Advice for planning a shed


Sheds are classed as outbuildings and are considered to be permitted development, see the government planning portal. This means they do not generally need planning permission, subject to a few important provisos:

  • The shed should not be sited forward of the front elevation of the original house.
  • Outbuildings must be single storey with a maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  • If the building is within 2 metres of the property boundary it must not exceed 2.5 metres in total height.
  • Any outbuilding within the curtilage of listed buildings will require planning permission.
  • Further rules apply In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage sites

As standard, our sheds are just under 2.5 metres in height and therefore may be placed anywhere within your back garden. We’re happy to build taller garden buildings with appropriate planning permissions.

If you live in a conservation area, listed building or require permission for a taller building, please do not hesitate to get in touch. We can assist you through the planning process or for a nominal fee, apply on your behalf.


Timber is a natural product which will contract and expand in response to atmospheric conditions so it is very important to provide a solid, level and smooth base to minimise movement.

We recommend two options:

  • 100mm thick, solid concrete base.
  • Swift Foundations Eco Base. This is a clever system of interlocking plastic grids laid over a membrane and filled with shingle. It has advantages over concrete in terms of cost, speed and ease of construction. Made from recycled material this is the eco friendly alternative. We are pleased to stock this product.

Alternatively, the shed can be placed upon solid, level paving slabs.
