L'orizzonte come limes-limen. Strategie compositive del Dom Narkomtjažproma di Ivan I'lic Leonidov

The contribution aims to investigate some interpretations that the theme of the horizon can offer to the discipline of architectural and urban composition. The intention is to decline the theme in geometric terms, reading the horizon as the apparent line perpendicular to the thing that are arranged on the ground. This condition is at the basis of some research in the figurative sphere that, by investigating the compositional potential of the horizontal plane, conceived it as the privileged place on which to obtain particular configurations given by the arrangement of certain objects on it. If in antiquity the experience of the Greek acropolis systems – in which, as in Athens for example, the presence of distinct buildings is absorbed by the great natural platform of the land that contains the spatial tension between them on a common horizontal surface – is paradigmatic for the explanation of this theme, in recent history is the Modern Movement that has taken up this principle through real paradigms of urban composition. It is precisely the work of Leonidov, which can be considered paradigmatic of ensemble composition, we would like to analyse some aspects.
