Battersea (SW11) is one of South-West London's most desirable neighbourhoods, known for its iconic riverside views, lively high streets, and stunning Victorian and Edwardian homes. Whether you're near Battersea Park, close to Clapham Junction, along Lavender Hill, near Nine Elms, close to Northcote Road, or living around Queenstown Road, a loft conversion is one of the most practical ways to create new space without leaving SW11.
The main question homeowners ask is: Do I need planning permission for a loft conversion in Battersea?
This guide explains the rules, exceptions, Battersea loft conversion costs, and the ideal loft types for SW11 homes.
Do You Need Planning Permission for a Loft Conversion in Battersea?
Most Battersea homes fall under Permitted Development (PD) rights — but pockets of conservation areas and older stock mean rules vary.
When Loft Conversions Do Not Need Planning Permission
A loft conversion is typically allowed under PD if:
- Terraced homes add up to 40m³
- Detached / semi-detached homes add up to 50m³
- No dormer projects onto the front roof slope facing the road
- Dormer is set at least 20cm back from the eaves
- Exterior materials match the existing home
- Side-facing windows use obscure glazing
- No external balcony or raised platform is added
These rules often apply around Lavender Hill, Clapham Junction borders, Falcon Road, and parts of St John's Hill.
When Loft Conversions Do Require Planning Permission
You will need a planning application if:
- Your home is in a conservation area (parts of Battersea Park Road, Albert Bridge Road, and areas near Queenstown Road fall under this)
- You want a front dormer
- You plan a mansard loft
- Roof height needs to be increased
- Previous PD extensions were used
- Your home is a flat, maisonette, or converted property
Buildaway offers a free PD eligibility check for SW11 homeowners.
