To deny neighbour access to render extension?

Semi detached neighbours are building extension within millimeters of the shared fence allowing no access from their own property for maintenance. Predictibly, they now want access to my garden to render the outside and to do this they would need to remove the fence and everything near the fence like my seating area, storage box, potted plants etc. I don't want to agree to this. There's the inconvenience of not being able to use our garden, DCs wont be able to play outside and I'd have to keep the dog in. My main issue is that the layout of the houses means the wall is literally right outside my kitchen/livingroom window which feels really close and intrusive and when people are working on it they are literally looking right at me sitting in my house. I don't want workman coming any closer into our space - we are trying to enjoy the nice weather and it's been quite disruptive as it is.

Anyone had experience with this? Its really stressing me out as I don't like to be deliberately obstructive but I strongly don't want to agree to this and feel it's not my problem to solve. I accept that refusal might mean forever looking at an ugly wall but I plan to grow something climbing to mask it.

They are waiting for an answer.

AIBU to say 'no'?

Edited to add that they don't want access right now - just at some point.

As they were the only neighbours not legally notified of the work they didn’t know about it!

Where does the OP say this?? Or are you talking about a different poster?

I'd just let them. It'll be inconvenient but sometimes in life things are. I'd rather be a good neighbour than be deliberately awkward.

She’s not being deliberately awkward. Her reasons for refusing access are perfectly reasonable.

There is a lot to be said about just doing the neighbourly thing.
Some day you may appreciate their help with something.
So what if you are inconvenienced for a week, its worth it for neighbourly harmony.

Sounds like you are jealous of their extension TBH.

it's the CF neighbour who should have done the neighbourly thing, and go for harmony!

Bit rich to expect the OP to pick up the pieces and deal with the bad planning (or intentional planning because they are CF in the first place)

MikeRafone · 31/05/2026 15:18

I will add on both occasions I have helped neighbours, this has saved me greatly

The first time the neighbour wanted to repoint her wall, the scaffolding had to go up in my side alley for them to do this - they repointed parts of my wall at the same time and it was free.

The other side had extensive works done by the builder that had done our roof - the builder used our electric at times as a favour and he repointed the chimney stack, when I went to pay him he refused as id allowed him to use out electric

Probably saved me near on £2k getting a builder in to do the work at another time for both jobs

The extension is being built within millimeters of the boundary fence but they have not needed to cross the boundary at all to construct it. All done from their side until now. They now want to take the fence down and come to my garden to render it.

If it's a new wall with finished brick why does it need rendering?

I'd likely just say I'm sorry it's not convenient to provide access.

MikeRafone · 31/05/2026 15:13

I would want to know the following, in your shoes

When is this work likely to take place? As if its the summer months - then I would like to defer to the autumn

Will you provide a privacy screen? whilst the work is being done a privacy screen to allow us to continue having privacy in our home

How are you going to contain my dog? if you want to take the fencing down, the dog is out in the garden and needs to be kept secure

How long is this work gong to take place? I don't want the fence taken down and then nothing happens for 3 weeks, id like the work to take place in as short a time as possible and be concentrated, the fence rejected and we can all get on with our lives again

If you set out your concerns, then they have a chance to put into place actions to have the least disruption to you.

MissMoneyFairy · 31/05/2026 14:08

In what way? I'd be more concerned about the space, there won't be any airflow, are there windows above the wall.

Taking legal advice, going to court for a start ?
It's a bit of rendering on a wall, not full on earthworks with possible subsidence to OP's house. It doesn't take long to do.
I get that OP is pissed off about the extention but as suggested she could grow climbing plants up her fence along side it when it is finished.
It's not exactly a hardship to endure, ad I say that as someone who found a previous neighbours conservatory right to my fence as a pita.

Offherrockingchair · 31/05/2026 15:05

Well, surely they should have thought about this before they built. What happens if you build an extension in the same way and there’s literally 2cm or whatever between the two walls? Surely any work they need to do now relies on your space. You might want to build similarly, or put a shed there, or a pond, or a massive statue! They sound very entitled and I’d say no!

Mabalabs · 31/05/2026 15:05

I would not allow this inconvenience into my garden. They should of thought about that, before enclosing the space.

BillieWiper · 31/05/2026 15:01

I think denying them access to do so would be unnecessarily mean spirited. It could be more trouble then it's worth.

Presumably it's physically necessary. If they are legally allowed to place the extension that close to boundary without planning then it is what it is. If they did need planning you should've objected.

I guess they need you to agree so you could ask for payment of some sort. But cordial neighbourly relationships are worth more than money sometimes.

Duvetdayneeded · 31/05/2026 15:00

It will look better if they render it. Take lots of photos and share them, make them liable for any damage, and give strict timeframes, ie Tuesday and Wednesday.

