Wall cracks in 7 year old barn conversion

[Markyb250]

Hi all, I hope you are well. Just looking for anyone's opinion on these cracks.

Both cracks have been here since we moved in and after filling they have recently began to open again 18 months on.

The first crack is against the join in the wall and runs vertical up the wall between the join. It the part where the old stone building connects to the new brick part. The crack is straight but you can fit a 50p coin in between. I didn't know if this was just the join and the different materials reacting in the colder weather.

The second crack is in between two levels two steps high and has the shape shown in the image. It is a fine hairline crack but is quite long. Again not sure if this is the heat and cold or something else.

The exterior of the house looks fine with no cracks.

What do people think? Is this normal or should I investigate more?

Thanks in advance

I wouldn't worry about the vertical crack it will be expansion, the other could be a poor padstone detail. Unless bits of the plaster start crumbling then I would leave it alone for the time being.

Filled in cracks will always tend to re-crack.

They could have several causes, but would only be a concern if they continued to widen to several mm.
