Internal & External Works

Can I carry out internal alterations, external repairs and maintenance?

You can carry out any internal alterations you wish as long as you do not alter the domestic use of the house.  External works of repair, maintenance and improvement such as painting or replastering do not need planning permission so long as they do not materially affect the external appearance, thus rendering the appearance inconsistent with neighbouring buildings. You may need approval for certain external alterations e.g, a new connection to a sewer.

This exemption does not apply to buildings listed for preservation in the local development plan or draft development plan nor to the subdivision of a house into flats or granny flats. Planning permission must be obtained for such works.

Can I convert my garage to domestic use?

The conversion for use as part of a dwelling house (e.g. as a living room or bedroom) of a garage, store. shed, etc. attached to the rear or side of a house is normally exempted development, subject to the 40 square metre limit and conditions as set out the "Can I Build an Extension?" Question.

Can I demolish an old building?

You can demolish without permission a building other than-

  • a habitable house, or
  • a protected structure or a proposed protected structure;
  • a building in a terrace or one which is attached to another building in separate ownership.

However, it does not automatically follow that you will get permission to build a replacement.

It also includes a building where the last permitted use was as a house, even if it has been in unauthorised use since.

habitable house includes a structure which was last used as a dwelling even if it is now in an unlivable condition.
