3. **Evaluate Durability and Maintenance:** Choose materials that are long-lasting and easy to maintain, especially for high-use areas.
4. **Sustainability:** Consider eco-friendly materials and energy-efficient options.
5. **Performance Factors:** Assess properties like soundproofing, thermal insulation, and light reflectivity.
6. **Budget Considerations:** Balance quality with cost, including installation fees.
7. **Sample Testing:** Test material samples in the actual space to assess appearance, feel, and performance.
8. **Supplier and Manufacturer Coordination:** Ensure material availability, quality, and delivery timelines.
9. **Final Selection and Approval:** Present the options to the client and finalize based on preferences and practical requirements.

This process ensures the materials chosen are not only visually appealing but also meet the functional, durability, and environmental needs of the space.
