This thesis attempts to address the problem within heritage areas that has arisen as a result of the widespread municipal amalgamations across Victoria over recent months. The problem is one of inconsistency in the heritage quality of buildings that come under heritage control. This inconsistency occurs when local government boundaries are altered so that two areas, formerly under the control of two different local governments, are joined to be administered by the same municipality. A situation is therefore created whereby different urban conservation zones within the same local government area have been established at various times, for different reasons, and as a result of contrasting conservation studies. Taking Ascot Vale and Flemington as an example of a heritage area where these inconsistencies have surfaced as a result of a municipal boundary change, this problem has been tackled by following a systematic methodology. After a visual survey of the area, detailed identification forms, notes and maps were completed, while photographs were taken of the built form. From this research, statements of significance were drafted. Based on these statements, suggestions were made to extend current urban conservation zones and to create new zones so as to include significant precincts outside existing zones.
