What Is A Garden Room?
A garden room is a fully insulated, double glazed, electrically wired building usually made from wood. Whilst a garden room can be attached to the house rather like a conservatory they are most often stand alone buildings situated in the back garden.
Garden rooms are built like timber frame houses and come with house quality doors and windows. There are endless possible uses for a garden room such as a home office, studio, games room, home gym or teenagers den.
Depending on location, a garden room often doesn’t need planning permission, they come in a wide variety of styles, are quick to install and more cost effective than a conventional brick built extension.
Garden rooms are also known as garden offices, studios, huts, garden buildings, log cabins or outbuildings but are essentially all the same thing.
Do I Need Planning Permission?
Garden Rooms are considered to be permitted development, not requiring an application for planning permission*, provided all the following conditions are met. At Lancaster garden rooms we will work with you to make sure these are all met;
- Garden Rooms must be single storey with a maximum eaves height of 2.5 metres and maximum overall height of 4 metres with a dual pitched roof, or 3 metres in any other case.
- If the Garden Room is within 2 metres of the property boundary the whole building needs to be less than 2.5 metres high.
- You can build up to 50% of the area of all your garden.
- The area of your garden is all your land except the part the house stands on, so the area includes the front garden, side gardens and back garden, less the area of any other buildings, fuel tanks etc.
- No buildings are to go in front of the front elevation of the house
- Conservation areas; you cannot build at the front or side, but you can place a garden room in the back garden
- Listed buildings; need full planning permission.
- Areas of Outstanding Natural Beauty; maximum size is 10sq metres and it has to be at least 20 metres away from the house.
- Any new building must not itself be separate, self-contained, living accommodation and must not have a microwave antenna. In this case, it would need planning permission.
- *Should your garden room need planning permission (does not meet the above criteria), we can provide a full planning service for you. From design through to submitting a planning application
