Looking out of our window at the extension being built on the house opposite.

It looks like they have mistaken the 1m separation rule and read it as 1cm. If you look at the photo you can see where they have had to shorten the guttering of the house next door in order to fit the wall. I can't see how this is within the regulations, however, it isn't my house so I don't think I should interfere.

What's the "1m separation rule" ?

I think that they've just removed next door's guttering temporarily whilst the scaffolding is there. It's going to be very difficult to fit a soffit, facia and gutter in that space though.

As long as they have planning permission, building regs approval and a building over agreement they should be OK.

My understanding was that it was usual to keep at least 1 meter between houses, yes I am aware that party wall agreements are a thing but this just looks horrendous and I can't see that having the rain running off the neighbours sloping roof straight onto the extension wall now the gutter has been removed can be a good thing.

1M is something to do with fire regs i think?

It might be helpful if there was something like a 1m rule, that extension is a good illustration of why, but there is not. If you want a semi-detached house, you should buy one rather than convert a detached house into one.

You may be able to see the plans on the planning portal.

So not an actual planning rule? Surely if their plans broke the planning rules they would not have been approved? Or are they building something different to the plans that were approved? Have you had a look at the plans on the planning portal?

That’s all I can see. There is a lot scope for damp issues on both properties in the coming years - even assuming the gutter is being put back.

The local council planning website will definitely have them, although that might not need planning depending on hight/size etc. It does look like it would, hight to the eaves looks too high already for PD.

That's assuming any exist.

Far too common these days for people to do whatever they want first then try to sort it out with retrospective permission after they've done what they wanted. Slightly risky game but often works.

That said I have just been watching someone remediate their project - planning says house had to match others (brick/tile), they build a white render/anthracite windows thing anyway, now having to redo the whole outside with brick slips.

Looks to me that the house on the right has already extended. So why shouldn't the house on the left have the same rights confused I'd put money on planning has been sought and passed and all above board.

Anything to do with those return walls is going to be difficult - pointing, removing ivy etc.

OP, do you have today's updated photo?

That applies to first floor - not ground floor. Which is why you see first floor side extensions always set in further than the ground floor.

There is no scaffolding (the metal on the end is a bricklayers profile), looks like the walls have been built overhand with no room left for any guttering to go back in place, as others have said the rain water running off directly onto the new walls will cause damp issues

What a ridiculous bit of work.

If they were that desperate for increased size and space then surely the answer is to move.

Well, the scaffolding has finally gone. But there is no change to the guttering, still just the cut section and to me there doesn't look to be any way to replace it. What are the chances of damp on one or both of these walls? Oh and to the person who thought that the house on the other side had been extended, no it hasn't, the room was originally the integral garage but they bricked up the door and added a window, but the structure was there all along.

If I lived in the house on the right I’d have taken my Kango to that by now, that’s ridiculous.

I agree with the sentiment but neither we nor the OP have much interest so...
