mike sewell,
Recently been to a house where a large extension has been added, the patio abuts the outside walls and is at the same level as the inside floor. The BI insisted that 100mm of the joints between the paving slabs and about 50mm out from the house were filled with gravel. As far as I could see the DPC was at patio level and no special vertical damp-proofing measures had been taken (the walls were rendered and painted). Yes it was approved for B regs.
