If you’re planning a loft conversion, you’ve likely heard the term permitted development. For many homeowners, this is an important factor that can make the process easier and more affordable. But what exactly is permitted development for loft conversions? In this guide, we’ll break down everything you need to know about loft conversion permitted development, the rules involved and how Alvaston Loft Conversions can help ensure your project is compliant.
What is Permitted Development?
Permitted development rights allow homeowners to make certain changes to their homes without needing to apply for full planning permission. Created to simplify small-scale home improvement, loft extension permitted development makes it easier to carry out work without the delays and costs associated with planning applications.
However, not all loft conversions fall under permitted development rights. Specific rules and building regulations must be followed to ensure your loft conversion is legal.
Criteria for a Loft Conversion Under Permitted Development
To be considered permitted development, your loft conversion must meet the following criteria:
Size Limits
- For terraced houses, the additional roof space created by the conversion must not exceed 40 cubic metres.
- For semi-detached or detached houses, the limit is 50 cubic metres.
Roof Height and Shape
- The loft extension must not extend beyond the plane of the existing roof slope that faces the main road, also known as the principal elevation.
- No part of the conversion can be higher than the existing roof.
Materials and Appearance
- The materials used in the attic conversion must match the existing appearance of your home to blend seamlessly with the original structure.
Prohibited Features
- As a part of a permitted development loft conversion, verandas, balconies and raised platforms are not allowed.
Rules About Windows
- Side-facing windows need to be obscure-glazed to ensure privacy.
- Any parts of the window that can be opened should be installed at least 1.7m above the room’s floor level.
Rules About Eaves
- With the exception of hip-to-gable loft conversions, any extension must be set back at least 20 cm from the original eaves.
Designated Land Restrictions
- Loft conversions are not allowed on designated land such as conservation areas, national parks and areas of outstanding beauty under permitted development rules.
How Do I Know if I Need Planning Permission for a Loft Conversion?
While most loft conversions avoid planning permission and can be completed under permitted development, some situations require full planning permission. If your loft extension exceeds the size limits, significantly alters the overall appearance of your home or you live on designated land, you will need to apply for a loft conversion planning application.
Additionally, if your property’s permitted development rights have been removed by the local council, planning permission will be necessary for any loft conversion project.
