An Irish planning exemption should be checked against the actual property and current rules, including earlier extensions and the remaining private open space. Do not import UK “permitted development” language or assume a size figure settles the question.

Assemble the Irish planning facts

  • Property address and local planning authority.
  • Existing house and site drawings.
  • Dimensions, height and location of every previous extension.
  • Proposed conservatory dimensions and boundary distances.
  • Remaining garden or private open space.
  • Protected-structure, architectural-conservation or planning-condition context.
  • Intended external materials and roof form.

Use Ireland’s official planning information and the local authority. Where exemption status is uncertain, ask about the formal declaration process available under Irish planning legislation. Building Regulations and structural suitability remain separate matters.

FAQs

How can previous extensions affect the enquiry?

The assessment may consider the combined extension history and remaining site conditions, so list all relevant additions rather than only the new conservatory.

What should I ask if an exemption is uncertain?

Ask the planning authority or a qualified Irish planning professional what documentation and formal determination route can establish the position.
