Can I build a deck directly on the ground?

Yes, you can build a deck directly on the ground, but with some conditions. A deck on the ground must be built with ground-contact wood, and the substructure needs to be adapted for minimal height. Even though technically a ground level deck is elevated up to 24”, here we will discuss decks built less than 8” high.

How stable are floating decks?
