Replacing wooden fence with brickwall - pain in the *** neighbor

Disjoint

Hi all,
So I've been reading up a bit on this but wanted some form of confirmation and to see if I am missing something.
Long story short - the simple, talk to your neighbor before you do anything will not work with my current neighbor. The two other neighbors around my garden (London Victorian terraced) are normal and there is no problem. The fence surrounding my garden was visibly installed by the previous owner of my property so after reading online I surmise that it is mine. I want to go ahead and remove the fence and replace it with a brick wall (I will raise it to the maximum height of 7 feet).
I read that I do not need a party wall and this is supposedly not a party fence wall as it was clearly installed by the previous owner of my property and that replacing the fence is my right as it is my fence. The brick wall on the side of the painful neighbor will start from my side extension and go along the existing fence replacing it. Can I potentially look at slightly extending my concrete base by a few inches in his garden? (this would be covered back with dirt). What potential problems am I not seeing? The fence is not touching his building at all so he can't try and claim damage to anything on his property (something I wouldn't put past him). Is the worst thing I can expect is a very angry neighbor calling me all sorts of names while I dig a trench and pour my concrete peacefully while listening to some calm soothing music?

The type of neighbor I am dealing with:
My neighbor is a proper pain and just generally unpleasant. I needed access to replace a window when I moved in a year ago, he told me over his dead body that no one will ever go in his garden and used all sorts of nice explicit language. Started a roof extension at the moment - his daughter (relatively rude and patronizing, lovely family...) dealt with the party wall bit as he was too awful to deal with. Now he has gone to building control complaining about the fact that I am building on his party wall (building control will come next week and has hinted that it's not the first time they are hearing from him - building on the party wall was part of the plan and what was drawn in the party wall act... The man is a moron). My scaffolder put in a pole resting on his facade - he went absolutely mad at them, making all sorts of weird comments about the UK not being Palestine etc... just a top block overall (the main contractor is from Yorkshire, he was slightly confused). I removed the pole right away. I've tried to minimize noise etc... Got an angry email on Sunday that I had builders on site - the main builder is a friend and I have told him to move into the house during the lockdown... He was having a fag in the garden and never works outside building hours - I come and help with the house. It's max two of us. I used to work in construction and building work - my friend has worked on very large sites throughout the UK. Never have we dealt with such a pain, I think he is quite angry that we are just doing everything by the rule and there is nothing he can bite at - just an angry bloke.

Does this make sense to you?  If the answer is "No". Then you have your answer.
If the answer is "Yes", then you will have a problem and good luck.

Extending foundations onto a neighbour's land might be normal in connection with building work where they would have some advantage themselves, such as being able to build against a party wall so created, but you say this won't be a party wall and I'd guess you wouldn't want this guy to build a shed against it either. Therefore, if all you are doing is attempting to take away some of their garden land, I think you should expect problems.

And where do the regs say you can build to 7' without planning?  That's not the same as 2 metres is it?

From where I'm sitting, you seem to be  pushing the boundaries all round, but maybe I have misunderstood.

No, you can’t extend any part into his garden. If you want a wall then without his agreement every part, including foundations, should be on your side.

Got it - I read somewhere that for the purpose of a fence you had the right to slightly edge onto the land of your neighbor in building a base. But that seems to be only the case if as previous poster said they would derive a benefit from it. Here I just don't want him to have any potential reason to complain so will just stick to my side.

You can do 2 meters :

Which is what I intend to do.
The base I had read that you could build it across land, but as you say it would mean that he gets some benefit out of my wall. If he wants to build a shed and lean it against my wall I don't care. I just don't want him to complain. 

Overall majority seems to say stick to building the base on your land which I'll just do and not worry. I'll talk to a bricklayer to see if I can have one side of the brick work being on the edge of the concrete base, which will solve my issue.

2m high single brick with supporting piers? Double bricks? Building onto the edge?? of the required depth/width of foundations you will need.

You definitely need to speak to a bricklayer/builder. You are, unless built well away from boundary going to disturb neighbours land.

I would just reconsider just putting up a good quality 2m fence.

A 2m high brick wall is going to need pretty good foundations and take a while to build.

Concrete posts with panels can be thrown up in less than a day - If something a bit more bullet proof than wooden panels is required, the OP could use extra large gravel boards.

  Then why did you say you were building to 7'?

It was me who, by inference, referred to the 2m height limit on the boundary.

This thread has to be a wind up, surely?

Possible? But not sure. Op is talking about feet not metres, so not some school kid being bored?

But Op has builder friend staying there and has to ask bricklayer about foundations?

I would say no way, would I let someone build a possibly substantial heavy wall right up to the foundation edge.

For a 2m wall, foundations are going to be messy. Why op is willing to lose a "substantial" part of the garden to the "nasty neighbour" I do not understand?

Freebear's. Suggestion is the one I would also suggest if neighbour is as OP suggests.

Sorry! My opinions only. Will wait and see what OP's intake is?
