New neighbour using my private garden...

[Wattyyyy]

...

Would the builders not have asked them about planning permission before they started the work?

Oh my god this is unbelievable! What cheek!

Just when the CFN parking thread comes to an end, we have another CFN.

Placemarking (my placemarks are rare!)

Good grief! In my (misguided) belief that most people are pretty decent, I would say they have got their wires crossed, presumed the garden is shared and ploughed on ahead thinking all is ok.
I would go with the calm approach first and see what happens. Escalate to planning if they will not rectify their mistake. Good luck!

Just back from Googling 'giant Asda gnomes' and their website has crashed due to heavy load. Have you started a gnome-rush, InfiniteSheldon?

Agree with Judas you should speak to the builders, don't let them carry on. How DID the builders access your garden? The whole thing sounds nuts. I am surprised the builders did it tbh, it sounds like a strange design, is it a bit like a centre parcs lodge or something where part juts out? Was the window even legitimate in the first place?

Hopefully it's a massive misunderstanding on the neighbours part and not a deliberate attempt to be dicks

yes how did the builders get into the garden?

I second either a fence, or a wide flower bed right up to it.

Doesn't help in the short term though.

Definitely put a note through their door if they're not in & ask them to come to see you as soon as they get it.

How long have they lived there do you know?

Well it's obvious why they are installing doors, it's so they can access the giant trampoline and hot tub that's arriving tomorrow.

Goodness, OP! Hope you manage to sort this out.

Also agree with telling the builders to down tools immediately as they are working on private property without permission

I'm all for the fence but I'd be going nice and talk to maintain your privacy. I'm hoping they sort it out quickly op!

Agree with namechange. The builder, probably unwittingly, are there without permission.

Take plenty of photos OP

You just bought your flat - Is it possible your landlord knew about a planning application/permission and didn't disclose? It should have come up on your searches though so unlikely I suppose. Checking recent planning applications on your postcode should be quite easy to do online.

I'm not going to pretend to have anything useful to add. Placemarking.

And I hope it works out ok in the end OP.

Is there grass under the window? Make a border and fill with roses & gorse plants

Has the conservatory arrived yet?

Even if they are installing a juliet balcony / long window tha tcan't be opened into your garden, you need to go around NOW and tell the builders that they are not permitted to be in your garden and you will report them for trespass if they do not leave immediately.

Once they're gone, having secured their mess from the inside and removed every trace of rubble and dust from your garden, leave a photocopy of your land registry plan showing ownership of the garden for the neighbour and requiring (not asking or suggesting) that they immediately cease and desist from any activity on your land.

THEN - phone your local planning enforcement people - ours are amazing and shoudl be incredibly helpful.

In the meantime something very heavy against the doors, so they can't be used ?

That's awful! Does the door open inwards at all? If it does then perhaps they're planning on adding those little iron railings at the bottom like a mini balcony or something? Either way they're CF!!!

Make sure you get lots of photos OP!

We NED a highlighter'd diagram otherwise we cannot imagine the layout thanking you kindly what cheeky f*ckers!

Be nice when you go round , if they are U, then erect a massive block fence to stamp out any light/sunlight they may get

That is outrageous! Definitely put up a fence (or I like the giant gnomes suggestion!)
