It is a curiosity to me too Barbara. I wonder (if at one time) there may have been an adjoining building sharing the protruding stones in the back wall and these simply have not been chipped away. I noticed the the masonry work was not as uniform as that on the front of the building and that parts of the chimney has been re-pointed.
My first impression was the same as the "happy snapper", but that doesn't seem practical.
I don't think so somehow Larry, because it is a much newer build than the house next door the other way.....it's also quite a steep drop at the side ....I will have to ask if ever I am walking past there....I am almost certain it's not to climb up to the roof :)). But then you never know round these parts ...!
it seems to be an elderly structure, the antennae sticking up on top looks forlorn. don't you love to be sitting in traffic and "see something"?! driving can be quite hazardous sometimes for that very reason! good you were stopped, i should try that more often haha.
I don't think it's as old as it may appear....and yes, there is plenty of opportunity to be sitting in traffic here at the moment, as almost every road seems to have road works with temporary traffic lights!!
