Wow amazing work everyone!! 
UPDATE
So I came back and obviously went straight in to the NSK shop to say thanks to lovely Ken and buy a bottle of red wine
And he gave me the wine for free! He says he feels sorry for me going through all of this and to enjoy the wine. He said I can let him know if I want him to KEEP WATCH again. I love him. I'm not sure when his shop closes, I think he just judges it on how busy he is, but I may be back over later.
However, he must have been serving a customer or some such because he missed someone/ something at the CFN flat.
I went and had a peek through their WHAT SHOULD BE WINDOW and there are a new set of patio doors leaning up against the kitchen sink unit. I can't really tell if they've done any work inside the flat.
There are also about 5 cigarette ends IN MY FUCKING GARDEN.
WHAT?????
So: either builders (COULD IT BE DIFFERENT BUILDERS?) have snuck in and are planning on replacing the doors with.... other doors? They are much nicer but still, it doesn't make any sense???
Or???
Anyone have any sane suggestion???
I feel like I'm living in some kind of parallel universe, where normality has just bypassed me.
What I'm seriously hoping is NOT the case is that they have been watching from somewhere waiting for me to go out.
