Do you need planning permission for a house renovation in Lisburn?
Before anything is built in Lisburn, we confirm which approvals apply in Northern Ireland. In Northern Ireland structural and notifiable renovation work needs building control approval; listed homes need listed building consent.
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.
We check this for your address before design work starts, so there are no surprises later.
