Frequently Asked Questions About Our Garden Rooms 

Garden rooms are fantastic alternatives to extensions or conservatories and can be purpose-built to your requirements. They're an ideal solution if you're after more space, but don't want to up sticks and move house.

All garden rooms are subject to permitted development rules. Fortunately, more often than not you won't need planning permission for your dream garden building.

Where you'll position your garden room, what size of room you require and its intended use will all affect whether or not you'll need to seek planning permission.

It's also crucial that you take the time to understand which building regulations you must adhere to before you commit to building a garden room.

In most cases, garden rooms are classed as outbuildings, which means you won't have to seek any kind of planning permission to build your space.

However, this applies to you only if you have permitted development rights at your home or the area you live in.

For example, you won't have permitted development rights if you live in a flat, tenement, maisonette or apartment building. If you're unsure about the rules for your home, please contact us or your local planning office for some advice.

Permitted development rights cover outbuildings or any build that could be considered "incidental" to the property. Essentially, they're anything that could be perceived as an addition to the main home.

As I'm sure you'll have gathered, this is where it can get complicated. What is considered "incidental" can vary from person to person, so it's always best to double-check with your local council if your building will comply with permitted development rules.

A good measure is to ask yourself whether your garden room could possibly cause any kind of disruption to the community on a regular and ongoing basis.

This is why you must be clear about what you intend to use your space for before beginning the building process. If you go ahead and build without planning permission, the council could ask you to apply for permission in retrospect. If your application is then denied, you'll have to take your garden building down.

Whether or not you need planning permission will also depend on your compliance with a few other rules.

The majority of these pertain to the height and the location of your new garden room. Should your room not meet these requirements, you may have to seek further permission from your local planning department.

These requirements are as follows:

• Your garden room cannot be in front of your house

• The total area of your room cannot exceed more than 50% of the total area around your house

• Your garden building must be single-storey and less than 3 metres high, or 4 metres with a dual pitched roof

• There is a maximum eaves height of 2.5 metres above ground level if you’re within 2 meters of your property boundary

• There is no balcony or veranda

• It isn't going to be used as self-contained living accommodation

If you're looking for a bit of extra studio space for artistic endeavours, music practice or a games room, and your building complies with the necessary dimension specifications, it's unlikely you'll need to seek planning permission.

However, there are always exceptions to the rule. Always seek professional advice from the council or call Hideaway garden rooms for more information.

If you plan to install your garden building with necessities that could be associated with the main house, such as a toilet and shower, this is no longer considered incidental and it's likely you'll have to apply for planning permission.

If your garden room is intended as a guest house or some kind of self-contained living accommodation, particularly if you're aiming to rent it out regularly, it's also likely you'll have to apply for planning permission.

You won't normally have to adhere to any building regulations, as long as your garden building:

• Does not include sleeping facilities

• Does not exceed 15 square metres

• Is not attached to your main home

If your garden building is between 15 and 30 square metres, you still won't have to comply with building regulations so long as there's no sleeping accommodation, it's more than 1 metre from your boundary and your building is made of non-combustible materials.

If your home is located on any World Heritage Site or an Area of Outstanding Natural Beauty, there are a few different building regulations you'll have to follow:

• The maximum size of the outbuilding (located more than 20 metres from your house) is 10 square metres

• If any part of your new building sits between the side of your house and the boundary of your property, you must seek planning permission

• For those living in listed buildings, you must automatically get planning permission for any outbuilding you plan to build
