House and Extension Plans at 77 Camden Street Lower, Dublin, Ireland.

Extensions

Any extension to the rear of your property over 40 square meters requires planning permission. 

The floor area of any extension above ground level must not exceed:

  • 12 square meters for terraced or semi-detached houses
  • 20 square meters for detached houses

Also, any extension above ground level must be at least 2
meters from any boundary.

Any extension must not reduce the open space at the back of the house (that is used only by the people who live in the house) to less than 25 square metres.

There are also detailed rules about:

  • The height and roof profile of an extension
  • Where the windows are placed in an extension.

Here are some answers to commonly asked questions:

 

What are the rules regarding the height and roof of an extension?

  • Any extension cannot exceed the height of the existing house
  • if the rear wall of the house does not include a
    gable, the height of the walls of the extension must
    not exceed the height of the rear wall of the house;
  • if the rear wall of the existing house has a gable, the
    walls of the extension (excluding any gable being
    built as part of the extension) shall not be higher
    than the side walls of the house;
  • in the case of a flat roofed extension, the height of
    the highest part of the roof may not exceed the
    height of the eaves or parapet. In any other case, no
    part of the new roof may exceed the highest part of
    the roof of the house.
  • any windows proposed at ground floor level as part
    of an extension should not be less than 1 metre
    from the boundary they face;
     any windows proposed at above ground level should
    be not less than 11 metres from the boundary they
    face;
  • The roof of any such extension should not be used
    as a balcony or roof garden.

What are the rules regarding new windows?

  • Any windows proposed at ground floor level as part
    of an extension should not be less than 1 metre
    from the boundary they face;
  • Any windows proposed at above ground level should
    be not less than 11 metres from the boundary they
    face.

Can I install a solar panel? 

  • Yes. Recently, the governmnet passed planning legislation which allows for the installation of solar without planning permission. 

Can I build a front porch?

  • You can build a porch without planning permission, as
    long as it does not exceed 2 square metres in area and is
    more than 2 metres from any public road or footpath.
    Where the porch has a tiled or slated pitched roof, it must
    not exceed 4 metres in height, of 3 metres for any other
    roof type. A front porch within these limits is the only
    type of development allowed to extend beyond the front
    wall of the building (the building line) and still remain
    exempted.

What about walls, fences and gates?

  • Capped walls made of brick, stone or block with a
    decorative finish, railings and wooden fences, but not a
    metal palisade or security fences, can be erected without planning permission as long
    as they do not exceed 1.2 metres in height in front of your
    house or 2 metres at the side or rear. If the wall is made
    of plain blocks or mass concrete, it must be rendered or
    plastered. Gates and gateways may be built or replaced
    providing they do not exceed 2 metres in height. You will
    need planning permission if you wish to make a new or
    wider vehicular access to the public road. 

It is extremely important to check if you need planning permission before you start building an extension. If you do not get planning permission when it is needed, you may have to pay a large fine.
