Are You Allowed To Put Your New Garden Office Where You Want It?

Once you have decided to purchase a new JUST Garden Office it is very important to make sure you comply with all the necessary planning rules and building regulations.

Whilst you may be somewhat preoccupied with decided the best place to put your new garden office in your outside space, it is very IMPORTANT to ensure that you are allowed to put the garden office where you want it to be located.

Planning Permission & Permitted Development Guidelines

With all building works, the owner of the property (or land) in question is ultimately responsible for complying with the relevant planning rules and building regulations (regardless of the need to apply for planning permission and/or building regulations approval or not).

The general advice is to always discuss your proposals with the relevant Local Planning Authority and Building Control Service before starting work.

Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions:

  • No outbuilding on land forward of a wall forming the principal elevation.
  • Outbuildings and garages to be single storey with 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.
  • Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwelling house.
  • No verandas, balconies or raised platforms.
  • No more than half the area of land around the "original house"* would be covered by additions or other buildings.
  • In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by buildings, enclosures, containers and pools more than 20 metres from house to be limited to 10 square metres.
  • On designated land* buildings, enclosures, containers and pools at the side of properties will require planning permission.
  • Within the curtilage of listed buildings any outbuilding will require planning permission.

* The term "original house" means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

* Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.

Please note: The permitted development allowances described here apply to houses not flats, maisonettes or other buildings

Building Regulation Guidelines

The Building Regulations are made up of procedural and technical provisions. Small detached buildings are exempt from building regulations provided it is:

A detached single storey building, having a floor area which does not exceed 30m2, which contains no sleeping accommodation and is a building no point of which is less than one metre from the boundary of its curtilage.

JUST Garden Offices

All JUST Garden Offices have been specifically designed to meet the requirements of the current planning permission permitted development rules and building regulation requirements.

Our garden offices comply with the 2.5m maximum height requirements. Garden offices up to 15m2 internal floor area (5m x 3m) are installed 0.5m from any boundary.

For construction purposes the fitting teams require a minimum of 0.5m around the garden office. Garden offices over 15m2 internal floor area (6m x 3m) and up to 30m2 (8m x 4m) internal floor area are installed 1m from any boundary.
