An isometric architectural illustration explains a five-stage modular building process: production in a factory, transportation by trucks, crane-assisted site assembly, module connection, and the completed building. The diagram includes modular wall sections, shipping containers, workers, cranes, trucks, and labeled stages arranged across a pale background with roads, trees, and green landscaping. Neutral tan, gray, and yellow tones create a clean technical style, while the final completed building features rooftop greenery, windows, walkways, benches, and planted surroundings.
