Transformation of Residential Units into Commercial Spaces in the Central Business District of Dar es Salaam, Tanzania

Abstract

This study aims to clarify the relationship that existed between traditional building functions and building components as well as to explain the way the change of building function relates to new space uses in the Kariakoo area. Firstly, the study reviewes the original architectural features, layouts, and meanings, of the Swahili/local architecture of the residential units which existed in the study area before their transformation. Secondly, changes in building functions are analyzed in the current situation while new architectural features and space uses caused by transforming residential units into commercial spaces were identified. Based on building components such as floor, façades, verandah, and roof, the study concludes typologies of new space uses obtained to facilitate the current commercial activities. Finally, the study observed that the change of building functions in Kariakoo has not only affected the building components but also that it has positively transformed the area in being place for both a living (residential) and working place (commercial) thus making Kariakoo an important hub in the city center.
