LiamSando, Hi.
Agree with last post, there could be a serious problem? But, some further images would assist?
Is the wall above the door lintel going up to a second story? or is there a sloping, or Duo-pitched roof resting on this area of wall?
If the wall continues upward above the Door lintel level, then there is a possibility of what is called "Lateral Restraint"
As above if the wall continues upwards? then wall tie failure can not be ruled out?
If there is a Duo-pitched roof over the problem could be so called "Roof Spread"
Another possible problem is that the lintel or the Lintel bearing may need to be looked at as a possible area of failure
Really need more external images if possible please? including any images of any internal damage.
Sorry if I am asking more questions than providing any sort of an answer, simply not enough digital imaging of the damaged areas.
Ken.
