If you’re thinking of getting a garage extension built on your house, you might be wondering what the rules and regulations are regarding how high the garage can be built. It’s always a good idea to check with your local council authority before you undertake any construction work. While not all work requires planning permission, it’s better to be safe than to have all that work done only for the council to demand you tear it all down again because you didn’t adhere to legal regulations.

Typically, garages don’t require planning permission, but only if they stay within certain parameters. Here’s a breakdown of everything you need to know about getting a garage built:


Garage Parameters                 

If you build a garage, you won’t need planning permission if the following parameters are met:

  • The garage is used for domestic purposes only.
  • The garage does not contain any sleeping accommodation.
  • The ground area covered by the garage and any other buildings within the boundary of the property, excluding the original house, is not more than half the total area of the property.
  • No part of the garage is in front of the principal or side elevation of the original house that faces onto a road.
  • The maximum height of the garage is 4 metres.
  • The maximum eaves height of the garage is 2.5 metres if it is within 2 metres of the property boundary.
  • No part of the garage is within 3.5 metres of the boundary with a road to the rear of the house.
  • If you live in a house within a World Heritage Site, area of outstanding natural beauty or National Park, the maximum total area of ground covered by buildings situated more than 20 metres from any wall of the house does not exceed 10 square metres.
  • If you live in a house within a conservation area, World Heritage Site, area of outstanding natural beauty or National Park the garage is not situated between the principal or side elevation of the house and its boundary.

So, for the height of a garage, you are limited to a height of 4 metres, and 2.5 metres for the eaves height – eaves height being the edge of the roof overhanging the face of a wall.

As for a minimum size, there are no building regulations in the UK that cover a legal minimum. A good rule of thumb is to ensure the garage is large enough to fit at least one car.

If you wanted a larger extension than these regulations stipulate, then you will need to contact your local council and obtain planning permission before any work begins.
