How to keep the floors warm in a wooden house without insulation?

Beam house with natural moisture (winter wood), 300 mm thick strip foundation.

From the floor to the residue 400 (approximately). I do not want to insulate the floor, I just want a basement and boards. Well, of course, on the boards to plywood and laminate on top. What can be done so that the floor in this form is not completely cold? Help insulate the foundation, blind area, expanded clay on the floor under the floor? What other options are there?

• insulation
