Why is it important to use finishing materials in a designated area?

Using finishing materials in a designated area is important for ensuring consistency in design and quality throughout a space. This practice helps to maintain aesthetic coherence, as different materials can create visual dissonance if not thoughtfully coordinated. Additionally, it allows for better planning regarding durability and maintenance, ensuring that the materials used are suitable for the specific environment and usage. Lastly, it can enhance safety and functionality by adhering to building codes and regulations.
