Planning permission can be a confusing and tricky subject to get right, however we’ve put together a guide on how to make sure you get it right first time, every time.
The rules that govern outbuildings cover log cabins, summer houses, sheds, garages and greenhouses, as well as other kinds of buildings like kennels, ponds, swimming pools and enclosures. It’s important to remember that for any garden building, you build a good, solid base for it to sit on. For information on how to build a base for a garden building, check out our guide on building a base.
Though outbuildings can be built without planning permission, they need to adhere to strict rules governing their existence to be built without planning permission. Garden buildings (gazebos, sheds, log cabins etc.) need to:
- Have only one storey;
- Have eaves (the bottom part of the roof) no higher than 2.5 metres, with the overall maximum height being 4 metres for a dual pitched roof (two sides to the roof) or 3 metres for any other building roof;
- Not have a veranda or balcony (this applies to the house as well);
- Not be on a raised platform higher than 300 millimetres;
- Not have a microwave antenna;
- Not be a separate, self-contained living area
The rules around where you can place a log cabin are also strict. The building must:
- Be at least 2 metres from any boundary if more than 2.5 metres tall (total) or 1 metre from any boundary if lower than 2.5 metres;
- Not be forward of the principal elevation (front wall) of the original house (original house is defined as the house as it was first built or, as it stood on 1st July 1948 if it was built after)
- The building must not take up over 50% of all land around the original house, nor is it allowed to combine with any other outside buildings to take up over 50% of all land around the original house – For example, if there is a shed taking up 30% of the surrounding area of the property and a kennel taking up 15%, planning permission would be required to build a proposed greenhouse taking up 20% of the land around the property. Extensions and conservatories are not considered part of the original house, and so are classed as taking up a portion of the surrounding area as well
Though most people won’t need to consider these, there are specific rules governing the placement of log cabins on designated land, national parks and areas of outstanding natural beauty or near listed buildings. These are:
- If the garden building is on designated land, it must not be at the side of your house;
- If you live in a national parks protected land, the building must not be more than 10 square metres in size if placed more than 20 metres from any wall of your house;
- It must not be within the boundary of a listed building
Planning Permission and working from home
If you plan on working from home in a spare room, extension, log cabin or shed, you don’t usually need planning permission to do so; however there are some rules you need to abide by. Your home needs to:
- Still be primarily used as a private residence;
- Not cause a marked increase in people visiting the house or increase in traffic from visitors;
- Not have deliveries which would disturb neighbours
- Not create excessive noise or smells, particularly during unreasonable hours;
- Not involve things that aren’t usual for a house
Living in a garden building
For many people aged 20-34, house prices and mortgages are making the first rung on the housing ladder much harder to get on. More than 25% of young people still live at home – the highest number since records began in 1996. This can present problems. As adult children come and go at all hours whilst trying to maintain a social life. This needn’t be the case however, as a log cabin can be a great way of helping your child stay at home and keep their privacy.
If you plan on using a garden building as a self-contained living area, you would require planning permission; however this could be a great solution to staying in the house. Sleeping accommodation is not covered by permitted development, and so requires planning permission.
A garden building which is also sleeping accommodation could also be subject to council tax, regardless of whether anyone’s staying in it.
Planning permission can be applied for through the Planning Portal website. Costs vary depending on what kind of work you are proposing and the waiting time to get a decision can be between 8 and 13 weeks. Things taken into consideration include:
- Loss of light or overshadowing;
- Design, appearance and materials;
- Nature conservation;
- Government policy.
Brian has some more top tips to make sure you make the most out of your application:
- Withdrawing an application is pointless and a ‘free go’ is usually available, whether or not the first is withdrawn;
- Don’t trust a builder to know the Permitted Development rules;
- Trees in Conservation Areas are protected: removal must be via consent;
- Talk to the neighbours first, or at least think about the impact of the project on others;
- Use your rights: always appeal a refusal to the Planning Inspectorate. You should also appeal if you have no decision 8 weeks after validity;
- Do two planning applications in parallel if the design challenges Council policy;
- Don’t believe everything council planners say
