Do I need permission for my industrial or warehouse building?

Certain extensions or new buildings within existing industrial or warehouse sites qualify as ‘permitted development’ and so do not require planning permission.

There are some variations between England, Wales and Scotland:

• In England, a detached building with floorspace above 200 sq.m. (measured externally) will always need permission, whereas in Wales the limit is 100 sq.m.
• In Scotland, all free-standing buildings need permission, whereas some extensions do not.
• Additional restrictions include a bar on building within 5 metres of a site boundary and where there would be a loss of a parking or turning area.

Exceeding the size limits or breaching these restrictions will mean that you will need to make a planning application.

However, there are also other reasons why permission may be required. Note that we always recommend that you obtain professional advice in any individual case.
