FAQs About Building House Extensions In Ireland

How much does a house extension cost in Ireland?

The house extension cost in Ireland generally depends on the size and type of attachment built.

Some factors that will affect the cost include the materials used, the labour required, and any permits or planning permissions that need to be obtained. To find the total cost of a home extension, contact BuildTech today.

What size extension can I build without planning permission in Ireland?

In most cases, planning permission is not required before you may make modest alterations to your home. The following are the most common situations in which you may require authorisation from the planning department:

  • Construct an addition that has a floor area of more than 40 square metres (this includes new and any existing extensions)
  • Modify how the land is currently utilised by transforming a garage into a commercial space. This is referred to as a “material change of use.”
