Do You Need Planning Permission For A Loft Conversion In West London?
It’s a common question: Do I need planning permission for a loft conversion in West London?
The answer depends on the size and type of your project. Many loft conversions fall under permitted development in West London, meaning formal permission isn’t always necessary. However, if you plan to make substantial changes to your roof structure, live in a conservation area, or own a listed building, you will likely need permission from your local authority.
At Touchstone Lofts, we conduct a detailed assessment to determine whether a loft conversion planning application in West London is required. Rest assured, we’ll handle the process from beginning to end.
Permitted Development Rights In West London
If your home benefits from permitted development rights, you may not need to submit a planning application. This is often the case if:
-
The extension doesn’t exceed 40m³ for a terraced house or 50m³ for a detached/semi-detached home.
-
The conversion does not extend beyond the existing roof slope.
-
No balconies, verandas, or raised platforms are added.
-
Building materials are similar to those used in your existing home.
Homes in conservation areas or flats typically don’t have permitted development rights. To avoid legal and financial complications, we recommend speaking to our team before starting your project.

Planning Rules For Loft Conversions You Need To Know
Several planning rules for loft conversions must be followed to ensure your project meets legal requirements. These include:

-
Side-facing windows must be obscure-glazed to maintain privacy.
-
Windows must be set 1.7 metres above the floor inside the room.

Roof extensions should not overhang the outer wall of the original house.
