Posted by on 29 August 2013 01:15 PM

Here at Taylors Garden Buildings we have a vast knowledge of all types of garden buildings and the associated planning regulations. This is a short guide to help you understand the vast amount of rules and regulations involved with erecting an outdoor building.

The following should be read only as a guide line to planning permission for log cabinsshedsgaragessummerhousesfencesgates and decking:

As a general rule of thumb to avoid planning permission and building regulations the following applies in most areas of the country:

  • You must not have a garden building forward of the principal elevation fronting a highway.
  • You will need planning permission if your house is in an area of outstanding natural beauty, the broads, national parks or a world heritage site, and the building is more than 20 metres away– if so the building will need to be limited to 10 square metres. it can be quite tricky to work out the area, this volume calculator may help
  • In any of the designated areas above the outbuilding must not be placed on the side of a property.
  • Outbuildings and garages to be single storey with a maximum eaves height of 2.5 metres and an overall height of 4 metres with a dual pitched roof and 3 metres with any other roof style.
  • Verandas, balconies or a Raised platforms must me under 30cm.
  • You cannot employ people within the sectional building.
  • You cannot use it as sleeping quarters for instance a spare bedroom
  • You cannot supply a water source or toilets to the building.
  • The maximum height must be 2.5 metres when within two metres of a boundary.
  • You house cannot be classed as a listed building. If so you will require planning permission.
  • The outbuilding must not cover more than half the area of land around the original house. The term 'original house' means the house as it was first built without any extensions etc. Extension rules do not apply if built before 1st July 1948.
  • With a carport attached to the house it cannot exceed 30 square metres in floor area before it requires building regulations.
  • With a detached garage it cannot exceed 30 square metres in floor area before it requires building regulations. An attached garage will normally require building regulations.
  • To avoid building regulations for a garden building between 15 and 30 square metres, it must be positioned at least 1 metre from any boundary or is not constructed of substantially non-combustible materials. Building regulations will not normally apply if the floor area is less than 15 square metres.

If your garden building does not comply with any of these rules it is likely you will require planning permission/building regulations.

The following is a guideline for planning permission for decking, fences, gates and garden walls. To avoid planning permission you need to follow the following guidelines.

  • If next to a highway used by vehicles or the footpath or such a highway it cannot exceed 1m high. (2m high elsewhere)
  • You house cannot be a listed building or in the curtilage of a listed building.
  • The fence, gate or wall or any boundary involved cannot form a boundary with a neighbouring listed building or its curtilage.
  • To take down, alter or improve an existing structure you cannot add to its height. (In a conservation are you may need consent to take down a fence)
  • The decking must not be more than 30cm above the ground.
  • Together with any other garden buildings/extensions, the decking must not cover more than 50 % of the garden area.
  • Building regulations usually apply to every deck structure requiring planning permission.

If you are in any doubt please do contact your local planning office especially if you are living in an area of outstanding natural beauty, the broads, national parks or a world heritage site, you may also need planning permission if your house is registered as listed.

All of the above is accurate as of 1st October 2008  however things do change as we well know, you may have local restrictions, you’re property deed may restrict certain things, if you are at all uncertain, or require further clarification then please contact your local planning office – it only takes a quick call for peace of mind.

I hope you find this small article useful, we have a condensed version on the site which may also be useful in our FAQ section on planning permission for Garden Buildings at Taylors.
