Do I Need Planning Permission?

Outbuildings are considered to be permitted development, which means you will not need an application for planning permission, provided all the conditions are met. The rules governing outbuildings, which apply to sheds, are:-

Designated Land

Designated land is land which is part of a conservation area, National Parks and Areas of Outstanding Natural Beauty. Outbuildings to the side of the house are not permitted 

Listed Buildings

Outbuildings are not permitted within the grounds of a listed building

National Parks, Heritage Sites and other Areas of Outstanding Natural Beauty

In these areas, the outbuilding must be 20 metres from any wall of the house, and the total area of the outbuilding must not exceed 10 square metres for it to be allowed.

Outbuildings are not permitted forward of the main front wall of the house.

Outbuildings and other additions must not exceed 50% of the total area of land around the original house. Any previous extensions must be included when calculating this 50% limit.

For this to be allowed, any new building must not be for self-contained living accommodation.

Outbuildings must be a single storey with a maximum eaves [overhanging lower edge of roof] height of 2.5 metres and maximum overall height of 4.0 metres with apex [highest part especially when forming a point] roof, or 3.0 metres in any other case.

If the outbuilding is within 2 metres of the property boundary, the whole building should not exceed 2.5 metres in height.

This is a guide only. Policy throughout the UK may vary. You should check with your Local Planning Authority whether permitted development rights apply - they may have been removed.
