Loft conversions have become a popular way to expand living space without the need to move home, especially in areas like Wandsworth where space is at a premium. However, before you start your project, it’s essential to understand the key difference between planning permission and permitted development rights, and when each applies to your loft conversion.
What is Permitted Development?
Permitted Development (PD) rights allow homeowners to extend or alter their properties without needing full planning permission, as long as the work adheres to specific criteria. For loft conversions in Wandsworth, your project may qualify for PD if:
The loft conversion adds less than 40 cubic metres of space for terraced houses or 50 cubic metres for detached and semi-detached homes.
No part of the extension exceeds the highest part of the existing roof.
The materials used match the existing house exterior.
There are no raised platforms, balconies, or verandas included in the design.
Side-facing windows are obscure-glazed and openable at 1.7 metres above floor level.
The roof extension is set back at least 20cm from the eaves.
These rules allow you to carry out a straightforward loft conversion without needing to apply for planning permission, making the process quicker and more cost-effective. However, there are some situations where PD won’t apply.
When Do You Need Planning Permission?
In certain circumstances, you will need to apply for planning permission for your loft conversion. This is often the case when:
You live in a conservation area: Parts of Wandsworth are designated conservation areas, where strict regulations protect the historical character of buildings. In these areas, loft conversions are usually subject to additional scrutiny, and PD rights may not apply. This is to ensure any alterations are in keeping with the overall look of the neighbourhood.
Your proposed design exceeds PD limitations: If your loft conversion involves significant changes, such as an extension larger than the permitted 40 or 50 cubic metres, or design features like balconies, raised platforms, or dormer windows facing the main road, you’ll need to apply for planning permission.
Alterations to the roofline: Changes to the roof, including the height or profile, require full planning permission. Any plans that involve extending beyond the original roof height will need approval.
Listed buildings: If your home is listed, you will need both planning permission and listed building consent for any type of loft conversion or structural work.
Which Route Should You Choose?
The decision between using permitted development rights and applying for planning permission depends on your home’s specific circumstances and the scope of your loft conversion. If your plans fall within the limitations of PD, this can save you time, money, and the complexity of the planning process. However, if you want to make significant changes, live in a conservation area, or have other restrictions, you will need to go through the planning permission route.
Steps to Take
Check if your property falls under permitted development: Before starting any work, it's important to confirm whether your home is eligible for PD rights. The Wandsworth Council website is a good resource, or you can consult a professional for advice.
Submit a Lawful Development Certificate: Even if you believe your loft conversion falls under PD, it’s a good idea to apply for a Lawful Development Certificate. This proves your project was completed lawfully without planning permission and can be crucial if you ever sell your home.
Consider consulting a professional: At Furzedown Builders, we recommend working with a qualified architect or building consultant to guide you through the process and ensure all regulations are followed, whether you’re working under permitted development or applying for full planning permission.
Prepare for the application process: If your loft conversion needs planning permission, factor in extra time for the council to review and approve your plans. This can take up to eight weeks, so plan your project timeline accordingly.
