Christoph Kro­n­hagel was born 1958 in Wolfs­burg (DE) stud­ied ar­chi­tec­ture at the RWTH Uni­ver­sity of Aachen from 1980-88. Dur­ing his stud­ies he de­vel­oped an in­ter­dis­ci­pli­nary way of work­ing that en­abled him to use all pos­si­bil­i­ties of vi­sual de­sign­ing. His am­bi­tion was to un­der­stand ar­chi­tec­ture as a medium for com­mu­ni­ca­tion: How is it pos­si­ble to re­flect so­cial con­di­tions in a way that the cit­i­zens will be pro­vided with a sen­sual ori­en­ta­tion? In 1991 the com­pany ag4 was es­tab­lished as a con­sor­tium for four di­men­sional con­struc­tions. Ag4 grew into an in­ter­dis­ci­pli­nary com­pany that cre­ates media ar­chi­tec­tural pro­jects which en­able com­pa­nies like, BMW, Aven­tis and Merck Serono, to com­mu­ni­cate their iden­tity in pub­lic space. The idea of trans­par­ent media façades was re­alised in 2004 when ag4 de­vel­oped the ap­pli­ca­tion of LED’s that made it pos­si­ble to de­sign and in­stall the first trans­par­ent media façade for the T-mo­bile com­pany in Bonn. In 2008, Christoph Kro­n­hagel left ag4 and es­tab­lished KRO­N­HAGEL ME­DI­A­TE­C­TURE GmbH in order to serve cus­tomers with holis­tic so­lu­tions for their me­di­a­te­c­tures in the fu­ture. In ad­di­tion to its for­ma­tive com­pe­ten­cies, strat­egy con­sult­ing, de­vel­op­ment and net­work­ing of me­di­a­te­c­ture with var­i­ous com­mu­ni­ca­tion chan­nels are among the range of ser­vices of­fered by Kro­n­hagel Me­di­a­te­c­ture – ser­vices which ar­chi­tects, com­pa­nies, urban plan­ners and in­vestors equally ben­e­fit from. As base for this work Christoph Kro­n­hagel pub­lished the book „Me­di­a­te­c­ture“, Springer NewYork 2010.
