Whether you are planning an extension, a major renovation or a new home, two approvals come up again and again: planning permission and building control. They are often confused, but they are separate processes with different purposes – and on many projects you need both.
What planning permission covers
Planning is about whether a development is acceptable in principle and how it affects its surroundings: its size, appearance, use, and impact on neighbours and the local area. In Northern Ireland, most planning applications are decided by your local council, which assesses them against its development plan and regional planning policy.
Permitted development
Some smaller works to houses can be carried out without a planning application under permitted development rights. Many modest rear extensions, some outbuildings and certain alterations can fall into this category, provided they meet strict limits on size, height and position. Those rights are more restricted – or removed altogether – in conservation areas, for listed buildings and on some newer developments. If you are unsure, it is worth checking with the council or asking for a Certificate of Lawful Development before you start.
What building control covers
Building control is about how the work is built. The Building Regulations (Northern Ireland) set standards for structure, fire safety, drainage, ventilation, energy efficiency and accessibility. Even where planning permission isn’t needed, most extensions, structural alterations, loft conversions and new builds need building control approval, with council inspectors visiting at key stages such as foundations, drainage and completion.
Listed buildings and conservation areas
If your property is listed, separate listed building consent is needed for works that affect its character, inside or out. Conservation areas bring extra controls too. These projects need careful design and experienced tradespeople who understand traditional materials.
Timing your project
Planning decisions can take several months, so it pays to start early. Building control plans can be prepared in parallel. Allowing time for both avoids the frustration of having a builder ready to start and no approval in place.
How the right builder helps
An experienced contractor will work alongside your architect or designer, build strictly to the approved drawings, and coordinate inspections so there are no surprises at completion. At SC Developments, we have been delivering new builds, extensions and renovations across Northern Ireland for many years.
