Tools you may need
- Shovel

Steps
- Mark the pad 12 in larger than the shed footprint on all sides.
- Excavate sod and soil to 4-6 in depth.
- Lay landscape fabric, then 3/4-in minus gravel in two compacted lifts.
- Screed dead level with a straightedge — shed doors judge your level.
- Set blocks or the shed per manufacturer's foundation spec.
Maintenance
Yearly: check for settling at corners, re-grade splash-out gravel, keep vegetation off the pad. (Suggested interval: every 1 year.)
