriate or undesirable - traces of a site's history, contemporary photographs or drawings, and texts or spoken words. Richter's own work on "re-skinning" the city proposes that the act of designing is an act of editing, appropriating and layering. Her work, characterized by an absolute intensity of technical skill, addresses contemporary issues of authorship, precedence, site and memory. "XYZ" catalogues over 10 years of Richter's design practice. The book combines a descriptive, "hyper-linked" text arrangement with drawings, models and computer renderings of over 15 competition entries, urban design proposals and built projects.
