Because of the diverging views offered, I'm unsure what my rights are to the extent that I may have no grounds for asking let alone having a say on whether he does work to the wall. Indeed, I'm not sure if I own the wall.

I'm not qualified to know if they will or not and I'm fairly sure building control and planning won't be consulted.

I've just learned of "adverse possession" which suggests that my 39 year-old extension is potentially entirely on my property and that the wall in question is not a party wall. Any thoughts?

Presumably he'll need a safety railing.

He plans to run joists from the top of his single-storey extension wall, across his narrow yard to my extension wall and top it with decking. Both walls are plastered concrete block with cavity.

I talked to the planners yesterday - they say that planning permission isn't required before installation but, if he contravenes regulations, the structure will be in trouble.

The extension, built in 1981, runs along the line of the old scullery that was there beforehand. You may infer from the attached diagram that the old scullery's exterior probably aligned with the furthermost line of the party wall.

I'd need some expert advice on the integrity of his fixings and the joists' impact on my wall - on an extension whose join to the old house has been filled several times in its history due to settlement. That's my main concern; the next concern is the parties that undoubtedly will ensue.

The chimney is his (my fireplaces are on the other side). It's looking very much like it's a party wall after all. ?

So, using that logic, it is almost certainly a party wall. If so, how do I have the right to stop such fixings?

The water from his gutter runs onto mine and is released via the downspout on the other side of my extension. The only indicator of the boundary-line, according to some people, is that it's the centre-lineof the chimney.

Others say that the centre-line of the chimney is the boundary.

His chimney and mast.

I'll mention it the next time I bump into him and ask him to show me exactly what he plans to do (before he engages someone to do plans). If he says he definitely intends to attach to my wall, I'll have to turn him down as gently as possible.

It's his.

Ha-ha, you asked for it. One with the gate open would need to be accompanied with the Mission Impossible theme.

There is no garden - we both have concrete yards which are about 137cm (54") wide with 9 steps up to the back gate. Beyond planning service and council's. influence, the bottom line for me is the surety that he can't carry out works to my wall without my permission.

I'm sincerely indebted to all the sound advice if received and I'm going to need all of it. The only loose end is that there are some differences of opinion im establishing the boundary line and it's consequences for whether my wall is a party wall.

A major factor is the fact that, no matter how civil he is, I get the impression that the council and planners won't be getting any application from him!

Walking on wet wood gives me the heebie-jeebies be it decking or not.

It has put me off already and nothing's close to being erected.

He mentioned joists - that's not what I built the extension for. I suspect too that, since he's a single man in a terraced house that the space he creates isn't solely for sunbathing.

On the inside of the house, the extension is 55mm nearer to me.
