Lexicon N°1: The succeeding pages are the result of a seminar taught at the Berlage in the autumn of 2015 by Tom Avermaete, Proffesor of Architecture, and Hans Teerds of the TU Delft's Chair of Methods and Analysis. Students sought new insights on the relationships of architecture to society by identifying forty-two keywords based on recent perspectives on how architects practice today. Accompanying this nomenclature are ten critical positions on the changing role of the architect.00Lexicon N°2: Originating as a preassignment to the Ben van Berkel-led design master class entitled "Architecture without Architects/Architecture without Architects?", held at the Berlage in November 2014, this book is an attempt at dialogue and debate on the changing role of the architect. Tom Avermaete and Hans Teerds of the TU Delft's Chair of Methods and Analysis, along with myself, selected a number of keywords focused on the evolvoing defenitions and positions of the architect both within the boarder context of society. From this point of departure, nine Berlage students articulated their own terminology to meet challenges related to the contemporary built environment. The result is an indexical reflection-written in their own voice-of how this group of young architects would like to practice today.
