I am going to have a cabin/house in the forest measuring 8x5m.
I'm thinking of just building plyfa/cellplast/plyfa.
But I am a bit concerned about possible moisture from below.
How should I build to protect best? Suggestions?
Plastic, tape joints, frigg, plastic, plywood bottom?
Pillars/slabs or build on sleepers?
It should be simple and cheap. Last for 10 years... or more, but not more work for that.
Suggestions for protection? Paint with järnvitriol?
