Planning Permission for Conservatories

In this chapter we will discuss planning permission for conservatories and how it affects both houses and maisonettes alike.

Planning Permission for Conservatories

Local authorities planning requirements for conservatories.

Home improvement is the principal growth area in our economy these days. We are all having conservatories, bathrooms and kitchens extensions built onto our properties due our disposable income and low interest rates.

To police these developments; planning requirements are getting strict to ensure that any development is in keeping with the surrounding houses and neighbourhood. 'Nobody would wish to live next to an eyesore.

Approximately 60% of conservatories built will require planning permission.

You may not need planning permission as long as you meet with the following requirements.

Detached Properties

You are approved to extend up to 70m3 or 115% of the total area of your property whichever is larger. Please note this is a combination of the total amount of extensions, i.e. if you have had a bathroom extension of 35m3 and whish to have a conservatory of 41m3 the total would be74m3 therefore planning permission would be necessary . However, if the total was less than 70m3, or 115% of the volume of the property, planning permission may not be required.

Semi-Detached Properties

The same as detached properties, you are allowed to develop up to 70m³ or 115% of the total area of your property.

Terraced or End of Terrace Houses or Bungalows

Same as detached and semi-detached, but only 50m³ is allowed to be developed.

Flats or Maisonettes

This type of property has no permitted development rights and in all cases planning permission will apply, there are no exceptions.

The above mentioned only applies to extensions after the 1 July 1948.

We have listed some additional information and conditions which attract planning permission:

1. If you develop within 2m of your boundary and the highest point at that intersection is 4m or more high.
2. If the total conservatory area covers more than 50% of the original land.
3. If you’re development rights have been removed.
4. Grade II listed buildings. Special conditions apply the local authority may require hardwood with a glass roof.
5. Where a conservatory is 20m or less from a road or public footpath. (see sketch A)

Sketch A Irrespective of the size of the conservatory, should the distance between points A and B be less than 20m planning permission may be required. Shaded Area may be any of the following: Road Highway Motorway Public Foot Path Bridal Way Access to another property Access to other garage

Impact to the Boundary

The planning officers will look at the projection of the conservatory i.e. how far it will protrude into the garden, as a rule they are content at around 3m projection from the original property not from an extension Should the proposed development extend more than 3m They may not look at it sympathetically and ask for it to be reduced in size. The reason for this is so your neighbour does not have to look at a large brick wall more than 3m long. Hence the term impact onto the boundary.

To overcome this you may wish to include a facet to your conservatory which may help in some situations. (see sketch B) This should be done by your supplier as a matter of course.

Sketch B You can see from this drawing that the total impact onto the boundary is 6m and you could expect the planning office to refuse your application.

If planning permission is not mandatory a letter of lawful development from the council is always a good to obtain. As when you sell your property in the future, your have evidence that you have complied.

However, we strongly advise, if you are uncertain always ask your local planning officer. You will find they are very helpful and they will give you the correct advice so no mistakes are made.

If you are considering a conservatory in excess of 30m² you will need conservatory building regulation approval please follow this link to conservatory building regulations.
