What material is the office building in Quadrant 2 constructed from?

The office building in Quadrant 2 is constructed from reinforced masonry, which is a composite material that combines masonry—such as brick or block—with steel reinforcement. This method enhances the structural integrity, durability, and overall strength of the walls compared to traditional masonry alone. Reinforced masonry is often chosen for commercial office buildings because it can bear heavy loads, withstand lateral forces, and provide better fire resistance. Additionally, it offers excellent thermal and sound insulation properties, making it ideal for creating a comfortable work environment.

In contrast, the other materials listed may have their applications and advantages, but they do not carry the same attributes that reinforced masonry provides for large office structures. For example, wood is generally less durable and susceptible to decay over time, concrete, while strong, does not perform as well under tension without reinforcement, and steel, while very strong, would typically be used in different structural contexts or in combination with other materials rather than independently for walls.
