A NEW MANIFOLD, the inaugural issue of SAC JOURNAL, addresses the increased specialisation and possible fragmentation of expertise within architecture. Whilst historically always an amalgam of numerous forms of input, architecture is currently facing the necessity to assimilate and process hitherto unprecedented amounts and rates of information flow. How can architecture relate to emerging forms of specialisation within the discipline - not the least in its pedagogy and academic programmes? SAC JOURNAL by the Städelschule Architecture Class - one of the most experimental and internationally renowned postgraduate courses in architecture in Europe - publishes essays and projects by invited national and international contributors, students and faculty. The Städelschule Architecture Class has been led by globally respected architects and teachers such as Günther Bock, Peter Cook and Enric Miralles. With Ben van Berkel as its current Dean, alongside the involvement of international scholars and architects such as Daniel Birnbaum, Beatriz Colomina, Mark Wigley and Johan Bettum, Städelschule Architecture Class is known for encompassing cutting-edge design and exciting investigations into the realm of contemporary architectural discourse.
