I want to build an 12x16 deck on top of an 8x10 slab. Slab is in good

condition. I want to lay the floor boards across the slab. I was
going to build a frame ( with2x6's) that would be on top of the ground
and in some areas partially underground to attach the floor boards too
where the wood deck would overhang the slab. Is this real for me to
do? Would the whole deck be able to withstand freezing? Should the
support beams in and on the ground be cemented or supported with stone.
I don't want any railing since I planning on building a pergola above
it in the spring? Kentucky winter?
