It
often depends also on whether your house has been extended in the past.
Even if you now only want to put a conservatory on the back of your
house, if you have previously had an extension, chances are you will
need planning permission for the conservatory.
Planning Permission under permitted
development rights. You will need to apply for Planning Permission to
extend your property if:
- the volume of the house would
increase by more than 10% or 50m3 (whichever is greater) for
terraced properties.
- the volume of the house would
increase by more than 15% or 70m3 (whichever is greater) for any
other house type
- you live in a conservation area,
National park or Area of Outstanding Natural Beauty
- the extension is closer to any
highway than any part of the original house (a footpath is also
classed as a highway)
- the extension is higher then the
roof of the original house or is over 4m high (pitched roof) or 3m
high (flat roof)
- you are using over half of your
external garden space
- the building is a Listed Building
These are only general rules for when
you will need to apply for Planning Permission, and each project should
be looked at individually. We would always advise seeking written
confirmation that your development does not require Planning Permission
from the local authority
Even if you have had no previous extensions, here are some examples of the type of extensions that in most cases need planning permission, to give you an idea:
-
A dormer window in the roof of your house facing the road;
-
A two story extension;
-
A extension to the front of your house, or to the side if it faces a road.
