Basic criteria of a good architecture: firmness, utility, and beauty have been inherited from the remote past. More criteria, which the environment built for quality and worthwhile life of man must fulfil, are derived from them and are defined by the Architectural Council of Europe in the book Architecture and Quality of Life. This contribution points to the risk of defining a good architecture. It is overestimation of its expression and underestimation of the general quality of the environment. It happens that attractively looking building with inhabitable interiors became examples of good architecture, which should be an inspiration for further projects. One of the examples of inappropriate decision of architecture is the family house in Stupava, where authors used for dwelling building a unconventional material – the profiled glass Copilit; they created a provoking but hardly habitable house. It was the consequence of using an intuitive method of design only without further experimenting and exact evaluation of the project. Architecture seems to be a substantial part of the environment; it becomes the ever more complex discipline. The conclusion is that interdisciplinary and holistic approach to both design and critique of architecture is inevitable.
