The Pocess of the Project by Marcello Piacentini Object to the City: Clariy and Expression for Wise and Balanced use of Proportions.

The harmony of the invisible architecture of Piacentini, indicate, in the facades of his main works, details of plastic resulting thickness of the walls with altered geometry and modulated surface.The articulation of the various projects is always controlled by the rules of proportion between full and empty, indicating a relationship with the modules and submultiples with evidence in detail of construction and the continual comparison with the carrier. These works lead to an overall effect that tends to bring out the details and the signs of Appeals as a element of modular measurement. This assembly determines, in effect, decorative elements derived from the modular size of materials, which are expressed with mathematical rigor, leading to a shift from general to specific to the geometric logic of the organic project. The Piacentini has expressed his own work on architectures for social shaping public spaces and / or relational spaces, consisting of a multiplicity of urban elements with a strong relationship between the shape of the history and structure of the city. For Piacentini was of primary importance in urban redesign projects, to defend the town center, enhancing the city's identity, preserving as much as possible the diversity of activities of the place. The research aims to identify and enhance, through specific aspects, achievements and entries in relation spaces, in the architecture of Piacentini, clarifying, models, values and functions that he intended to express in his long and varied production of works architecture. This search leads to highlight a fundamental element, which the study design and analysis of extremely complex processes, including the approach, method and procedure for the success of these works with unique characteristics, with a harmonious relationship between mathematics and geometry.
