Hi I am soon going to be proceeding with fitting real wood flooring in my kitchen , the sub floor is a suspended floor of timber floor boards T &G , my question is would the best way to do this be to lift the existing floor boards and have the T&G solid oak flooring fitted directly over the joists . I am obviously giving consideration to the fact that if the new flooring is placed over the existing sub floor then it's going to mean an increase in floor level from hall to kitchen .. What's the usual way of doing this I'm wondering guys ? Any constructive advise very welcome please.
