Between “limes” and “limen”Analyzing the gathered projects, there is a common result,characterized by the Latin words “limes” and “limen”. Thetwo words explain the way the projects, giving shape to theinterection between town and countryside, establish acondition of limit or threshold.01. The agricultural Gugliotta park at piano Tavola, CariniAt Carini, for the first area of the project there are two differentattitudes. The groups Cacciatore, Farina, Prandi andModuloquattro analyze via Rocco Chinnici as main elementof their intervention, while the groups Elmo and Trisciugliodesigned installations where this axis is diluted or denied.02. The margin of the agricultural park of stream SanVincenzo, that overlooks corso Italia at CariniThe future park is an extraordinary potentiality of the area ofthe project where there is the entrance. The group Ferromodifies the perimeter of the intervention including the area ofthe station. The group Fiamingo revises the curtain on corsoItalia constituing existing buildings and new architectures.The groups Gresleri, Saitta and Guaragna draw their attentionto the countryside near corso Italia, identifying a quadrangularperimeter of the area that changes, in the project by Marino,into a built in square.03. Transversal crossing torre dell'orsa-airport-main roadThe area of the project, near Falcone and Borsellino airport,leads the designers to analyze the relationship between theinfrastructures and the territory. The motorway, the main road,the railway and the underground cut the sprawl developed ona previously agricultural territory. The projects (Catarsi,Costanzo, Culotta, Falzetti, Sciascia), playing on the remainingcountryside, establish connections between the inner parts ofthe area and the external margins and the new Gesap area.04. Infrastructures, countryside and urban tissues atPartinico. Between the road ss113 and viale dei PlataniThe planned areas, as a substitute of the industrial installation,propose different types of interaction between built and thecountryside, considering the design of the new ring road and therelationship with the station. In the projects (Cannizzo-Davì-Gentile-Macaluso, Ferrari-Monestiroli-Tinazzi, Strappa, Trentin, Viola)central spaces come out and they mediate the close town,Partinico, with the agricultural expanses, open spaces in a stretchedinstallation that often follows the settlement features of Partinico.05. Continuity between urban tissues and agriculturalspaces at northern PartinicoIt is a field, not much definite by the urban feature, surrounded bythe countryside. None of the two parts can supply suresettlements. Their conditions drives the designers (Daidone, Giani,Menagatti-Nencini, Palma-Ravagnati, Stendardo) to consider theterritorial scale or the smallest paths inside the countryside.The proposals respect the hypothesis of the research, based on“Town in extension” by Samonà. So a rewriting of the projectinterventions allows, finally, to recompose the fragments of brokenup soils. The appropriation of the soil, as a place of living in thetown in extension, seems to be obtained by a part of the project(agricultural, urban and landscape project). Living has had thepossibility to define through the design of a limit or it has extendedthe threshold immoderately. We imagined a new unitary and inextension town for the five places, where the boundariescorrespond to the geographical ones and the urban feature of thesmaller centres and small buildings are evident thanks to thecomplementary action of the design of the countryside.
