The "GPDO Part 1 (All Classes) - LDC Appeal Decisions" document has been updated to include 5 additional appeal decisions relating to householder permitted development legislation, for which the conclusions are as follows:

March 2018 - Code a00912 (appeal dismissed):

• For the purposes of the post-06/04/2014 version(s) of B.2(b), where the original eaves have been removed and not reinstated, then it is not possible to comply with B.2(b)(i)(aa). [Note: This conclusion assumes that the roof extension does not fall within the exceptions set out by B.2(b)(i)].
  [Note: The original eaves would be removed as part of the current works].
• In the second of the above diagrams, (at least) part of “Roof Extension D” “extends beyond” the outside face of “Wall 1” (i.e. for the purposes of B.2(b)(ii)). [Note: The diagrams are viewable within the “Extend beyond” topic of this document].
  [Conclusion: The roof extension does not comply with B.2(b)(ii) for the above reason].
• This appeal decision provides an example of where it was concluded that a particular roof extension does not constitute “an enlargement which joins the original roof to the roof of a rear or side extension” for the purposes of B.2(b). (*)
  [Note: The proposed rear dormer would join the main rear roof onto the flat roof of the original two-storey rear projection].
• For the purposes of the post-06/04/2014 version(s) of Part 1 of the GPDO, where a property has an original rear projection with a flat roof, which is lower than the main rear roof, then an “L”-shaped roof extension (or similar) that extends from the main rear roof onto the flat roof of the original rear projection is not permitted development. [Note: The roof extension, for all of its (rearmost) width, extends across the original rear eaves]. (*)
  [Conclusion: The works are contrary to B.2(b)(ii), noting that the roof extension does not constitute “an enlargement which joins the original roof to the roof of a rear or side extension”].

March 2018 - Code a00911 (appeal allowed):

• Where the original house has a pitched or hipped roof, then it is possible for an extension with a crown roof (i.e. a roof with a flat area in the centre and pitches at the sides) or similar (i.e. a pitched roof with a similar flat area) to comply with A.3(c). (*)
  [Note: The extension has two hipped roofs, which would be joined by a flat area (a valley gutter with width approx 0.3m)].
