    existing cellar, removed flags, and dug a further few inches
    Which would be better option?

    1) rubble first then put sand on top and level. Then put Visqueen Damp proof membrane 300MU black sheet, then kingspan insulation. On top of the kingspan insulation I then lay the T & G moisure resisitant chip board. Then finally finish with laminate flooring.

    OR

    2) put sand down then level it. Then put Visqueen Damp proof membrane 300MU black sheet, then put kingspan insulation on top. Then finish with 3" / 4" concrete.

    Best long term solution, Any downside with option 1. It will mostly be open space , I don't intend putting lots of stud partions, in which case I'd need a solid floor.
