By 1998 the total floor area of urban residential buildings was 9.59 billion square meters in China. In this period, most of the apartment buildings in China adopted brick-concrete structure or shear wall structure without SI-system, and limited the integrating means of retrofitting and reuse. Because of the strict control of area standard in urban residential construction at that time, the toilet area is always too small to carry the contemporary life style, which takes the first difficulty within independent retrofitting of the apartment building. Since the same-floor drainage system is widely used many new built apartment buildings, this paper aims to research and develop this system into retrofitting of the existing apartment buildings without S-I system in China. Based on the analysis to the household plans and their retrofitting design, two kinds of same-floor drainage systems are employed within the toilets, solve the problems of pipe connection, floor elevation and waterproof, and succeed to improve the function and space use of whole household.
