Wattle and daub house advice needed

Hello Everyone!

Our family recently viewed a house that is supposedly built out of  wattle and daub. What we lack, though, is some experience to tell if there are problems to consider, so I was wondering if anyone could help. The idea is to use a natural plaster on the outside anyway, but we just would like to make sure it's worth getting it.

I attached two pictures that are concerning. One with weeds growing underneath and two anothers with discoloration on the exterior wall.

Any input would be greatly appreciated! Thank you in advance!

Can you see if that layer has cement in it?
Cement ruins wattle and daub because it interferes with the movement of moisture, causing damage.
Discolouration is not an issue, when you mix batches mistakes occur.

What is the climate where this house is located?
Does water have the ability to drain away from the house?

Thank you for your reply!

The house is located in 8a/8b zone in the southern France.

This house has a few drainage gutters.

While visiting the house we couldn't see the foundation and the agency isn't aware of what it could be. And we wouldn't be able to tell if there is any cement involved. However, garage that is adjacent to the house has a concrete floor.

Also this house was built in 2006, so I guess any issues would be apparent at this point? or not necessarily?

Well there is nothing wrong with concrete foundations.
What makes you think its wattle and daub, I think it may be rendered blocks.

Well, it turns out they've used clay bricks and covered them with a mixture of clay/straw or something.

There are products about that can replicate a similar colour and surface.
They may have been used.

Will you be buying it anyway?

No, we'll leave this one, as it might have more issues hidden inside than we would like to deal with...
