How do I make a good base for a shed?
Get Local Building Dept. approval, they'll direct you on this as well. But, 4" of tamped sand only works if it's retained, it washes away. Tamped 3/4" jagged gravel at 4" deep is the best choice. The bigger issue is tying the building down from wind loft. This is where a concrete filled cinderblock &amp; poured concrete foundation may be required. Don't mess with the Town, they'll fine you $1000's &amp; also make you tear it down regardless of how right it's built.
