Design a classroom building that follows the architectural principles of Le Corbusier, with a modern and clean structure, utilizing straight lines and geometric forms. The building should blend harmoniously with the surrounding natural environment. Incorporate ample green spaces with abundant vegetation, such as lush trees, shrubs, and gardens. Design pedestrian pathways that wind through the greenery with straight trajectories, creating clean and orderly visual lines. Depict people walking along the paths, enjoying the natural surroundings and accessing the building. The people should be in motion, creating a sense of vitality and dynamism. Pay attention to details such as natural lighting, cast shadows, and the texture of materials used in the building and pathways. Ensure that the design is functional and aesthetically pleasing, combining modern architecture with the natural environment in a balanced and harmonious manner.
