Architectural ontogeny and phylogeny of the “urban vertebra” It is interesting to notice, by analyzing the plan developed by Sergio Lenci for the project for which he has participated for the "ISES" competition for Low-Income Housing in 1965 (in conjunction with Alfred Lambertucci who handled the dwelling types), the presence of a premonitory symptom of the same "urban scale architecture" that Pietro Barucci had the opportunity and the ability to synthesize and systematize.

It consists of a perforated "plateau" that passes on top of the road, making the whole project become an “urban architectural device.” This generates a “city effect” that is totally in line with what was later built on a larger scale in the Laurentino 38 housing district.

Abstract

Architectural ontogeny and phylogeny of the “urban vertebra” It is interesting to notice, by analyzing the plan developed by Sergio Lenci for the project for which he has participated for the "ISES" competition for Low-Income Housing in 1965 (in conjunction with Alfred Lambertucci who handled the dwelling types), the presence of a premonitory symptom of the same "urban scale architecture" that Pietro Barucci had the opportunity and the ability to synthesize and systematize. A careful study of that project reveals that the above-mentioned site plan already contained almost all the elements of the insula of Laurentino 38, i.e. the bridge, lines, towers, and a two-level system for vehicular and pedestrian traffic circulation. In reality, with this design, the bridge is not an "equipped" one. It consists of a perforated "plateau" that passes on top of the road, making the whole project become an “urban architectural device.” This generates a “city effect” that is totally in line with what was later built on a larger scale in the Laurentino 38 housing district. It should be said immediately, however, that from 1959 to 1962 Pietro Barucci undertook, on behalf of the Roman Institute “Beni Stabili,” three phases of design. The first one was developed with Manfredi Nicoletti, immediately after the completion of the Mixed-Use-Development known as “Piazzale del Caravaggio” in Rome. This project, much admired by Leonardo Benevolent, would offer many sources of inspiration to the architectural design community and certainly also to Sergio Lenci, as it emerged from the proposal he entered several years later into the "ISES" competition. The "plateau" built in Piazzale del Caravaggio and the proposal of the Mixed-Use-Development in Turin of 1962, aim to create a piece of stratified city.
