It is a common sentiment that concrete is the symbol and essence of materiality in architecture. For many designers the experience of concrete – the liquid stone – is the moment of getting the primeval insight into the nature of architecture and a confirmation that all that exists in the sphere of architecture has some form and matter. From this source spring the works of many an architect. In the following article three examples of Parisian architectural designs are presented, ones that have had influence over the development of ideas in modern architecture. Concrete buildings of Auguste Perret, Le Corbusier and the Beckmann N’Thépé atelier constitute the proof that confirms the thesis that some ideas remain, while others pass – the concrete matter, even though it is subjected to changes, has remained for a hundred years firmly united with the thought that brings the physical shape of architecture to fruition.
