Planning Permission in Republic of Ireland

What is the most asked question of the year? You might guess: – “Does my log cabin need planning permission?” The quick answer to that would be – it might.

Ireland’s planning system was introduced on the 1 October 1964, when the Local Government (Planning and Development) Act, 1963 came into effect.  Good news is that if you are planning to build small log cabin at the back of your house you can go as big as up to 25 sq meters as free standing structure. Buildings that can be erected witlhout planning (subject to planning regs) are; non habitable garden houses – max 25 sq meters (270 sq ft) and extensions to buildings not previously extended – max 40 square meters (430 sq ft).

All bigger permanent dwellings needs planning permission. Our log houses are built on timer frame and block pad foundation and do not classify as permanent structure however if you decide to go for bigger log cabin we would advise you to check with your local council regarding the planning permission.

Main reasons of refusals are known to be visual impact, area of high amenity or outstanding beauty, one off housing and sporadic development contrary to the County Development Plan. If you already own a home it will be more difficult.

Ireland is also one of the few European countries that has an independent third party planning appeals system. It is operated by An Bord Pleanála, (the Planning Appeals Board). If you are refused the planning permission for the Log Cabin or Log House we strongly recocmmend to contact “An Bord Pleanala” and appeal the decision. An Bord Pleanala recently overturned a refusal by Carlow Planning Authority. Their report stated ” I consider that the Planning Authority’s decision in this case represents an undue bias against log house construction and versatility and innovation in the evolution of ‘new’ construction materials in the Irish context.”

      Dear Patrick,

      As this cabin is above 25sq meters it would generally need the planning permission. You mentioned its not on concrete base so it doesn’t qualify as permanent structure so it would fall in to the grey area of the planning permission requirements in our opinion.

    Hi. What about connecting electricity and septic? I’m thinking wind and maybe solar. Any idea if that impacts needing planning permission or not? ( Less than 25sqm).

      Dear Tristan,
      In our opinion you can do all above with no planning permission. However if you will live in that cabin it will be classified as residential and would require planning permission. You can use it as office with bathroom no problem.

    Hi I’m thinking of a small cabin extension connected to the side of my semi-d in South Dublin Co.Co. area. Footprint of approx. 14sqm only. Lean to roof from gable of house and connecting door to house in gable. Do you think this will need planning permission? Intended use as a kids playroom. Appreciate any feedback thanks.

      Dear Mike,

      Was the house extended before? If no you wouldn’t need planning permission to our knowledge.
