• 19/04/2013: Letter from Eric Pickles to MPs - On 19/04/2013, Eric Pickles wrote a letter to MPs setting out the revised version of the proposed changes to Part 1 of the GPDO.  According to this letter:
  "- Homeowners wishing to build extensions under the new powers would notify their local council with the details.
  - The council would then inform the adjoining neighbours – this already happens for planning applications.
  - If no objections are made to the council by the neighbours within a set period, the development can proceed.
  - If objections are raised by neighbours, the council will consider whether the development would have an unacceptable impact on neighbours’ amenity.
  - This is a form of ‘prior approval’ process which allows for consideration by ward councillors, and (if the council wishes) by a Planning Committee.
  - There will be no fee for householders to go through this process." (pdf) (link).
