Exploration design on public and open space along the city wall based on typo - morphological research

Abstract

The city wall of Nanjing is not only related to the landscape and townscape as the unique monumental landmark and typological boundary but also an important activity place and open space for the residents’ daily life. Along the city wall in the inner south part of old Nanjing city, Hehuatang block has the richest architectural relics of the Ming and Qing dynasties and the most complete historical spatial layout and traditional house types. Taking Hehuatang as a case, this study aims to explore the design methods of public space and open space in the process of urban transition. Based on the methods of morphology and typology, this study sorts out the area structure, boundary, open space and architectural form through typological map information overlay and software simulation. The result has shown the regulation of transition in morphology which is responding to the change of households and lifestyles in time. It will provide a rational model for the organizational design of public space and open space in the urban regeneration of historical areas.
