Looking for input from anyone who has built or does do the work. Very early stages of trying to find the least expensive option for getting a decent patio floor. In the area between the house and the deck you see in the picture below.

Data. The existing ground level pad is 16' x 15'. The house back door sill is about 8 or 9 inches above the slab. The deck on the other side of the area is about 12" above the existing slab.

I was thinking about laying treated 4x4's for a support structure and laying composite decking over that. But I'm reading that is not a good idea. There are termites. This is in Mississippi. Because of the limited height available, don't knw if a deck would work.

I did some preliminary looking at pouring a concrete slab, but I was getting prices around $6-$8 a sq foot. I want to do a deck/slab that is 16x25.

Any comments appreciated.
