• Design theory and cognitive/representational methods shape architectural exploration, incorporating design patterns, sketching, and automation as central tools for generating and evaluating concepts across decades [7], [8], [9], [10], [11], [15], [18].

• Diagrammatic reasoning and visualization are core methodological tools for exploring design space, enabling multiple representations (diagrams, sketches, models) to inform decisions across theory and practice [1], [4], [11], [12], [13], [14], [17].

• Human-centered environmental concerns foreground climate, sustainability, and built-environment localization as design constraints and opportunities, integrating ecological and social factors into the design process [2], [13], [16], [19].

• Theoretical foundations and cross-domain integration link architecture theory with engineering, architectural science, and evaluative methods, offering models of architecture as system and artifact with appraisal and transition phenomena [1], [3], [5], [6], [7], [15], [20].
