I presume you're worried about your neighbours and the need for

Erect it in a small hollow?


I've already dug out at one end (the adjacent ground on the higher
ground level end is the one that planning should use, although the chap
I spoke to at planning was initially unaware of this), BUT it only gives
me about 225mm of "extra", and I need more like 400 for that to work...

So, as I ain't intending to dig up the reinforced pad I laid, having
mixed the concrete in my Aldi mixer, about 5 cu metres of it, the roof
must comply!

Fit the existing trusses a bit lower.

And bend your knees, if you are tall?

I would use the existing trusses your neighbour is highly unlikely to know all the rules regarding permitted development. If someone makes an issue about it, just apply for retrospective planning permission which is the way things are done round here and for some right old monstrosities to boot so a few centimetres of excess height is not going to be an issue.
