The "ground-level dpc" is actually required to be at least 150mm above the ground level (See Building Regulations for England & Wales - Part C, Section 5.5). This is to reduce the incidence of 'splashback' from rain, and to ensure a minimum amount of elevation above standing water that may come about in exceptionally heavy rain or other incidents, such as allowing the hosepipe to run unchecked. Could be an issue if you come to sell the house and a surveyor picks up on your new proposal.
