Planning Permission Guide - Log Cabins
Do I Need Planning Permission for a Log Cabin?
In many cases, a log cabin can be installed in your garden without applying for planning permission because it may fall within permitted development rights. However, your log cabin must meet certain limits and conditions relating to its size, height, position and intended use.
This guide provides a general overview of the planning rules for log cabins and other garden buildings in England. Planning rules may differ elsewhere in the UK, and additional restrictions can apply to individual properties and locations.

What Is Permitted Development?
Permitted development rights allow certain types of building work to be carried out without making a planning application, provided all the relevant limits and conditions are met.
For planning purposes, a log cabin used for a purpose incidental to the enjoyment of your home may be treated as an outbuilding. The same general permitted development rules therefore apply to log cabins as they do to sheds, summer houses and other garden buildings.
Permitted development rights do not cover separate self-contained living accommodation, and different requirements may apply if your log cabin will be used for purposes beyond normal domestic use.
Log Cabin Planning Permission Rules
For a log cabin to qualify as permitted development in England, a number of limits and conditions apply. Some of the main points to consider include:
- The log cabin must not be positioned on land forward of a wall forming the principal elevation of the original house.
- The building must be single storey.
- The maximum eaves height is 2.5 metres.
- The maximum overall height is 4 metres for a log cabin with a dual-pitched roof, or 3 metres for any other roof.
- If any part of the log cabin is within 2 metres of a property boundary, the maximum overall height is 2.5 metres.
- No more than half the area of land around the original house can be covered by additions or other buildings.
- Additional restrictions apply on designated land, including National Parks, conservation areas and other protected locations.
- Outbuildings within the grounds of a listed building require planning permission.
These are general guidelines only. Always check the current Planning Portal guidance and contact your local planning authority if you are unsure whether your proposed log cabin requires planning permission.
How Close Can a Log Cabin Be to a Boundary?
A log cabin can potentially be positioned within 2 metres of a property boundary under permitted development, but its maximum overall height must not exceed 2.5 metres.
If the building is more than 2 metres from the boundary, the general maximum height limits are 4 metres for a dual-pitched roof and 3 metres for other roof types, with a maximum eaves height of 2.5 metres.
This makes the position of your log cabin particularly important when choosing a model. Check both the overall height and eaves height shown on the individual product page before deciding where the building will be installed.
How Big Can a Log Cabin Be Without Planning Permission?
There isn't a single maximum floor size that applies to every log cabin. Instead, permitted development considers factors including the building's height, position and the amount of land around the original house already covered by additions and other buildings.
Under the permitted development rules, no more than half of the land around the original house can be covered by additions or other buildings. The term "original house" generally refers to the house as it was first built or as it stood on 1 July 1948 if it was built before that date.

Can I Use a Log Cabin as Living Accommodation?
Permitted development rights for outbuildings do not cover the use of a log cabin as separate, self-contained living accommodation. If you intend to use your log cabin as independent residential accommodation or for sleeping, you should seek advice from your local planning authority before proceeding.
Can I Use a Log Cabin as a Garden Office?
Using a log cabin as a home office does not automatically mean planning permission is required. However, the nature and scale of its use can be important. If the building will be used primarily for business purposes, regularly receive customers or visitors, or create additional noise, traffic or other impacts, you should seek advice from your local planning authority.
Log Cabins on Designated Land and Listed Properties
Additional restrictions apply to outbuildings on designated land. This can include conservation areas, National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites. There are also additional requirements for listed buildings.
If your property is in a protected area or is a listed building, check with your local planning authority before ordering or installing a log cabin.
Building Regulations for Log Cabins
Planning permission and Building Regulations are separate requirements. A small detached garden building with a floor area of less than 15 square metres will not normally require Building Regulations approval if it does not contain sleeping accommodation.
For detached buildings with a floor area between 15 and 30 square metres, Building Regulations approval will not normally be required if the building contains no sleeping accommodation and is either at least one metre from a boundary or constructed substantially from non-combustible materials.
Different requirements may apply depending on the size, construction and intended use of your log cabin. Check the current Planning Portal guidance before proceeding.
Check Before Ordering Your Log Cabin
Before choosing your log cabin, consider its dimensions, overall height, eaves height, intended use and position within your garden. You can then compare these details with the current permitted development requirements.
This guide is provided for general information only and should not be treated as planning or legal advice. It is your responsibility to ensure that your proposed log cabin complies with the applicable requirements. If you are unsure, contact your local planning authority before ordering or installing your building.
