Do I Need Planning Permission for a Shed or Outbuilding?

Friday, August 17th, 2012

You might assume that you don’t need permission to install a simple garden shed or garage, but there are occasions when planning permission or building regulations are required. planning permission for sheds and outbuildings

‘Outbuildings’ are structures such as sheds, greenhouses and garages. The rules also apply to installations such as swimming pools, ponds, sauna cabins, kennels and tennis courts. Outbuildings are allowed without planning permission subject to the following limits and conditions:

  1. No outbuilding can be closer to the road than the part of the original house nearest to the road or any point 20m from the road (whichever is nearest).
  2. Outbuildings and garages should be less than 4m in height with a ridged roof, or 3m otherwise.
  3. No more than half the area of land around the original house is to be covered by additions or other buildings.
  4. If the outbuilding is greater than 10 cubic metres in size and is within 5m of a house, it is considered an extension, not an outbuilding.
  5. In National Parks, Areas of Outstanding Natural Beauty, conservation areas and within the area immediately surrounding a listed building, the cubic content of the building should not be bigger than 10m³.

The term “original house” refers to the house as it was first built or as it stood on 1 July 1948, if built before that date. These rules apply only to houses and not to flats, maisonettes or other buildings.

On occasion, building regulations might apply instead of planning permission. It’s advisable to get advice from your local planning authority before you start a project just to be on the safe side by visiting

With Garden space becoming more valuable for families with children and loft conversions some times impractical, converting your cellar or basement in to some extra living space is definitely worth considering.

With our expertise, here at Derwood Homes and Developments we help home owners who would like to convert their basement into some extra special living space to carefully plan and consider all of the costs implications before they start the project.

What to Look Out For When Converting A Basement

Basement conversions are very often prone to damp and require careful planning to ensure that all of the engineering works needed to convert a basement are carefully considered to determine what impact overcoming such problems may have on the conversion costs. That said it is not as complicated as it may sound.

Employing the right company to carry out a basement conversion is highly recommended as they will carry out a thorough survey and address all of structural and damp challenges that your basement converting a cellar using basement wall tankingconverison may need.

Some basement and cellar conversions need what is known as ‘under pinning’ works to be carried out and is something you shouldn’t attempt to do yourself as this involves excavating under the house foundations to be able to dig down into the ground to stabilise the house structure whilst at the same time to increase the head height of the inside of the basement .

Dealing with any damp or water ingress within the basement is tackled by installing a special cavity wall membrane to the basement walls that drains the damp or water down into drainage channels that are installed around the perimeter of the internal walls.

This system is then connected to a unique underground sump that is fitted with a submersible pump that pumps of any such water out of the basement to the outside house drainage system to ensure that your basement conversion is kept dry providing a pleasurable cellar conversion for you and your family to enjoy.basement conversion drainage systems

The same principle is applied to the basement floor which is then connected to the newly installed wall drainage system and sealed to create a type of self contained envelope throughout the whole cellar converison. Once this tanking procedure is completed timber frame studding is then constructed in front of all of the walls, insulated and lined with plaster boards and plastered ready for decorating. For the expert it is an excellent way towards converting your basement into some extra living space.

With Building Regulations and House Insurances tightening their policies and procedures, it is wise to ensure that any building work that is carried out on your home is done so in full compliance and inspected and certified by a qualified engineer.
