The book 'Demolished modified engandered' shows architecture models of 45 icons of modern Austrian architecture. The chosen buildings have all either been changed, destroyed or were never realised. The models do not aim at being a scaled down direct representation of the build spaces. Instead the models seek to show the core design ideas of the projects. Each model is accompanied by a short description of the project as well as the methods and materials used to create the model. This project was carried out at the Institute of Construction and Design Principles (KOEN) at the Technical University of Graz. The institute, which has its focus primarily on teaching architecture to first year students, was founded in 2013. The interrelationship between the design and construction aspects of architecture are an integral part of the institute's teaching principles as well as the focus of its research projects. Furthermore, the Institute is in charge of the faculties model building workshop and specialised courses within that field. This publication is part of an ongoing research project looking into the possibilities, as well as the relevance of model making within contemporary architectural practice and the teaching thereof.
