I am converting our old garage into a home office. I am concerned about moisture from the cold concrete slab floor. The ceiling will be high, so raising the floor a little is okay. Floor moisture can be a problem.
First moisture can come up through the concrete.
Second, since the concrete stays cool, humidity in the indoor air may condense on the cold concrete slab. Seal the concrete with spray sealer. Cover it with 6-mil thick plastic sheets. Top the sleepers with subflooring and then the finished flooring.
