I want to build a smaller semi-underground hut/house somewhere in the forest where I can spend a month or more alone. I will camoflage it as well and make it look natural.

I've read a few books and have a few years of carpentry experience.

I want it to be very hard to spot etc.

I'm from sweden, will I be completly fucked by angry landowners? I intend to build it very far away from civilzation but no doubt with modern technology etc you never know how much people know about their own land.

Is this feasable, or will it be impossible? Is it possible to keep the hut a secret? How do landowners usually respond?

I don't mind the morally ambigues part of it. What do you guys say?
