Piazza San Michele is located in a densely populated low-income fringe area of the city of Cagliari. Even in its decayed conditions, it was used by the population especially as a spontaneous street market.
The project was based on the analysis of the geometric, spatial and architectural components that characterized the exisiting urban space. The design choices were inspired by the following general criteria:
recognizability of urban space; flexibility of use in order to return the square to public use at different times of day and in various seasons of the year; safeguarding the exisiting green areas; maintenance of existing trees; use of resistant and durable materials and equipment requiring little maintenance; suitability of paved surfaces for different uses and stresses, regardless of prohibitions and impediments; choice of materials and processes that do not involve the consumption of non-renewable raw materials.
The new design for Piazza San Michele was based on the key geometric and spatial components that characterize the urban space, in particular the axes of the original route of Via Abruzzi, which crossed the square until the '70s, and the church as well as the area defined by the tree canopies. The main axes cross the oval of the urban space creating the main accesses that identify the green areas that surround the square. In front of the church the oval generates a series of slightly curved walls that redefine the relationship between the square and the church entry on a higher level.
The result is a strongly characterized design capable of reorganizing the various elements in a unified way used and respected by the local resident population.
