Planning Permission

Garden Room Planning Permission

Whether you need planning permission to build a garden room depends on various factors such as the size, use, location, and specific regulations in your area. Here are some general guidelines to help determine if you need planning permission for your garden room.

Do I Need Planning Permission?

Our garden rooms do not usually require planning permission as they fall within Permitted Development Rules under Class E. However if you do not meet the following conditions and do requires planning permission, InFrame are on hand to assist you.

Permitted Development

Mostly, garden rooms fall under “permitted development” rights, meaning you don’t need planning permission if you meet certain criteria. Here are typical conditions for a garden room to be considered permitted development. The majority of InFrame Garden Rooms do not require planning permission.

Height

The maximum height for a garden room

  •  4 meters for a dual-pitched roof
  • 3 meters for other types of roofs
  • 2.5 meters if the building is within 2 meters of a boundary.

Size and Area

The garden room should not cover more than 50% of the total area of the garden, excluding the area of the original house.

Use

The garden room must be for a purpose incidental to the enjoyment of the dwelling house, such as a home office, gym, or studio or annex. It should not be used as a separate living accommodation.

Location

The garden room should not be placed forward of the principal elevation of the original house.

Listed Buildings and Designated Areas

Additional restrictions apply if your property is a listed building or in a designated area (e.g., conservation areas, national parks). In such cases, planning permission is more likely to be required.

WHEN WILL I NEED PLANNING PERMISSION?

FLAT OR MAISONETTE –  Permitted development rights do not apply to flats or maisonettes, however it may be possible to install a garden room depending upon the conditions of your leashold agreement with the landlord. Some leasehold agreements may contain the terms “license to alter” or “license to alter with freeholders permission”. It is best to consult with your landlord and obtain permission.

AREA OF LAND – If you wish to build more than half the area of land around the “original house”
