Neighbours extension on boundary wall/line

[Deleted User] · 03-06-2012 10:23am #1

Hi folks,

Hoping someone can help us with this one..

We are currently looking at getting an extension to the rear of our house. One story ~25sqm. However, as we noticed some time back, our neighbours, who have been here since before we bought our house, have an extension at the rear of their house that's external wall is clearly built on/over the boundary line. The dividing wall that runs up the garden runs directly into their extension wall. Also their drainage, fascia etc are clearly on our property as well as the wall being either fully or partly on our property.

Where do we stand on this? Our builder says ye can tie our wall into theirs and actually use it as is. But would need permission from the neighbour. However if they declined we would lose 2-3ft as we would need to build a new wall..

Can we kick up about this at all? The extension might have been built at time of house construction - would this make a difference?

Really just looking for some comment/opinion/direction..

Thank you,
Brian

I assume from the above quote, that the extention was there when you bought your home.
Did it not feature at the time in say any Survey's you may have done on the property, prior to purchase.is it mentioned by your Solicitor at the time of purchase.
Boundary lines are difficult to be acurate on, you would need the site map's rather than just relying on where the wall is.
If it's there some time you may just have to reach a comprimise with neighbour that you build onto their wall, otherwise if it's as you describe major headache,

That's pretty much it Brian, If the structure is there more than 7 years ,the neighbours can choose to be difficult.

Speak to your neighbours, apart from the guttering and space loss, ideally you need to find out was a decent foundation placed under the boundary wall before their extension was built. If not , loosing the 2/3ft might not be a bad thing..

Also consider seeking a section 5 exemption from your local authority, getting an engineer to check boundary & structure, and an arch/ tech to prepare layout & detailed drawings/spec.

Thanks to you both for your replies. Haven't spoken to them just yet so they may well be fine but just wanted to get an idea of where we might stand.

Good point about the depth of the foundation too. I don't know what a section 5 exemption is by the way? Can you tell me please?

Again - thanks to you both
Brian

Presuming your proposed extension is exemept. for a few quid and basic drawings, the local authority will confirm this in writing-it takes a max of six weeks
As buying and selling property tightens up, an exemption cert and of course building reg cert is advisable

There is also a newish bit of legalisation regarding building against another owners habitable property. (I don't have it to hand right now) but these are the things worth checking with a professional other than a builer, prior to works beginning.

The legislation to check is the Land and Conveyancing Law Reform Act 2009, which gives landowners new statutory rights in dealing with party walls or any type of structure on or at a boundary. Talk to a professional - it's worth the money.

hi , it may not be applicable. the reason for my comments above were from experience of dealing with neighbours on these sort of extensions. if you go along with a clear set of drawings and the planning authority on-side your neighbours are inclined to trust your project/ extension will be done properly and they'll be less likely to cause a scene

BryanF, that quote you posted is about demolition, or am I reading it wrong.
The OP is questioning an extention, not a demolition.

Any connection.

thanks

yep your right, but the grey area is where you have to go digging to check foundations are adequate and ultimately decide if any structural works are required to strengthen the party wall or loose the 2/3 ft + you've got to interfere with the neighbours eaves/flashing/gutter and roofing to tie in

i appreciate, ive given an extreme response as i hadn't the abstract to hand when i was writing the original comment and i'm now trying to dig my way out:D

Thanks for that, and hope you get out of the hole soon.
My reason for questioning the posts, is that while I agree entirely with advice to consult a professional, I am weary of quotes like.

but these are the things worth checking with a professional a other than builder, prior to works beginning.

it suggests we know little,

and I am particularly interested in more information on,

I may be wrong, but that just muddies the waters.

I don't see the relevance of the extension being there 7 years if it is clearly over the boundary line, provided it has (as a rough rule as there are other criteria) not been there longer than 12 and capable of adverse possession.

If you were able to establish the age of their extension this would be helpful. A proper opinion on the boundary line may be useful as a bargaining tool and hopefully wouldn't cause irreparable damage to relations with your neighbours.

The nuclear option that may be available would be an Order compelling your neighbour to remove any part of their building on your property - I'm sure you would probably not even contemplate this but if his extension is approaching 12 years you should possibly contemplate proper legal advice as you may lose any rights of action if the period expires.

It's a complex area, there have been threads on this in the legal discussion forum and there is a lot of very dangerous advice floating around.

Your neighbour couldn't have planning for this ,check with council planning ,you will have to keep pushing the issue to get results

If part of your neighbours boundry wall is on my land, would this make it harder to sell, it's there since I bought the property

If it’s on your land then it’s not a boundary wall. It’s a wall on your land.
