The house was built 14 years ago using bricks; we recently purchased it.
About 4 years ago, a small brick wall was added. This wall was only plastered about six months ago.
Now, after a few cold days, cracks have appeared.
The wall stands on a concrete base, which was likely built together with the house and the rest of the terrace.

How should these cracks be repaired?
