I’m building a barn (which I have pp for) the problem is that the ground isn’t level so one side is higher than the other. A neighbour has complained that it is not what was specified in the plans. Intergoogle suggests that I should use the nearest property to the build and the level of their ground as my marker to work off. Any ideas if this is correct?

Hi all! Wish I had bothered to look much earlier for a building etc forum! Big job broke out (well big for me) building a barn so I’m looking for guidance on ground work / building height on uneven ground.
