Revised Answer (140 words): In the lecture, the professor discusses the change in the design of tall buildings from the past to present. In the past, architects used stone to support the top of buildings. As a result, the stone walls were thick, thus limiting the available space inside. The limited space made rooms very small. However, nowadays, architects tend to use steel, which is strong and light, allowing for thinner walls and more spacious interiors. This shift in materials and design has significantly improved the functionality and aesthetics of tall buildings, providing larger spaces for various purposes. Overall, the evolution of building design has been driven by advances in materials and construction techniques, resulting in more efficient and visually appealing structures.
