*France or Estonia* Is it possible to build a house on agriculture land/plot?

Hi everyone!
I'm new here and have one serious question to ask...

Me and my husband decide want to buy a land and do the permaculture in 2 years,

Now we live in Brittany, France but we consider go to live in Estonia.

We want to ask:
Is it possible we buy terrain agricole (agriculture land) and build a house on it in France or Estonia?
Does anyone did it legally ?

My French is very bad and I found this : https://www.service-permies.fr/particuliers/vosdroits/F924?fbclid=IwAR0traqazgXytlOs1ovrFCkk5h69vVzY5lS66Q8QL6vkc9HW6VWM1foru6k
But we are not farmers yet means that we can't build the house?



We heard some people said they have some of their friends before they buy the agriculture land,
they went to ask local city hall and mayor to see if they can build the house, mayor said if they have animals then they can build (so they bought the land, put 50 chickens and then they can build)
Wonder is this real??


Thank you in advanced!

I live in France, it's complicated, depends on the region as well. Depends on what you want to do. If you want to start a big farm like hectares i would think you're going to run into bureaucratic problems. Friends of mine bought land which was buildable (look for terrain constructible on le bon coin) and got a permit after paperwork  and have a strawbalevilla build on it in the middle of parc naturel Morvan. Others have bought a ruin and build a small strawbale house and are busy transforming a garden into a small farm. I have a house and work in the garden and the neighbor farmer saw that and now we have a project together. I know a couple which was looking for people to live on their super big land, i can ask if that's still happening if you like. Here you can make studios of 20 square meter without permit. The local government won't legalize you, because if they do you can demand of them they supply water and electricity. Costly stuff. If you're self sufficient and well behaved, which they will monitor (dreadlocks and dope they don't like) they'll let you be. Especially if you give wine and whisky to the mayor. I live in a village of nine, and am the youngest at 45.
Estonia, i don't know much about but that they are young dynamic modern and into making money. But i've not been.
