Right, to try and answer some questions, apologies if I miss anyone out...
A few people have mentioned Google Street view, but it stops about 300 yards away, it really was impossible for a normal car to drive down (we tow about one lost idiot a month out!)
@AssassinatedBeauty not sure, could be buried in the puddle!
@TatianaLarina thanks! Didn't realise he was on there, this is definitely outing now to anyone that knows me!
@DeaflySilence thanks, they're very interesting!
@Purpleartichoke building is safe, it's a little way away and much higher
@ChardonnaysPrettySister definitely do not want it in the mail! I'm not good at sad face pictures... And the neighbors would take the piss for evermore 
@shouldwestayorshouldwego, nope, it's a back wall so no pictures
@SleepWarrior I'm pretty annoyed!
@TixieLix this is neighborhood rumour, so not 100% sure it's true, the access would be from their golf course, which backs onto the same muddy lane
@MinecraftMother don't worry, phoning them and asking them to fix it is going to be our first point of call! And are they in the Midlands area of the country at all?
We have legal cover, but will try through the council first, apparently they're open today according to the website, but I don't hold our much hope of hearing anything useful back from them today, but I will update with what they say later on.
