Promoting the high-quality construction and high-quality development of housing has become the urgent demand of the housing industry, and providing quality housing that effectively meets the needs of users has also become the trend of the housing market. Based on the perspective of residential quality, this paper obtains 6 firstlevel evaluation indexes and 24 second-level indexes through the theory of the principle of construction of evaluation index system, thus composing the evaluation index system of residential quality of Hangzhou large flat project. Before constructing the evaluation model, we use hierarchical analysis method and entropy weighting method to calculate the comprehensive weights of evaluation indexes, and then combine the weights, topology method and cloud model to design the evaluation model of the living quality of Hangzhou large flat projects. Taking Hangzhou large flat project C as a research case, the model in this paper is used to evaluate and analyze it. After calculation, 24 secondary indicators show high living quality, with values ranging from 0.8 to 0.95, which concludes that the development direction of Hangzhou Grand Flat Project C is very suitable for the users’ living quality needs.
