After further research I think that the only problem I'm likely to encounter is the feet of the cabinet punching through the floor boards because I have no way to find where the joists are. So I'll put down a base board of 18mm plywood directly onto the floor and fix adjustable feet to the bottom of the cabinet so I can level it again if there is any settlement over time.
