Planning permission needed for a conservatory:

In almost every case you will not need to worry about getting permission from your local authority before you install your baltic pine conservatory.

Under present legislation, you will NOT need to apply if:

1.) Detached and semi-detached houses
The conservatory does not increase the overall volume of the original house by whichever is the greater - 70 cubic metres or 15% of the volume up to a maximum of 115 cubic metres. (Scotland has its own regulations on this.)

1a.) Terraced or end-of-terraced houses
The conservatory does not increase the overall volume of the original house by whichever is the greater - 50 cubic metres or 10% of the volume up to a maximum of 115 cubic metres.

The wording 'original house' means the house as it was first built or as it stood on 1st July 1948 if it was built before then. If extensions have been built since, then those extensions count against the allowance.

2.) No part of the conservatory projects further forward than the existing front wall or higher than the highest point of your roof line.

3.) No part of your conservatory comes within 2 metres of your boundary if its more than 4 metres above the ground.

4.) It does not cover more than half of the original garden area.

Neither can it be used as a separate, independent dwelling.

Designers can always provide you with more detailed advice on any aspect of this and, should planning permission be required, guide you through the process. Permission would always be required if your house is a listed building or a conservation area. Should there be any doubts please contact your local planning authority.
