Next query for you guys who build decks?

I now have a sliding glass patio door to the outside. It's just mud right
now outside there and not much of a difference in level (3 inches maybe?).
Looking for something easy we can do ourselves. Is it possible to make a
low to the ground 'wood deck'? The ground has been completely termite
treated for sub-terranian termites but that would be a concern in our area
still.

What I do not want to do: pour a slab extension.

We've also considered just using paving stones (even the ground out first of
course) but a deck low to the ground would look nicer in this setting.
About 2ft out and L shaped with one leg 13ft and the other 11ft.
