Does your new conservatory need planning permission?

A Planning application will be required if the new conservatory exceeds any of the following:

No more than half the land area around the 'original house'* would be covered by extensions or          other outbuildings.

No conservatory forward of the principal elevation or side elevation fronting towards a highway,          a highway would include public footpaths and roads

A single-storey rear conservatory must not extend beyond the rear wall of the 'original house'*              by more than 3 metres (semi-detached/terrace house) and 4 metres for a detached house.

The maximum height of the new conservatory is 4 metres. This would mean any part of the                  conservatory including the ridge.

There is no conservatory to be higher than the highest part of the original house roof.

The maximum eaves height of a conservatory within 2 metres of the boundary of 3 metres high.
The roof pitch of a conservatory is higher than one storey to match the existing house.

A new conservatory to be single-storey with a maximum height of 4 metres and width no more            than half that of the original house.
