Planning and building regulations in Downpatrick
Approvals for a set of architectural drawings in Downpatrick follow the rules for Northern Ireland. In Northern Ireland drawings are prepared for the council’s planning service and building control.
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
