Core methods and guiding principles

• Start with a site audit: slope, soil, and existing utilities
• Size hardscape to the house and mature plantings
• Use verified, code‑compliant materials and fasteners
• Specify drainage layers and slope to a suitable outlet
• Plan for maintenance access and seasonal movement

These concepts are not tied to temporary design trends, which helps ensure that the guidance remains applicable across years and housing styles.

How to apply his advice to common homeowner projects

For homeowners, Roger’s approach translates into a repeatable workflow you can use whether you’re installing a small patio or regrading a yard.

Step‑by‑step checklist

1. Document the site: take photos, measure, and note sun patterns
2. Check local codes and permit requirements before buying materials
3. Define the problem first (drainage, wear, usability)
4. Size the project to fit your house and existing outdoor rooms
5. Choose materials rated for your climate and traffic loads
6. Install a stable base with correct slope and drainage
7. Plan for ongoing care: sealing, joint sand refresh, seasonal cleanup

If you follow this sequence, you’ll mirror the logic Roger uses on camera: diagnose, size, detail, then install. That reduces surprises and supports long‑term performance.
