dECOi, which was founded in Paris in 1991, describes itself as a research group encouraging project cooperation between architects and specialists from disciplines outside architecture. Nowadays, dECOi is operating at an international level in the form of an enlarged network within which mathematicians, computer programmers and engineers all take part in one and the same type of formal research. In addition to exhibitions, such as the Venice Biennale and more recently at the FRAC Centre in Orleans, Mark Goulthorpe is currently teaching at the Ecole Spéciale d'Architecture in Paris, as well as at Llubljana University in Slovenia. The year 2001 will see the installation, on the façade of the Birmingham Theatre, of "Aegis Hyposurface", a reactive architectural surface with metal facets which will be deformed by stimulae caused by the environment. For dECOi, new design and production procedures have radically altered architecture. The extension of the Dietrich House thus makes the most of all the creative possibilities of generative processes. It is hallmarked by a series of deformations of flat surfaces, which are rational in their functional use, but seem irrational in their architectural expression. The architect no longer determines a form of architecture, but rather creates a physiognomy capable of constantly evolving on the basis of multiple varying parameters.	(F)
