 Cauchie and his wife wanted that the distinction between the main art forms (architecture, painting, sculpture) and the minor art forms (decorative arts) disappeared to become part of the global œuvre.In 1979, the saving of the Cauchie House led to the idea of using it to house an "Adventures of Tintin" museum in cooperation with their creator, Hergé.Symbolically, on Christmas Day, 1980, Hergé gave Dessicy his official agreement to the project.
