The design concept of the residential isolation area and the design results are described in the report.At the beginning of the design, three schemes are prepared, and the most suitable scheme is selected through scheme demonstration. The most important advantage of the selected scheme is that the design is novel and meets the design requirements. The architectural design meets the following requirements: 1) meet the requirements of building function; 2) adopt reasonable technical measures; 3) consider the requirements of building aesthetics; 4) meet the requirements of overall planning. In the design of the plane function of the building to do a comprehensive analysis, in order to achieve the most reasonable space combination, to meet the requirements. This paper uses Tianzheng software to draw the plan, elevation and section of the building, and organically connects these aspects to establish the corresponding building model.
