Section
B - Full Planning Permission |
|
|
|
1. |
|
For developments
that are outside the scope of 'Permitted Development' it is usual
to apply to the Local Authority planning department for full
planning approval. |
|
|
|
2. |
|
This is
normally always required for two storey extensions. |
|
|
|
3. |
|
In some
areas, two storey extensions may only be allowed at the side
of a property but this depends on local conditions and the Unitary
Plan for the area concerned. |
|
|
|
4. |
|
Rear extensions
should preferably be single storey, to avoid overlooking and
privacy issues and usually they may have either a flat or pitched
roof or both in combination. |
|
|
|
5. |
|
Two storey
extensions should normally have a pitched roof with slates or
tiles to match the existing house. |
|
|
|
6. |
|
Restrictions
apply on the size of an extension and its projections from the
line of the original building but these are flexible within 'High
Quality Design' parameters. |
|
|
|
7. |
|
Usually,
the side ground floor extension should be set back 225mm (9 inches)
from the front of the house. If a porch exists the proposed extension
may line through with the porch. If a bay window exists the extension
may line through to form a new porch level with the bay. |
|
|
|
8. |
|
On homes
in close proximity to adjacent properties, the first floor front
should be set back from the front of the house to provide a visual
break. This also results in the roofline at the ridge being lower
than the original house so the extension does not dominate. This
requirement varies depending on the Local Authority and siting. |
|
|
|
9. |
|
Some Local
Authorities require a gap between the side boundary and the first
floor extension of between one and three metres, especially on
corner plots. In some cases this may make the upper storey extension
too narrow to be practical. |
|
|
|
10. |
|
A two-storey
side and single storey rear extension can be combined in one
development. |
|
|
|
11. |
|
Drawings
must accompany the application. It is usual to provide floor
plans at each level to be extended and elevations of the front,
side and rear. These should be drawn for both the original 'as
built' situation and the 'as proposed'. A site location plan
is required and also a block plan showing the relationship of
the proposals to the surrounding properties. |
|
|
|
12. |
|
Planning
applications usually takes from six to eight weeks to be approved. |
|
|
|
13. |
|
Most Local
Authority planning departments now require the site location
plan to be marked on an up to date Ordinance Survey map extract. |
|
|
|
14. |
|
It should
be stated that each Local Authority has its own preferences and
approval of a proposal usually depends on good design, which
takes into account the general street scene, privacy rights of
neighbours, lighting and other additional rules which may apply
to Green Belt, Conservation Areas or Areas of Outstanding Natural
Beauty. For larger or unusual projects it is best to involve
the planning department at an early stage to agree basic principals
before getting too far into the design. |
