Integration of environmental art design concepts for housing interior space design, improve space utilization, so that the interior space is effectively utilized to form a large space sensory experience. In order to enhance the effective integration of housing functional zoning and environmental art design in the interior design process, this paper proposes an interior design model based on BIM technology. The indoor floor plan design of housing is regarded as a multi-objective optimization problem through floor plan layout constraints, and the WFC algorithm is used to establish an adaptive evolutionary generation algorithm of indoor floor plan layout for floor plan layout solving. Based on the simulation and example verification, the time consumption of this paper’s algorithm grows slowly under the increasing sum of the number of rooms and design constraints, but the time consumption of this paper’s algorithm is about 87.5% compared with SAA algorithm after the sum exceeds 50. And the use of WFC algorithm can realize the generation of the floor plan layout of different housing types, and the user’s satisfaction with the functional zones such as dining room, master bedroom, kitchen, master bathroom and balcony is relatively good, and its score is between 0.65 and 1.0 points. Therefore, the application of BIM technology in interior design can effectively improve the efficiency of interior design, realize the effective integration of housing functional zoning and environmental art design, and fully satisfy the diversified needs of residents for housing functions.