TheyGrewUp · 31/05/2026 14:59

With these things you always have to take the long view. When we took the back off a former house for an extension, planning permission required, we liaised with the owners next door and went up to the party wall, so thay if they or future owners also wanted to extend, it could be done flush. Far better for all concerned.

@Amberlynnswashcloth allow them access but do it with a proper agreement in place.

YourPoliteTurtle · 31/05/2026 14:59

These people always are CF, they push their own boundaries as much as they could because they assume they can then use somebody else's property for access and maintenance.

What happens if the OP decides to build an extension within millimetres of the fence too? They won't have access either. They just count on the neighbour having to suck it up, and being now unable to build an extension themselves.

Whowhatwhere21 · 31/05/2026 14:56

I have always been the person to say yes to these kind of things as my thought would be, I'm inconvenienced for a couple of days and i can live with that. However, from personal experience I would never say yes again.

I had a slightly different situation where my fence and gate needed to come out for a neighbour to build their balcony. I was told it would be a day. It was 3 days, no fence up, I have a dog who I couldn't let out. I came home from work on day 3 to the neighbours new balcony 10cm across the boundary into my garden, my fence posts removed, my fence panel now screwed to their balcony by 4 screws, and my gate also 10cm across the boundary screwed into a post with 2 screws. And a shit load of dried concrete all over my patio. That was 2 years ago and its still the same as the day the builder left as the neighbours don't give a shit.
They should have checked with you before starting work if its important to them. That's now my view.

theresnolimits · 31/05/2026 14:55

I would say the ‘agreement’ isn’t worth the paper it’s written on. What if they wreck the fence and refuse to fix it? You then have all the legal hassle of taking them to court etc. The builders will blame them, they’ll blame the builders. You have to sue the builders, they may be fly by nights.

It was arrogant to assume they could do this without discussing first. You say there’s a fence so you don’t have to see it - just say no, it’s too. disruptive.

You don’t like them and think they’re selfish. They have to live with the fall out of their attitude.

DaisyDooley · 31/05/2026 14:54

I would consider allowing them to -but I would insist on a legal agreement being drawn up and £££ put into escrow to ensure that you don’t have to fight to pay for repairs to your garden & fence.
No way would l just allow their builders -who won’t give a shit about your privacy/garden - access without a proper agreement especially in light of what you say about their previous behaviour.
I would also want a set timeframe with penalties.

My thoughts too but we have no diagram,, photo or know how high the wall is, if its brick or blocks, if there are windows or guttering so difficult to offer any advice.

Our cheeky neighbour wanted to build their extension wall on our boundary with overhang. Then agreed to a few mm inside then a ft inside, then gave up and decided not to build it no idea why as once it was off our boundary and wouldn’t overhang I wasn’t fussed tbh.

Just started digging out the foundations and knocking down our garden wall, like they where digging our side of the boundary for their foundation. “it not matter when grass and plant go back you won’t see” 🤦🏻‍♀️🤦🏻‍♀️ “no problem see” 😩

Had a rather dumb look on their faces when I then said so I can tunnel all the way under your garden then as long as you can’t see it?? 😉

Cheeky fuckers. There is always a type who will chance it and if you give an inch or Mm will take a mile.

FarmersWife2019 · 31/05/2026 14:54

I don’t understand why they can’t gain access to the rear of their property through their own house. Surely they realised this would be an issue for everything going forwards. Cleaning out guttering, taking the lawnmower in and out to be serviced, updating childrens toys such as slide, trampoline etc. Builders and building materials can travel through their house inconveniencing them and not you.

Northermcharn · 31/05/2026 14:50

Ah just let them. When it's done it's done and it won't take long.

YouputthetwatinKathleen · 31/05/2026 14:49

Get a proper access license, with provisions about damage and reparations drawn up by your solicitor at your neighbour's expense. Charge them a daily fee for the period when their workmen and their workmen's equipment, scaffolding etc is on your property until the work is completely finished, all reparations have been made to your fence and any other damage to your side, and they have cleared off. The daily fee will hopefully focus their minds on sorting it out quickly.

MumOfTheMoos · 31/05/2026 14:48

I would because looking at render is probably better than bare bricks.

Motomum23 · 31/05/2026 14:48

Personally id say no - your fence is unlikely to be re-errected without some damage and why on earth would you give up time in your garden for their ease.

MissMoneyFairy · 31/05/2026 14:46

Tableforjoan · 31/05/2026 14:43

Also with it being mm away. How is the guttering / rain run being dealt with.

My thoughts too but we have no diagram,, photo or know how high the wall is, if its brick or blocks, if there are windows or guttering so difficult to offer any advice.
