We bought newly built house about just over 5 years now (it's a semi detached). However, over time cracks developed in the corners of the walls - ground floor and the bedroom upstairs (the wall attached to another building only). We had attic done up not that long ago and showed it to the builders. They didn't express any concerns over it.
It's not a problem to just get some plastering work done and get the walls repainted (due already anyway), however, shall I be worried about it? In case there's is something structurally wrong with the building? I would much appreciate your thoughts.
