Wall crack solution

[camerart]

Hi,
There a crack in the wall between the front room and the porch, which has taken 10 years to appear.

Outside there is evidence of crumbling bricks, so this is a consideration.

Above the proch is a window that was added, and I don't think it was done 100%, and maybe brick rubble fell into the cavity, not sure.

Looking at the front door, I can see movement over the years.

Is it possible to get some sort of repair estimate using photos?

Here's a photo from inside the front room, I can take more if needed.

If it's only cracked on the inside then probably just a decoration job.

Hi G,
It's more than that. As mentioned the front door has dropped.
Something has got to be done under the walls?
It probably too difficult for anyone to estimate, with photos, I just wanted some idea of what it may cost, without wasting a builders time.

Hi W,
Here, no sign in Porch, maybe only the inner wall skin?

Looks like a thermal crack not structural (foundation movement)

A door can't drop on its own as its connected to the frame. Has the frame moved on the hinge side? If that gap at the top is even all the way along then its not frame movement.

Hi W,
There's a gap at the right of the door, and rubbing also at the bottom.
So either this or this.

Hi,
I tried spirit levels, and it's hard to tell if #7 shows what's happening, but it looks like the top of the door has moved over a little and been decorated.

Outside, where the crumbling bricks are (underneath the bay window in the right of #1 picture) it looks like the bricks are shearing at the join, so it's pobably something at or below those bricks?
