Derlict Thursday: Edge of the abyss

There's a closed-down stonemason's yard a few streets away that I've had in mind as a fallback Derelict Thursday subject. I fell back on it today, only to discover that since the last time I passed it, the yard has not only been entirely cleared, there's now an enormous excavation in it!!

The only remaining part is this old shed, gamely clinging to the wall of the adjacent property.

This week's challenge is hosted by Himself  and freespiral. All entries can be found under the tag DerelictThursday.
