Garages and Outbuildings

Bishop Ltd will build your garage or outbuilding and ensure that it is internally sealed to prevent damage from the elements to anything inside.

Garages can be either attached to or detached from an existing property, outbuildings are generally detached. Clients will receive advice as to when building and planning approvals are required and on practical matters concerning the space where we think it would benefit the overall finish and practical use of the building.

As a rule of thumb, garages and outbuildings are considered to be permitted development and do not require 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. 

However, building regulations will still apply to structures covered by permitted development.
When building a garage or outbuilding, amongst other things, it would be advisable to consider the following factors:

  • If the new building is attached to the existing property would you prefer to be able to enter the house from it? If so where would the entry point be, utility room or kitchen maybe?
  • Would it be viable to create an office/room in the roof of the new garage or outbuilding? It would be most cost effective to add this room whilst the main garage or outbuilding is being built.
  • DON'T forget to get the look!
    If you do not want the new garage or outbuilding to stick out like a sore thumb then it is advisable to always match the new materials (and design) as closely as possible with the materials used on the existing building. The old and new should integrate seamlessly by using, for example, the same roof tiles, windows, entry doors and trims.

Please see our Planning Permissions page for helpful guides on when planning permission is required for outbuildings and other building works.
