DPC with raised grass verge DWH

[Waxza]

Question about level of DPC: please see picture attached.
I’m unsure if this is acceptable. On the whole the DPC is at the correct level around the house. However, near the front door the grass ramps up to the front door flags and goes above the level of the DPC or just touches it. You can see the level of the DPC to the right of the picture and how the grass ramps up to its level.
This is a new build DWH home. Any thoughts on whether there is a case to argue here or what remedial action might be required?

This is because in order to comply with Part M building regulations (Mobility access) the main door needs to have a level threshold ie ramped. DPC will always be under to door threshold so the ramped up grass either side is done to hide the bedding etc under the paving slabs. 

Most times the dpc is not bridged and splashes from the ground on to the brickwork above the dpc during rain are unlikely if there is also a porch over the front door.

If you get damp brickwork in this area and green mould, report it to David Wilson Homes. They shoudl lower the ground either side to 150mm below the door threshold, perhaps tidying up the paving edges with some low level bricks.
