Thank you for the suggestions. At this point, I guess tamping it down and using a large bamboo mat to sit on will be the easiest and certainly cheapest option. Later on, if I decide to extend my stay beyond the planed 3 months something more sophisticated might be applied.
A window has been installed in the wall to the left. It will still be hot and humid but not more than outside. It is rainy season and everything is anyway very moist. Yet, when we visited the building for the first time it had already rained quite some and the building was at that point completely overgrown with creepers yet the floor inside was dry. I think leaving the green cover on the building will regulate the temperature on sunny days.
My questions:
1. The creepers will in a few weeks time seal the entire building again from the outside. How would you handle the growth?
2. How would that work with the linseed/ flax oil? Just tampering the floor and then applying the oil? Or do I need to create another surface that hardens naturally onto which i can apply it?
It seems that the locals were not concerned about snakes. I might anyway make some kind of barrier that will prevent any surprises
