Abstract

The problem of aging historic urban cores that are part of our heritage, yet can hardly function in a modem environment, calls for a study of current approaches to regeneration of such areas.


The last thirty years have seen academic discussion as well as large-scale practical experiments, regarding urban intervention in these areas. The different angles of the problematic regeneration of historic sectors are apparent in the physical-morphological structure of the city.


Urban intervention necessitates city-scale perception of intervention as an integral part of the urban structure. The sectors that constitute the urban “puzzle” sometimes converge, boarder-lines are often crossed and “dialog" take place. The convergence - articulation between old and new tissues-result in questions as regards the physical nature of this convergence and the way tissues relate to each other.


The same questions are raised in both theoretical discussion of theoretical approaches, and in practical architectural work - the design of solutions. This research deals with characterization and classification of designed solutions and the study of theoretical approaches to intervention and articulation. Its main object is to form a framework for formal study of intervention and of areas where existing tissues meet with new urban construction.


The main body of this research is concerned with the formation of a model for characterizing, classifying and analyzing architectural precedents that deal with intervention. The model includes the development of analytical method ensuring optimal coverage of classification options, and an empirical part designed to examine applicability of theory and to demonstrate and revise the analytical side.


The analytical part of the model was constructed, considering three issues that pertain to the examination of the relation and relative proportions of two tissues: The first issue included a definition and characterization of urban tissue, the other issue includes discussion on urban intervention and its characteristics and the third topic consists of a discussion about articulation as part of the phenomenon of intervention.


This discussion about the tree topics have led to the definition of three major classification categories, three main “profiles”: the classification of the intervention zone, the classification of the Intervention Profiles and the classification of the Articulation Profiles. The three main profiles constitute the ‘Frame Profile” and provide an overall view of the sum of the characteristics of intervention.


The model was checked, demonstrated and revised through empirical study of competitions in the field of urban design that were concerned with urban intervention. The results contain classification of the Frame Profile of every solution and display a typology of articulation - a formal-morphological indication for each type of Articulation Profile. With the assistance of these classifications one can apprehend trends in urban intervention and the attachment of intervention and articulation.


The second part of the research is a conceptual examination of theoretical approaches to intervention and articulation. The research focuses on four main approaches belonging to the category that perceive the city as form. The analysis of approaches is meant to allow the comparison and contrasting of conceptual and practical sides, an important didactic tool.
