Under the continuous improvement of people’s demand for quality of life and personalization, creative and functionally adapted housing design concepts are more and more sought after by people. In this study, the Prim algorithm is used to analyze the house types and space planes in the housing construction project, and the creative design of the housing construction plane images in Grasshopper platform to get the draft graphic ideas of housing plane design. Then combined with the combination of spatial function module unit optimization scheme proposed based on housing architecture decorative art graphic design creativity and spatial function coupling scheme. The results of the case study of the housing architecture project found that the housing space program after the graphic and spatial coupling design was recognized by the tenants in terms of spatial creativity and functionality. The average satisfaction of tenants with the housing design program increased from 22.18% under the existing design program to 75.80%. This paper demonstrates the feasibility of graphic and spatial-functional coupling design based on the decorative art of housing architecture through examples, and lays the foundation for the coordinated development of artistic creativity and spatial-functional adaptability of housing design in the future.
