            NEW PLANNING RULES 

 

July 2015: Proposed changes to planning law:

  • In London, proposals to end to the need for planning permission for upwards extensions for a limited number of storeys up to the height of the adjoining building.
  • A new “zonal” system, as employed in many other countries, which will give automatic planning permission on all suitable brownfield sites, removing unnecessary delays to redevelopment.
  • Power for the government to intervene and have local plans drafted setting out how housing needs will be met when local authorities fail to produce them, and penalties for those that make 50% or fewer planning decisions on time.
  • Stronger compulsory purchase powers to bring forward more brownfield land and devolution of planning powers, including powers over land, to the mayors of London and Manchester.
  • The right for major infrastructure projects that include elements of housing development to be fast-tracked through the Nationally Significant Infrastructure regime.

 

 

In September 2012 the government announced plans to 'consult' on PDF rights being made more genrous for rear extensions.   

EXTENSIONS  and  CONSERVATORIES

You can build certain types of home extension without having to make a planning application -  subject to meeting the rules below. This is known as 'Permitted Development'.

The main difference to the old system is that new extensions are no longer judged in terms of their volume. Instead there are clear rules on their external depth, width and height. But there are still some grey areas, such as defining 'principle elevation' (normally, but not always, the front wall). The rules for conservatories are the same as for extensions.  

If your design doesn't meet the following rules, you can of course apply for planning permission.

 

FRONT EXTENSIONS

No extension allowed in front of your ‘principal elevation’ -  normally the front main wall.

 

SIDE EXTENSIONS

No extension allowed where your side wall faces a highway (or where the side is the ‘principle elevation’). Otherwise:-

Must be single storey

Max height                                  4m

Max width                                    up to half width of original house.

 
REAR EXTENSIONS

Max depth

Single storey ext             4m  for  detached houses  (temporarily doubled to 8m from Sept 2012)

                                                            3m  for attached houses (semis, terraces etc)

                                                                  (temporarily doubled to 6m from Sept 2012)

2 storey or higher            3m   including ground floor   (temporarily doubled to 6m from Sept 2012)

Max height

Single storey ext             4m

 

ALL EXTENSIONS

Height

No extension to be higher than the highest part of the main roof.

Eaves and ridge height = no higher than existing house

Extensions within 2 m of boundary = 3m max eaves height

Garden plot

No extension where more than half the area of land around the ‘original house’ * would be covered by additions or other buildings.

2 storey or higher extensions must be no closer than 7m to the rear boundary.

Design

Roof pitch of extensions higher than one storey to match existing house.

Materials to be similar in appearance to the existing house.

No balconies or verandas

Windows  to upper floors:  side-facing to be obscure-glazed, and 1.7m above floor level

 

CONSERVATION AREAS (and other ‘designated land’*)

No PD for rear extensions of more than one storey.

No side extensions.

No cladding of the exterior.

 

LISTED BUILDINGS

      Not permitted - but you only need make a single application for Listed Building Consent

The TEN YEAR and FOUR YEAR PLANNING RULES

Without the intervention of the Local Planning Authority (LPA) immunity from enforcement action can be acquired after a period of time has elapsed. This is referred to as the Four Year Rule and Ten Year Rule and is applicable as follows:

Ten Years - change of use of land or breach of planning conditions

Four years - development (i.e. building works) that is substantially complete; or the use of a building, or part of a building, as a dwelling house

In most cases if four years have passed since construction, unless the change of use is by itself having an adverse impact, one would hope the authority would not consider it expedient to take action - but that is up to them.

Note that the ‘second bite’ rule allows an LA to take further enforcement action outside the usual four and ten-year limits – provided the LA has already tried to take enforcement action within those initial time limits.
