Main issues, as the Inspector framed them

Whether or not the proposal would accord with the provisions of Part 1, Class AA, with particular regard to the external appearance of the dwellinghouse

What decided it

The GPDO expressly permits enlargements of dwellinghouses involving additional storeys irrespective of impact on the surrounding area, and the prior approval assessment is limited to the external appearance of the dwellinghouse itself, which the proposal respects through matching materials and architectural detailing.
