5. Key Considerations
- Paint Quality: Emulsion and weathercoat paints offer better ROI than distemper .

- Surface Prep: Power-washing exteriors adds NPR 5–10/sq.ft. but improves paint adhesion .
- Design Complexity: Neoclassical elements (e.g., cornices) increase labor and material costs by 15–25% .
6. Cost-Saving Tips
- Use local primers (NPR 284–486/liter) instead of imported brands .
- Opt for aluminum windows (NPR 500,000) over costlier UPVC (NPR 900,000) .
- Buy materials in bulk for discounts (e.g., Asian Paints offers 5–10% off for large orders) .
