Planning permission for a Garden Room – Complete guide
Are you planning to build a garden room in the UK? Find out if you need planning permission! This practical guide covers regulations and answers the most frequently asked questions. Building a garden room is not only a great way to increase the functionality of your garden but also an opportunity to create a unique space for work, relaxation, or pursuing hobbies. However, before starting your project, you need to check whether it requires planning permission. In this article, we provide a detailed explanation of the regulations in England to help you plan and execute your dream garden room in compliance with the law.
Do you need planning permission for a Garden Room?
Most garden rooms do not require formal planning permission as they fall under the category of permitted development. However, it is crucial to meet specific conditions to ensure that your project complies with current regulations.
When is planning permission not required?
The regulations for permitted development are designed to simplify the building process for smaller structures that have minimal impact on their surroundings. Here are the detailed guidelines that must be followed:
Location and Purpose
When planning a garden room, its location and intended purpose are key considerations to ensure compliance with regulations and maintain harmony with the surrounding environment. Proper placement and usage not only preserve aesthetic appeal but also adhere to legal requirements. Below, we outline the guidelines regarding the positioning and functionality of garden rooms.
Location in relation to the house
The garden room must not be built in front of the principal elevation of the house. This restriction aims to maintain the visual consistency of public spaces and prevent obstructions to the view of neighbors or passersby.
Purpose of the building
A garden room can be used as a recreational space, office, gym, or workshop, but it cannot serve as residential accommodation. This means that installing a kitchen, bathroom, or toilet requires additional permissions, as these features change the nature of the building to a more independent structure.
Maximum height of a Garden Room without planning permission
The height of the building is a critical factor in determining whether the project qualifies as permitted development. The regulations specify the allowable height based on the location of the garden room in relation to the boundary of the property:
- Within 2 Meters of the Boundary:
- The maximum height, including the roof, is 2.5 meters. This limitation is intended to minimize potential conflicts with neighbors, such as shading or obstructing their view.
- The maximum height, including the roof, is 2.5 meters. This limitation is intended to minimize potential conflicts with neighbors, such as shading or obstructing their view.
- More Than 2 Meters from the Boundary:
- Flat Roof: The maximum height is 3 meters.
- Dual-Pitched Roof: The maximum height is 4 meters, with a restriction that the side wall height must not exceed 2.5 meters.
Covered area
The regulations also address the area that a garden room can occupy within a garden to ensure a balance between structures and green space:
- Total Covered Area:
- Additional buildings, including the garden room, must not cover more than 50% of the land surrounding the “original house.” The term “original house” refers to the state of the property as it stood on or before July 1, 1948.
- Including Existing Structures:
- If other buildings are already present on the property, such as a garage, shed, or gazebo, their area must be included in this calculation.
- Purpose of the Restriction:
- These rules aim to preserve appropriate proportions between built structures and open garden spaces, promoting aesthetics, functionality, and environmental balance.
Example:
If you plan to construct a garden room measuring 4×4 meters (16 m²) with a flat roof and place it 3 meters from the boundary of your property, the project would meet the criteria for permitted development. However, adding a toilet, increasing the roof height above 3 meters, or placing the structure closer to the boundary would require additional planning permission.
When is planning permission required?
In certain cases, building a garden room may require formal planning permission. Below, you’ll find detailed information about situations where approval from local authorities is necessary.
The building exceeds permissible dimensions or height
- Location near the boundary of the property:
- If the building is located less than 2 meters from the boundary of the property and exceeds 2.5 meters in height, planning permission is required.
- These restrictions are designed to protect the privacy and comfort of neighbors and to prevent disputes related to shading or obstruction of views.
- Buildings with higher foofs:
- If you plan to construct a dual-pitched roof exceeding 4 meters in height or a flat roof exceeding 3 meters (when located more than 2 meters from the boundary), planning permission will be necessary.
The building is intended for residential use
- Change of use to residential function:
- Adding features such as a kitchen, toilet, or bathroom changes the classification of the building from an “auxiliary space” to a “residential dwelling,” which requires official approval for a change of use.
- Connection to utilities:
- Connecting the building to water, sewage, or gas networks requires agreements with local authorities and may involve additional technical and legal requirements.
The property is located in a protected area
- Areas of outstanding natural beauty (AONB):
- Construction in areas such as national parks, protected landscapes, or UNESCO World Heritage Sites must comply with additional restrictions.
- For instance, the maximum area of a building located more than 20 meters from the house is limited to 10 m² without planning permission.
- Conservation areas:
- In conservation areas, planning permission may be required even if the building meets other criteria, especially if it is visible from public spaces such as streets or parks.
The building is planned near listed properties
- Construction on listed properties:
- Any construction on the grounds of a listed property requires both planning permission and specific consent for modifications to a protected area.
- Additional regulations:
- In some cases, even small structures on the grounds of listed properties must comply with rules set by local heritage protection authorities.
When is planning permission required? – example
If you plan to build a garden room with a dual-pitched roof exceeding 4 meters in height, located 1 meter from the boundary of your property, you will need to apply for planning permission. Similarly, constructing a garden room in a conservation area or near a listed property typically requires additional approvals, regardless of the building’s size or function.
