Such conditions also reflect the fact that the inhabitants have their own opinions on the space requirements and thereby often require for changes. The main purpose of this research is to understand the development and the reconstruction problem of the townhouses in Taichung City and to study & analyze such problems as construction techniques, interface integrations and the effect of reconstruction upon original structure. Initially, this research uses the method of literature reviews and data collections to compile the data about the demand of housing market and to analyze the reason for reconstruction. Next, this research uses the questionnaire to look into the reconstruction space & category and its interface joint method, the after-construction influence upon original structure, and the follow-up use & repair in the practical cases. From the statistically analytic result of 40 copies of questionnaires, we can understand the current reconstruction condition in Taichung area. In Taichung City, most of townhouses are mainly scattered in Beitun District and secondly in Xitun District. From the questionnaire result, this research shows that the most frequent reconstruction area for these townhouses in Taichung City is balcony, about 72.5% of all questionnaires. Besides, most of joints between reconstruction regions and original structures are made by embedding the reinforcing steel bar, about 52%. As to the effect of reconstruction upon the building in the case of leaking or seepage, it is 83.8% and8.1% respectively (totally 91.1%) for “a part or parts of cases with some leakage or seepage conditions” and “all of cases with leakage or seepage conditions” and it is 8.1% for those without any leakage or seepage condition.For the reconstructed building with leakage or seepage conditions, the “high-elastic waterproof coating” is a common repair method and the “silicon sealant” is a general repair method. In conclusion, we expect this research could be a reference for all related industries through our analysis and survey on those townhouses with reconstruction conditions in Taichung City.
