Neighbours planning rear dormer extension.

Slips36

We moved in our house two months ago and on second day received letter addressed to owner about neighbour planning permission to extend rear extension under prior approval. His planning permission got declined by the council.
This afternoon I saw the owner/ landlord and his builder pointing towards the rear dormer, I’m thinking the owner is planning to extend the rear dormer. Will he require planning permission? 
The neighbours house is on the right.

Yes, he will.

Do you mean the one in the middle of the picture?  If so how can they extend the dormer when it already occupies the whole roof space?

Or do you mean on the right the other side of that wall which does not currently have a dormer?  In which case yes, they can add a rear dormer within permitted development.

As there's already dormers there doesn't that set a precedent

Unless you happen to know that they live in a listed building, no they won't! 

A dormer conversion falls under permitted development for most properties.  

OP, if that is your dormer on the left, you'll
want a party wall agreement and your neighbour should be paying you half the current cost of building up the party wall that the previous owners already did, as part of the Award.

Is this the HMO where you have the antisocial tenants making the neighbours' lives a misery? If so the landlord might be trying to squeeze in more bedrooms. Worth looking at the HMO regulations and a floorpan of the house to see if there are grounds for objecting to the council. 

Do you know on what grounds his previous application was rejected?

Yes the middle one, there is about 6 feet space between the rear dormer and end of the building the pic taken from the garden doesn’t show the space.

Yes the anti social tenants. His previous application was for rear extension and turned down for light loss and overbearing presence to his other neighbour.

Yes the dormer on the left is mine but it was built in 1989. The party wall agreement must have been with previous owners.
