ᐅ How to construct the floor assembly in a clay house on the ground floor?

AzureusHello dear building experts,
Our best friends have purchased a plot with an old clay house. So far so good, but unfortunately, they have many ideas and no real knowledge.
Now my question:
In one room of the house (ground floor – no basement), the beams and floorboards were rotten.
So they removed everything.
Now there is only soil as the base.
The house, like most houses, is built on large fieldstones.
How should we construct the floor assembly?
My ideas:
1. Level the ground, add gravel and compact it, then lay roofing felt with a 10cm (4 inch) overlap up to the finished floor level, then pour concrete on top.
2. Level the ground, roofing felt as in point 1, place wooden blocks, adjust them, put beams on top, install insulation wool (e.g., Knauf insulation), and then screw planed floorboards on top.
I would be very grateful if you could clarify this for me. Also, our friends have a limited budget.
Thank you very much in advance.
Best regards,
Holger

Roofing felt, as the name suggests, is not meant for flooring. Using it as a waterproofing layer under concrete and screed is unsuitable for several reasons and will likely bring construction damage—and thus unnecessary costs—straight into your new home.
You should not expect a free, ready-made installation recommendation for a complex situation like this from a public forum. A responsible respondent will first want to assess the site conditions, considering factors such as buildup heights, waterproofing options, and thermal insulation.
No, such complex matters must be handled and answered by professionals who truly understand them.
After all, it is pointless to simply adopt an idea presented online—nodding along and putting it into practice—if it doesn’t work, leaving you as the affected party alone with a failed attempt and the resulting damage.
