A PRESERVATION DISTRICT ZONING METHOD BASED ON TRADITIONAL BUILDING FORMS : Part 1 Zoning problems and indices for selecting discriminating traditional aspects

Abstract

This thesis consists of two parts. First, the concept of 'form purification' is introduced, based on a review of multiple meanings as well as the importance of the preservation district zoning. On this basis, the indices for discriminating traditional aspects are examined through a field survey in each of the following three preservation districts; Narai, Ohmi-hachiman and Takayama, Japan. The usefulness of the indices; 'wall finish', 'roof-material' and 'depth-height ratio of eaves' are verified. These form the basis of the 'form-purification indices'; their definition and usefulness are to be shown in the second part of our study.
