<p>This paper presents an in-depth exploration of architectural floor plan analysis through computational statistics, addressing the layout optimization and performance enhancement of buildings. Floor plans, which include elements like windows, walls, doors, and appliances, are pivotal for collaboration among architects, engineers, and clients, allowing for tailored designs based on client preferences. The study acknowledges the complexity and diversity of floor plans, which pose significant challenges for both human and machine recognition. Our research provides a thorough review of the evolution and current state of floor plan analysis, as well as a projection into its future. We systematically classify existing models into nine categories-dimensional, room-based, structural, retrieval, object-detection, graph, map, residential, and area-based-and assess them against criteria such as application domain, dataset, publication year, and reported performance metrics. The paper also discusses the practical implications of computational floor plan analysis, such as space optimization, energy efficiency, accessibility, safety, and comfort in the built environment. By processing and recognizing floor plan images, we can gain valuable insights and propose solutions to these issues. Our comprehensive review not only charts the progress in the field but also highlights the unresolved challenges and potential directions for future research. This includes the need for advanced models that can effectively process the intricate details of floor plans to further the goals of sustainable and functional architectural design.</p>
