BUILDINGS FOR HOUSING: STEEL TECHNOLOGIES IN THE TWENTIETH CENTURY.

In house architecture, the steel technologies use has constituted, specially in Italy, a research and experimentation field rather delimited. Although the house topic has been most important in the modernist discussion, becoming, after the war, a social problem, its declension as to steel technology remains conditioned by the historical events, the autarky, and cultural background doesn't accept the temporary idea of housing, suggested by use of steel. In the outlook of vicissitude with fragmentary border reconstruction, the goal is to research technical modes and building system and to assess technique and shape implications. These technical-project vicissitudes were analyzed as to different topic trends: "experimental house", "anti-seismic house", "temporary house" and "steel house". The building experiences of steel house have implied innovation processes, marginal and partial, and large and general tendency to technique hybridization, researching more the factors of constructive and functional rationalization, than the syntactic and linguistic potentialities.
