Do I need permission for this ?

[tom2019]

I'm building an pull up bar in my garden which consists of 2 6x6 posts dug 1m into the ground and sticking out of the ground 2.5m.

I havent conncreted them in yet but my neighbour has written a letter (which I find a bit strange as I see him almost everyday) asking me not to do it until I get permission from the council ?!

Its quite near his fence but dosen't obstruct or anything - I think he's just been difficult..

What will / can the council do? Do I need planning permission ? If he kicks up a fuss could they make me take it down?

I think im going to go ahead with concreting. I've looked at all the things you need planning permision for and this dosen't conflict with any of them.
