Planning officer not making sense comments and help needed

[Jedi]

Hi fellow members,

 

Can someone give their thoughts about my re-submission please:

My first application failed due to the depth of my extension is too big despite met the 45 degree angle (8.6m, long x 6.0m depth)

It is a bungalow that will have rear and first floor extension. A few bungalows been extended upwards and bigger than ours. 

Both of my side neighbors objected. 

In my re-submission, we reduced the depth and thus it became 8.6m long x 5.3m depth

The officer again saying the depth allowable is 4m. 

The officer seems to set his mind to allows 4m for first floor extension and OK for us to have 6m ground floor.

Can anyone tell me why is this so?

And my rear neighbor just finished building his at 10.3m (long) x 5.5m depth.
