Pics are in. I've tried to take photos from the start to now to give you an idea of how run down the back was. Seriously, it was almost at the point of getting a drip torch on to the bastard.
This is from the side gate looking towards the back.

Half way up the slab looking backwards
The concreter still has to come around and do some expansion cuts because there's a tree next door that will likely crack the slab if he doesn't. I might see if the owners can remove it, it's just some piece of **** thing that just drops leaves everywhere and clogs gutters. Now I just need to clean the beds out, remix have them and then next step is another coat of paint on the pergola and then redo the timber slats (if you look at the pics you can see where they've been removed from) and then it'll be time to get stuck into the top section over Christmas.
