   I'd suggest, preferably, you bust out the old slab (if it's already broken up that probably means a poor base under the concrete). Rent a compactor to improve the base, pour a new slab with welded wire mesh to help keep the new slab from breaking up, then do the sleepers/plywood/carpet, or skip the sleepers and nail PT plywood directly to the concrete (with poly sheeting in between).

   OR use the existing concrete slab, shim sleepers level (again, poly underneath), attach PT plywood, carpet.

   Seems to me to be little advantage to pouring a new slab AND laying plywood. FWIW.

   *bust up the old slab... excavate.. put in a leveling course and compact... add two inches of EPS and pour your slab on top.. carpet the slab... or tile in the bath / kitchen areas...concrete slabs don't have to be cold...

   *I f your redoing the slab maybe consider radient heating. I don't know much about it but installation is supposed to be the big expense and since your there already it might really snug up the place.

   I have an old garage I want to turn into a cottage. The existing floor is an out-of-level, some-what broken concrete slab. My question is what is the best, most inexpensive method to install a new floor. I'm leaning towards a new level slab over the existing, then paper with CCA sleepers and 3/4 plywood for a sub-floor so the carpet won't be over cold cement. Any other suggestions?
