There is a perception amongst most folk that every house is allowed a certain
percentage of extension development without the need for formal Planning
Permission. People seem to think that it applies to them even when they purchase
an already extended property.
The Permitted development allowances as contained within the GPDO 1995, Statutory
instrument 1995 No. 418 is a minefield of criteria and restrictions with
affecting paragraphs and clarifications all over the document which has lead
to a vast array of interpretations from homeowners, agents and Planning
Authorities, some of which has been challenged in the courts. It is so cumbersome
that there is even a government discussion document out at the moment seeking
to address these issues that should result in an update or complete new
legislation document in the coming months so watch this space.
This News Letter is far too short to go into every issue of what you can
and cannot build within the curtilage of a dwelling house without formal
Planning Permission (unless you have purchased my MAXIMUM BUILD PLANNING
GUIDE OF COURSE???) but it may be advantageous to subscribers of this news
letter to highlight some of the more common 'trip up' clauses that will prevent
you from erecting your extension, outbuilding or alterations to your property
as follows:-
1. Site zoning - if your property is within a conservation area or Area of
outstanding natural Beauty or a National park then your PD limits may be
fully withdrawn or limited from normal.
2. New dwellings - If your property was part of an estate, small infill
development, one off build etc. within the last 15 years then there is a
good chance that the Planners cleverly by stealth removed the PD rights to
the property as part of the original Planning Approval as a Planning Condition.
This is to maintain control over your property in most aspects for the future.
Even older housing estates may have their PD rights lifted so do check first.
This is the most common of all reasons why most ordinary householder hopes
are dashed at the outset or illegal buildings are erected in the first place.
3. Previously extended properties - If you are purchasing a property that
has already been extended then it is likely that no further PD rights exist
applicable to extending a dwelling. 70 cubic metres is not a great deal of
extension volume.
4. Ancillary outbuildings - These have minimum distance requirements from
the house and to a highway. They also have strict ridge and Flat roof heights
and are again affected by the sites zoning as in item 1 above. The use must
also be ancillary and contain no bed space. So no granny annexes, office
suites or huge buildings that cannot be classified as an 'ancillary use'.
5. Extension heights - If it is over 4M high within 2M of a boundary then
sorry but no go here as well.
6. Fence heights - Normally 1M max. close to a highway or 2M in most other
cases.
7. Roof Dormers - if they exceed the existing ridge line, front towards a
highway (that means paths as well) or are greater than 40/50 cubic metres
(terrace/other) or within a conservation area then no go for building them
without Planning.
8. Porches - that do not cover a doorway or exceed 3 square metres or exceed
3M high or are within 2 Metres to a highway do not comply with PD - you will
need Planning Permission.
There are more areas of 'trip ups' but the ones listed above are the main
common catches that most people fall into from time to time.
The solution is to always check the constraining details with your local
Planning Dept. with what you want to do and get it 'informally' agreed in
writing. This aspect is actually harder to obtain than you think as most
Councils now want you to apply for a Certificate of Lawfulness (C of E) which
is a legally binding document that confirms (or denies) that you do not require
formal Planning Approval for your scheme.
You see the council have an unfair 'get out of jail free' card where their
'opinion letters' outside of a C of E are not legally binding? - Isn't that
great! Can you imagine what the world would become if we were are all granted
that sort of 'cop out' licence in our correspondence and professional opinions?
Cynical I may be but this sort of evasion of duty and responsibility really
guiles me. The down side is when applying for a C of E is that you need proper
drawings showing all aspects of the design, siting and location plan etc.
which is not normally achievable in a DIY format by the householder, you
need to pay a fee (currently £55.00) and surprise, surprise - it takes
about 2 months!!!! to decide. - ere.......excuse me....but doesn't that sound
just like a Planning application - YES - to be informed that you don't need
planning in the first place! - what a great ploy and clever thinking by the
boys at Whitehall. I think the phrase is....'you couldn't possibly make this
up!
If you have trouble deciding what you want to build is PD or not and the
council remain unhelpful outside of a C of E then do seek a professional
opinion from a Building Design Agent used to this sort of residential
development.
