Main issues, as the Inspector framed them

  • Whether the prior approval application was made before beginning the development as required by paragraph A.4(10) of the GPDO

What decided it

Development had commenced on site before prior approval was obtained, making it impossible to grant prior approval retrospectively and rendering the development non-compliant with paragraph A.4(10) of the GPDO.
