Rules governing outbuildings apply to sheds, greenhouses and in our case garages.
Garages and any other 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 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 dwellinghouse.
• 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.
• Within the curtilage of listed buildings any outbuilding will require planning permission.
If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.
If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed of substantially non-combustible materials.
Building a new garage attached to an existing home would normally need building regulations approval.
