抄録

This paper intends to clarify block formation and building types of Pettah, Colombo, Sri Lanka, and then to analyze their transformation process. This is the part of the further studies based on the project called `Field Research on Origin, Transformation, Conversion and Conservation of Urban Space of Colonial Cities', whose major targets are Dutch colonial cities all over the world. Comparing spatial formation and transformation of the colonial cities in South Asia will be the next important milestone of the research. South Asia is the region where many colonial cities were built due to Dutch great efforts on developing the areas. Another purpose is to elucidate the Dutch way of houses construction in their colonial cities, e.g. Pettah, Dutch developed the form of town houses for high-density living. Colombo was once a head quarter of Ceylon, one of the five administrative districts laid by Dutch in South Asia. Pettah also played an important role as a commercial centre in British colonial period when the city experienced rapid growth. At present, a large part of town houses are reconstructed but street network, block formation and plots are still remaining. Based on field surveys, this paper focuses on Keiser Street, which is one of the main streets in Pettah, to clarify the transformation process of Dutch town houses to modern high-rise commercial buildings. This paper suggests that Dutch colonial town planning still plays an important role on the organization of spatial formation of Pettah.
