Permitted Development – Hip to Gable conversion

I wonder if any of you can help me please. We are looking at converting our house from hipped roof to gable roof under permitted development. However, the local authority are stating that it isn’t permitted development as the gable that we want to convert to isn’t a true gable (it has a 1.5m flat running the width on the top). If you can imagine, the gable is like a triangle but with the top chopped off to create a flat at the top of the gable.

Under permitted development does it state anywhere what the shape of the roof has to be?

The land isn’t on designated land and the proposed changed doesn’t exceed the limit of 50m³. The changes do not extend the plane of the existing roof slope on the principle elevation that fronts the main road. The  materials that will be used will match those currently used and the roof height will not exceed the roof that is currently in place. There are no verandas, balconies or raised platforms to take into consideration, and there are no side facing windows that will be added.

Based on all of the above, I can’t see how we are doing anything against the rues of permitted development, but my local authority keep stating that we aren’t changing it to a triangular gable.

Any help would be really appreciated.

Many thanks
