Renato De Fusco has repeatedly stated that interior architecture
does not exist. The essay briefly traces the development of this
idea, focusing on the theories that subsume De Fusco’s Storia
dell’arredamento (1985) and how the binomial envelope/enclosure, defined by him in the semiotic-structuralist vision of architecture, leaves no doubt to misunderstandings: furnishing concerns the faces of the enclosure, but with Le Corbusier it loses its
raison d’être, and from now on we will only speak of architecture
or design.
