The "GPDO Part 1 (All Classes) - LDC Appeal Decisions" document has been updated to include 3 additional appeal decisions relating to householder permitted development legislation, for which the conclusions are as follows:

July 2025 - Code a01818 (appeal dismissed):

• This appeal decision provides an example of where it was concluded that the following materials are not “of a similar appearance” to one-another:
  - external wall insulation (with a render appearance) versus bricks.
  [Note: On the proposed walls of the main house versus on the existing walls of the main house (respectively)].
• This appeal decision provides an example of where it was concluded that it is necessary for the materials used for the new works to be “of a similar appearance” to the predominant materials of the existing house (i.e. it is not sufficient to be similar to the materials used on only relatively minor parts of the existing house). (*)
  [Conclusion: The rear and side infill walls of the main house (after the installation of external wall insulation with a render appearance) can’t be similar to the stone detailing around the front windows and front door (or the “tiny amount of render at both the front and rear [elevations]”)].
