Building Mass Analysis

Based on the provided architectural images, generate a clear set of architectural volume generation process analysis diagrams. It begins with a simplified initial overall volume, representing the building's total footprint and height. The volume is then evolved step-by-step: including initial volume division, height reduction, subtractive cutting of the volume (forming atriums or voids), and detailed derivation of the final form. Each step is presented as an independent axonometric block diagram, arranged in a logical order, clearly demonstrating the evolution from abstract volume to the final architectural form. The overall image uses a white or light-colored background, with restrained colors, downplaying the expression of realistic materials, emphasizing volumetric relationships and design logic rather than realistic effects.
