Permitted Development
Rights
Permitted Development Rights deal with forms
of development that do not necessarily require planning permission. Although there
are various forms of PDR's covering different classes of land use, from a domestic
point of view they generally refer to minor extension work provided certain conditions
are met.
Generally speaking you will need to apply for
planning permission if you can say yes to any of the following:-
- Will the proposed extension
be nearer to a highway than the nearest part of the "original house"?
Note that the "original house" means the house as originally built,
or as it was on the 1st July 1948. Previous owners may have already altered the
house. Also note that the highway includes all public roads, footpaths, bridleways
and byways.
- Will more than half the
area of land around the 'original house' be covered by additions or other buildings?
- Will the extension be
higher than the highest part of the roof to the 'original house'?
- Will the extension be
more than 4 metres in height (measured from the highest ground level position
beside the extension)?
- Will any part of the
proposed extension be nearer than 2 metres to a boundary of the property?
- Will the volume of the
'original house' be increased by more than 10% or 50 cubic metres (whichever is
greater)? Note that this must be calculated by using external measurements
for the proposed extension. Volume calculations may also include the volume of
other buildings (such as garages or sheds) if they are within 5 metres of the
proposed extension and belong to the house. Similarly, the volume calculations
must take account of any building which has been added to the property, that is
more than 10 cubic metres in volume and which is within 5 metres of the house.
- Is the existing property
a Listed Building?

- Is the property fully
or partially situated in a Conservation Area?
Please also bear in mind that Local Authorities can remove permitted development
rights by agreement. This is sometimes done as part of the planning consent process
and therefore the planning history of the land must be considered.
Finally, even though you will not require Planning
Permission if you fall into one of the above categories, Building Control Approval
may still be necessary.
