Urbanism defines a form of planning in which authors such as Rossi, Lynch and Escobar Wilson - White and Cardenas from their research and hypothesis, pose and agree that the city is determined by a series of behaviors and public and private spaces that make it to give a turn in its configuration, leading it to determine the meaning of its spatial structure in favor of a series of elements that agree with a particular feature that makes possible the change. Thus, from the central approach of Rossi in his book Architecture of the City, it is possible to have a basic point of reference that allows to give a substantial contribution to the conception of urbanism in the city. Likewise, the investigative sense of the way in which the city is configured is appropriate from Lynch's central hypothesis that is evoked in the book Ospinas 75 years, in which the constructor recounts how it is elaborated an urban projection, from 1932 to 1950 and from 1950 to 2008. based on the most interesting elements of architectural appreciation, which in the case of the town of Usaquen are defined in that transition generated from the hacienda towards the city. They deal with the perspectives offered from the European perspective of urban architects such as Brunner and LeCorbusier, and how a series of changes and transformations in the way of building and appropriating the city are generated in the midst of a sense of Modernism imported from a frilly European theory, which the authors recognize and develop, allowing them to trace the transformations that are lived in the city from the twentieth century, as Jacques Aprile-Gniset also shows in his text The Colombian Cities of the Twentieth Century.
