In recent years, the results of resilience research have been applied to the adaptive strategies of urban systems facing unpredictable risks, but the exploration of resilience in the field of urban and architectural design remains rare. Through analysing and synthesising research on flood resilience, this paper discusses practical methods of urban and architectural design in the context of flood resilience and develops a design framework from the perspective of engineering design. The specific operational steps are as follows: after vulnerability analysis of the target project, the components of the project are divided into three levels: planning pattern, architectural layout, and architectural details. These levels correspond to three design strategies: multidisciplinary decision-making based on GIS analysis, quantitative evaluation based on Grasshopper, and architecture optimisation guidance based on nature-based solutions. Finally, a case study of a Chinese campus shows that design optimisation based on a multi-level strategy improves the overall ability of the campus to deal with rain and flood disasters, and provides a reference for similar engineering practice. By proposing a general framework for urban and architectural design, this paper promotes the development of flood resilience in the field of applied engineering.
