    Hi Everyone!

    I have scoured this thread for answers to my planning query - which is around from which point we measure the eaves height for our proposed single-storey rear extension (Double pitch roof). Our property is located on flat ground, however the garden slope down! The ground slopes downward from the end of the patio to the end of the garden" as in the side view below.

    Level A is same all around the house and level B is where my extension finishes in the garden. The proposed extension is shown by Blue lines in the plan view

    The issue we are having is from where we can take our maximum 3m eaves measurement when planning the 6-meter extension - We hope for our application to fall under PD, however the planning dept. at the local council invalidated the drawings which sent in as the eaves height is too large. They seemed to completely overlook the sloping ground here?

    I hope the diagrams I have included make sense[​IMG] If we took the eaves height to be 3m at the level B, that would give us a height of 2.5m at the start of the extension in that diagram.

    Absolutely any help and guidance you could provide a noob in need would be much appreciated!
