What is NOT a characteristic of Niemeyer’s architecture?

Niemeyer's architecture is renowned for its emphasis on organic forms, fluid lines, and the integration of structures with their surroundings, showcasing a strong connection to the natural world. A defining characteristic of his work is the use of curved forms, which is evident in many of his iconic buildings. Furthermore, his designs often feature minimal load-bearing points, allowing for the creation of open spaces and free-form structures that invite natural light and air.

Sculptural concrete elements are another signature aspect of Niemeyer’s style, enabling buildings to take on dynamic and expressive shapes. Contrarily, strictly cubic designs do not align with Niemeyer’s aesthetic; his architecture reflects a departure from rigid, box-like forms in favor of more fluid and organic structures. Therefore, the focus on strictly cubic designs is not representative of Niemeyer’s architectural philosophy, making it the correct answer to the question.
