Permitted Dev : Catslide should be included in roof volume calculation ?

[jamesalangriffin007@]

Hi all
I'm doing a hip to gable conversion, with a rear dormer and have just had my lawful development refused because I failed to include the Catslide roof (circled below) in the roof volume calculation.
Including the Catslide roof, in the calculation takes me up to 55m cubed.
In my mind, what is under the Catslide roof is mainly bedroom space, with some under eave storage.
Is the planning officer right, or do you think I can argue against their position?
I can reduce the width of the rear dormer, but before doing so I just wanted the benefit of your views.
Thanks for any advice.

The planner seems to be correct if that area has roof voids - the eaves storage you mention.

The there is existing habitable rooms not voids, then you need to make that clear and deduct the volume.

Thanks for taking the time to reply Woody. What you say makes sense. I'll contact the planner to discuss. Thanks again.

Why's it taken you three weeks to respond?

Because I'm not as good and organised person as I should be. But I meant it when I said thanks.
