A loft Conversion Often Falls Under Permitted Development, Which Means You Won't Need Planning Permission
This is subject to location-specific conditions
Wondering whether your loft conversion falls under permitted rights?
What Is Planning Permission For A Loft Conversion And Do You Really Need It?
Planning permission for a loft conversion is the approval given by the local authorities to make changes to an existing loft space. The need for such permission hinges on the scope of the work and how it interacts with planning regulations. In local residential areas, a loft conversion often falls under permitted development, which means you won’t need planning permission subject to specific conditions.
Loft Conversion Essentials: The Planning Permission Phase
For many homeowners planning their conversion, understanding whether you need planning permission or not can be a complex affair. The need for planning hinges on the scope of the work and how it interacts with planning regulations.
In local residential areas, a loft conversion often falls under permitted development, which means you won’t need planning permission subject to specific conditions.
Permitted Development Rights: What Are They And Do You Need Planning Permission?
Permitted development rights for loft conversions offer a streamlined path to extend your home without the need for planning permission.
These rights are detailed in the Town and Country Planning (General Permitted Development) (England) Order 2015. For instance, a dormer conversion is frequently permissible without permission, provided it doesn’t exceed the set back of at least 20cm from the original eaves and matches the height of the existing roof.
To be compliant with permitted development rights, your plans must not surpass 40 cubic metres of additional roof space for terraced houses or 50 cubic metres for detached and semi-detached houses.
Moreover, the conversion must not extend beyond the plane of the existing roof slope of the principal elevation or surpass the highest part of the roof.
When Planning Permission For A Loft Conversion Is Required?
You will require planning permission for a loft conversion if your proposed designs don’t meet the criteria for permitted development.
For example, a hip-to-gable conversion often falls within permitted development, but if your design exceeds the specific limits or modifies the roof structure substantially, a planning application will be necessary.
In conservation areas or designated lands such as an Area of Outstanding Natural Beauty or a World Heritage Site, loft conversions may need permission, even for changes typically covered by permitted development rights which will increase the cost of the project.
Always check with the planning department of your local council, if you are unsure of your specific circumstances.
Types of Loft Conversions And Planning Permission Considerations
Velux Loft Conversions: Generally do not require permission as they involve minimal structural changes.
Dormer Loft Conversions: These are a popular type of conversion in local residential areas with a high density of terraced houses due to the potential value increase of the property. These usually do not need permission if they adhere to the permitted development conditions.
Mansard Loft Conversions: A mansard conversion involves raising the roof pitch, almost always necessitating permission due to significant alterations to the roof’s profile.
Hip to Gable Loft Conversions: This type extends the sloping “hip” side of a roof to create a “gable” wall, often permissible under permitted development unless it significantly alters the existing roof slope.
The Planning Application Process: When Do You Need To Apply?
Submitting an application involves several steps and should be carried out before the scheduled work commences, including preparing detailed drawings and paying a fee. The local planning authority will review your application to ensure it aligns with local and national planning policies.
We recommend reaching out to your local building authorities to obtain the precise requirements and regulations for your loft conversion, regardless of the style you envision, ensuring you have all necessary planning in place.
Building Regulations And Their Purpose For Loft Conversions
Regardless of whether permission is required, your loft conversion must comply with building regulations to ensure structural stability, fire safety, and energy efficiency. This approval is a separate process that assesses the technical aspects of the work.
Building Regulation Approval For Loft Conversions
For approval, aspects like the structural strength of the new floor, the stability of the existing structure, safe escape from fire, and sound insulation must be considered. Dormer conversions, for example, must also adhere to these regulations, especially if they alter the roof structure.
Local Planning Authority And Loft Conversions
Consulting with the local authority or a planning consultant early on can provide clarity on whether you need permission or not. The authority can offer pre-application advice, helping you understand the process and required standards for the project.
Your Loft Extension: Planning And Building Regulations
When considering converting your loft, it’s crucial to be aware of both the permissions and regulations required. Even if you do not need permission for your conversion, building regulations are mandatory and ensure the safety and quality of the construction work.
