A research, presently in development, -work in progress-, referring to Architecture assumed as globalization tool, and affecting the Constructed Ambient by the presence of Global patterns, applies new instruments so as to frame and analyze Global forms and local transformation of the Constructed Ambient. Mercosur space is the focused area and such scale determines the application of digital methods to board the understanding of urban concentrations receiving architectural new patterns studied applying informatic tools. By other way, digital descriptions are used as the best choice for representing all this process -still unfinished-, which conclusions will be ready at the end of next year.
