If they coexist in the design process,what do they refer to and what do they stand out for? What kind of relationship can be established between the act of prefiguring the work and of putting it into operation,according to procedures and techniques that are coherent and necessary for its construction? The value of an architectural project is shown by its being a continuous search for expression of art,even if,as we know,architecture also has a social function and plays a civil role.The universal meanings and the cultural reference context,which have always been the heritage of the architectural project,are increasingly taking on a secondary value.Issues and concepts such as:tradition,memory,modernity,invention and location seem to have lost any research prerogative at the expense of the meaning and use attributed to the architectural and urban composition in the overall design process.展开更多
