I removed an inbuilt cupboard and underneath was this mess. I need to make the floor good (level and remove shit laid different tiles) to lay another floor (in 2-3 years so short term fix needs be ok). I'm thinking just a sand cement mix to fill void, it's about 1cm deep. I have some of the same parquet tiles but limited supply so laying them a bit pointless.

Anyone got a better idea?
