It seems to me that the concrete/mortar fillet against the bwk is set at, or damned close to, the DPC, so your paving needs to be 150mm below that.
The hoppers seems to be set at the correct level, although the IC cover is too high, but could probably be reduced by removing a course or two of that regulating bwk.
The one pipe I can see is, as you say, shallow, but it looks as though you should just about be able to get some paving over it.....depending on just what type of paving you are considering.
