To deny neighbour access to render extension?

A party wall award would almost certainly not have been required. There’s no reason why the extension’s foundations would have needed to be deeper than those of the original semi, so the 3m rule isn’t relevant.

There is no ‘right of light’ anymore. However, council planning would have taken all of this into account when assessing the plans and onsite visit before hand. There is a mathematical degree of light you must allow, the planner will measure this .. they did with ours recently.

If people want cooperation from their neighbours they should probably stop and think before building selfishly designed extensions

No she doesn’t.

Weird how they didn't worry whether op might do that before they built a hulking great extension though.

You can say no, but I’d keep in mind future consequences. If I was in their position and you said no, I’d probably spend the rest of my time living there engaging in petty revenge. Calling the council at any hint of noise, reporting any issue I could possibly find etc

Good luck op!

What type of goodwill could most people possibly need from someone who build away from the boundary with no notice, their builders climbing over the fence no permission and then wants to be cheeky enough to ask to move ops stuff to render their own extension.

Pretty much zero id say.

Ridiculous. Just hope you never need any cooperation from your neighbours if that’s how you behave.

As usual, first post nails it.

If you’re able Invest in mounted cameras at various points (indoor through windows so they can’t easily cover them) or not obviously placed, along with regular photos.
and reply ‘with as there’s no legal party wall agreement, I’m going to have decline (Prefably in writing ie email/txt so they can’t deny receiving it, reaffirming any verbal discussions as an audit trail (as they sound like they don’t care whether you agree or not)
ensure your access is locked and the cameras are on recording incase they try and access by climbing your fence/damage your property/trespass & deny your quiet enjoyment & safety for your kids/pets/you/property
dont feel bad ..they won’t!

Then they’re incredibly stupid - trying to save a penny and cost themselves a whole lot. Speak to your home insurance and check the position on legal fees as per your policy. They need a party wall agreement AND if any of your windows / garden are now blocked a right to light agreement. You have them over a barrel as they will be in breach of any funding taken out if you’ve not been consulted and consented - it could invalidate their mortgage.

If it blocks light then you can take it to court. There have been many MANY cases where parties building without consideration to their neighbours right to light have had instructions to take their developments down down. Their mortgage provider and insurer will be VERY interested that they don’t have agreement to block light. You also don’t have a party wall agreement which they also need to dig that close to your foundations. Those are not excluded just because it’s permitted development (it’s not permission to be a nightmare!!) Seek legal advice immediately. You do not want to be seen to be consenting to this, particularly when digging foundations to close to your own house could cause damage if done badly - you need proper consultation on this. You have grounds to sue.

It could all end up very messy...

I would tell them you would allow the work to go ahead. But only on your terms.

Get a letter or short contract drawn up by your Solicitor with the main facts. Example when the work can place date times etc. Noise etc.

Also if they cause any damage to your property. Insurance etc. May also be a place for compensation for your loss of access to your garden. See it you charge them for seeing the Solicitor as well.

When you say it is within millimetres of your fence, how many millimetres? Only a PP stated that render needed to be 15mm thick. No idea if this is accurate but, is there a possibility that once the render is in place then the fence won't go back properly because the render has taken the wall over where the fence should fit.

Don't agree and don't trust them to make good any disruption or damage they cause to your family and property. They are playing you. Their decision to build so close to your home. Their problem to solve. Not your problem. Don't agree

I was presuming you had a party wall agreement to protect damage to your side of the shared boundary in the event of damage. This is very separate to planning permission. To my understanding if upu are doing structural work on a building you need this with the people you share a wall with. It’s really to protect you both. I am surprised you don’t have this.

Did you not object at the planning stage? When our neighbour planned a similar extension I objected on the grounds that they would need access to my property in order to build it and maintain it and that I wasnt prepared to give that permission. However I did state that I had no objection to them building an extention which was in line with our existing extention ( provided proper arrangements were made to ensure no damage was done to our roof and both could be maintained independently) or if it was not on the boundary line. The extention did not go ahead.

We did an extension a few years ago. Had a few minor things with the party wall act that were rectified. Our neighbours let us render the wall and we painted it for them as they were not happy looking at a brown rendered wall but happier with a white rendered one. We obviously needed access and we all compromised and no one fell out over things.

this is just part and parcel of living with neighbours esp in terraced or semi detached houses. People do work that affect us. But at the end of the day it all swings in roundabouts and is not worth falling out over.

Don't normally post and haven't read the whole thread but they should have got a party wall agreement. I'd be speaking to my solicitor.

Probably never considered it a problem and the neighbour wouldn’t have an issue
I’ve been on both sides of this and never had any problem
builders were literally there for a few hours then sand again to finish
wouldn’t even occur to me to object

I would allow them to do it but at a time and date that suits you with a definite time line and everything needs to be moved by them and put back exactly where it was in the same or better condition than it was
You need to be compensated somehow eg perhaps they’d pay for dog daycare for your dog for the days it’s being done ?

I’m late to the conversation but, my neighbour built an extension to within inches of the boundary wall. They did use a nice brick but because it’s so close the finish is atrocious. If they ask again and you agree to let them do it, be sure to insist it’s finished to an acceptable standard. What I look at is very messy and I wonder if they have problems in the future as a result of it not being finished correctly.
