Projects in Northern Ireland need planning clearance from one of the eleven councils and building control approval, also from the council. The Party Wall etc. Act does not extend to Northern Ireland, so work near neighbours is agreed directly and documented carefully.
We prepare planning applications to the council and building control submissions for Northern Ireland projects.
What should I think about before starting?
- Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
- Conservation areas and listed buildings need extra design care and supporting statements.
What happens after I enquire?
