To think neighbours are being selfish over extension?

[nearlynot]

Extension is ground and first floor, 5.5 meters long, with ground level extending a bit further. West facing.

Is neighbour BU to object if half the garden will have no extension or shadowing. Neighbour always home and claims it will be detrimental to have shadow over back of the house/windows. Who is BU?

This sounds like reverse

I don’t think they are necessarily being unreasonable. As others have said, it sounds as though it will dramatically change features of their property (I.e. light garden). That said, sometime compromise is the best solution. The people who owned our property before us contested some building work on the property opposite. I believe it was because it would affect a long range view. The people opposite have since grown the most enormous trees, which not only block the view, but stop the light. I can’t help but think some negotiation might have made everyone happier.

We had lived in our bungalow for over 10 years and got on very well with our elderly neighbour the whole time. Neighbour unfortunately died, new neighbours moved in, started straight away on an extension that massively impacted our privacy. We objected but they got the go ahead anyway. The whole thing was very stressful, noisy, messy; the one place you should be able to relax is your home and we couldnt! I truly believe it was one of the contributing factors to the stress that killed my husband a few months later.

Once the extension is complete, would it BU to not allow the neighbour complaining to then use said new driveway for access to complete building work on their property (albeit smaller work)?

You sound horrible. I would hate to live next door to you. Why don’t you do your neighbour a favour and move?

On light and shade, that will depend on the plans and the impact. Nobody can say for sure.

On the access via your drive to allow them to do work: if you blocked it you would be very petty and it would create needless conflict. Why do it?

On neighbors moving out during your building works: that's up to them. As long as council noise requirements are followed and work is done within reasonable hours then that's life. Some people work nights, shifts, work from home, work out of the home, have children etc and nobody can schedule building work around the preferences of their neighbours. Courtesy would be reasonable and some notice if you know when the heavy noise days will be

Even as a reverse it's still bad

Their objections may well be upheld; loss of light and overbearing are reasons some were refused locally. Don’t be too smug just yet, op.
It’s not quite in the bag.

It sounds horrendous. Buy a bigger house. Your poor neighbour.

I hope planning permission is denied, especially as you seem to think it's ok to work all day Saturdays. It isn't.

If I was your neighbour I'd object every inch of the way and complain every time work went on outside permitted hours.

This has to be a reverse.....
Whoever is doing all this building work sounds like a bloody nightmare

Either this is a reverse or you’re a massively selfish nightmare neighbour. Either way YABVU

I've added a diagram. Neighbour 1 already had permission and completed their extension years ago. Thanks for the opinions. We all have front gardens aswel, big enough to park a car or have a lawn or planting.

Which neighbour are you nearlynot?

I think people should have to pay immediate neighbours compensation for doing long term building work affecting the neighbours quality of life and enjoyment of their homes.

Bloody hell, that's awful. Just buy a bigger house!

The “unaffected garden” is completely irrelevant! The actual house will be cast into shadow. How dim are you?

So basically you're saying that the neighbour won't be able to sit in the sunshine in the summer if they stay near their house? Whereas you'll have the joy of being able to step out of your back door onto your sunny patio?

And if they carry on moaning they can't use the shared drive for their own work.

I hope they extend beyond your new back extension - I would.

So the shadow from the extension would essentially be permenantly blocking light from both the back and side of neighbour 2 house? No way should that be given permission. It's a ridiculously huge extension compared to neighbour number 1

Wow poor neighbour 2

Hope for them that the plans don’t get approved.
How selfish.

This sort of thing can really affect someone’s wellbeing

If you're neighbour 2 object away.

If you're the one in the muddle, move.

Is it unreasonable to anyone or unheard of if the builders can work on a Saturday to leave one week day quiet

Most local councils have rules governing when work can be done. Some don't allow work on a weekend, I believe - generally not at all on Sundays, and only between certain hours on Saturdays.

The rest of your posts make you sound obnoxious. I assume it's you wanting to build this monstrosity, though I'll be charitable and accept it might be a reverse...

That really is awful. You're stealing their light.

If you build it I hope they grow Leylandi right up against it and steal your light. How utterly selfish.

That proposed extension is horrendous - it would ruin their neighbours home, and devalue their property.
It makes me want to get on the planning portal and object myself

Neighbour 2 is getting a really shite deal there. I would be going mad and would object as much as possible.

I'm afraid that I would object to those plans and I'm pretty easy going when it comes to extensions
It's a massive impact on them and the value of their property. Naturally they are unhappy about your plans (I'm assuming it's you, but it would help if you could clarify so ppl can give you advice).

'Unaffected garden'

FFS!
