Cheesy Crumpet

Garden length is 60 72 foot from the new extension

Perfect, that pretty much says it all. If I take the measurement from the Yorkstone that formed the floor of the outbuilding we took down (build in 1886) then the measurement is under 240mm.

Thanks guys. The drawings submitted make no mention of the patio in text but there are several drawings referencing the patio height

Hi everyone, Looking for some advice. We are in the process of building a raised patio on the back of our extension. My neighbour has just called around and said they are not happy with the height and we need planning permission. I'll be honest I was ignorant to us needing permission of any kind but was aware that the height may be a slight issue (the plan was to have screening plants to enhance both ours and their privacy) I've looked into the 300mm rule but I can't figure out where to measure from and to? Is it the original house before the extension? The highest point of the patio (the garden slopes away) Or somewhere else? Thanks in advance
