Summary of Current PD Rights Extended PD Rights Restricted PD Rights /
Approach in Sensitive Areas
Part 8, Class A permits the extension
or alteration of an industrial building or
a warehouse. Development is not
permitted if the floorspace of the
original building is exceeded by more
than 750 sq m or the cubic content of
the original building is exceeded by
more than 20%. This right is subject to
certain other conditions regarding the
buildings use; the extension’s height;
its external appearance; proximity to
the premises curtilage; whether the
developments’ premises adjoins the
curtilage of a dwellinghouse or flat; its
impact on parking spaces or turning
areas; location in the conservation
area, AONB or National Park and the
time of day its to be used.
Revised Part 8 – Industrial, research/development &
storage uses
Permitting a maximum of 1,000 sq m floorspace for
extensions and alterations per building (500 sq m in
AONBs, CAs & National Parks, 250 sq m in
floodplains) and up to max of 25 per cent extra
floorspace;
Height no greater than existing building, if within 10m
of a boundary max height of 5m;
A maximum floorspace of 100 sq m per new building;
Not within 5m of a boundary or facing a highway;
Materials to match existing building;
Not within 10m of a boundary of a residential property;
Not permitted development within the curtilage of a
Listed Building unless Listed Building Consent for the
development has previously been granted;
Max 50 per cent ground coverage;
Permeable (or porous) hardstanding up to 100 sq m
(impermeable (or non-porous) where risk of
contamination); and
No basements in floodplains.
Delete the test of ‘material effect on external appearance’,
and replace with a test similar to that for householder
development. This takes into account development facing a
highway and distance from boundary (as used in revised
Part 8).
Extended Part 8 PD rights are to be
provided in Conservation Areas
(CAs), Areas of Outstanding Natural
Beauty (AONBs) & National Parks
(NPs) up to a restrained floorspace
limit of 500 sq m. Further they are
permitted up to a floorspace of 250 sq
m on floodplains.
Development and excavation on sites
of natural, archaeological or
geological value offers the potential to
destroy such characteristics and
therefore conditions to take away PD
rights in ASSIs & SAIs are proposed
for Class A of Part 8 (permitting
extensions, alterations & new build).
Specifically exclude incineration
operations from Part 8 rights – only
large scale incineration processes
should be excluded.
