Garden decking height

Decking is permitted only where the height of the deck is 30cm or less than the highest bit of natural ground level it sits above. as mentioned the house floor level is irrelevant.

they use the term "next to" in case you cant get under the decking to measure as i say the house has no relevance here imagine you have removed the decking look for the highest natural point it will cover then thats your 300mm datum point

Many thanks, guys, in this case, I should apply for planning permission. How likely it could be granted? Thank you.
 
What's the definition of "natural ground level"?

If you build a house on a sloping site, whereabouts on the house is assumed to be "natural ground level"?

If you build up the ground to provide a level surface to build the house, is that all unnatural? Does it ever become natural?

If on a development of many houses they first engage in some cut and fill to level the site, where is ""natural ground level"? Does it change as soon as they stop pushing soil around? Does the new surface become "natural" after a year and a day?

What about Capability Brown scale landscaping? Who decides what is natural and what is not?

"Natural ground level" is not mentioned in guides, only "ground level"
 
OK

If you build up the ground to provide a level surface to build the house, is "ground level" what you create?

Ditto if you extend the house?

Ground level

"ground level is the surface of the ground immediately adjacent to the building in question, and would not include any addition laid on top of the ground such as decking. Where ground level is not uniform (for example if the ground is sloping), then the ground level is the highest part of the surface of the ground"

from tech.guide

It does not mean you can add to or build up the existing ground.

 
I can see how youd not be allowed to gratuitously raise the level, but in the OPs situation, the level was not raised by "an addition laid on top such as decking". The fill between A and B was clearly done to facilitate building the extension:

So allowing for footings being wider than the wall, the ground level would be that at the back of the extension....
 
The rules as stated earlier in the thread are quite clear and have been for many years.
 
So it looks like the OP made a mistake in not raising the ground level to build his extension on, instead of building well below floor level.

The ground would then have been at the right height for him to have his decking
