What is a planning or building regulations application?

Planning permission decides whether a project can be built; building regulations decide how it must be built. Most extensions, lofts and conversions need building regulations approval even when planning permission is not required.

Planning and building regulations in Lisburn
The approval route for Lisburn is set by planning law in Northern Ireland. In Northern Ireland planning applications go to one of the 11 councils, which also provide 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.
We check this for your address before design work starts, so there are no surprises later.

What we take care of:
- Certificate of lawfulness applications
