I think there's been many a builder called out by over enthusiastic DIY shovellers! (and cowboy builders)
I and a builder did a one a while ago and (luckily) the exterior walls went down far below our excavations,but what i,m finding a lot lately is where home owners have had new upvc windows installed the window companies have not installed lintels,and over time the actual brickwork presses down on the new windows and buckles them leaving them unable to open,and in severe cases leads to collapsing brickwork,incidentaly i replaced 2 lintels a couple of weeks ago,which were steel which had rusted and expanded cracking a large area of brickwork above the lintels,the woman tenant was nearly in tears when i first inspected it thinking the whole house was due to collapse ! 
We are many,They are few
