The legislation does not refer to 'decking', but part E 1 (h) simply states that it is not PD if the development
"would include the provision of a verandah, balcony or raised platform". This is why the planning officer calls it a 'raised platform'.
In the interpretation section to the rules, it states:
"raised" in relation to a platform means a platform with a height greater than 0.3m.
The general rule is that 'height' is measured from the highest part of the natural ground level adjacent to the structure, so if the decking is less than 30cm above g.l. at the house end, it should be P.D. However, there was one specific case noted on the Planning Jungle website where an appeal inspector included the height of the balustrade within the overal height, and thus refused the appeal on the grounds that the height of the structure (ie decking + balustrade) was more than 30cm above natural g.l.
But that case does seem to be an outlier as it seems inconceivable that a platform more than - say - 60cm above the ground at any point should not have a guard rail/balustrade.
If the council issues an Enforcement notice, the OP must respond (even if the council's stance is unreasonable) otherwise the E.N. will come into effect automatically at the end of the stated period, and give the council power to remove it.
