Introduction
SW11 is one of south London’s most dynamic and rapidly transforming postcode areas, covering Battersea, Clapham Junction and the surrounding streets in the London Borough of Wandsworth. The postcode has been at the centre of one of London’s most dramatic regeneration stories — centred on the iconic Battersea Power Station, now transformed into a mixed-use development with hundreds of new homes, shops, restaurants and its own tube station.
The housing stock of SW11 is diverse: Victorian terraces of real quality in the streets between Battersea Park Road and Northcote Road; the imposing Victorian mansion blocks on the streets near Clapham Junction; new-build apartment buildings in the Battersea Power Station development; and the characterful mix of housing types in the Battersea Conservation Area north of the park. This diversity creates a range of architectural project types that Crown Architecture is well-positioned to deliver.
The streets around Northcote Road — one of south London’s most popular family high streets — contain a particular concentration of Victorian terraced houses where the demand for extensions and refurbishments is very high. Families are investing in rear extensions, loft conversions and comprehensive refurbishments that transform these well-proportioned Victorian homes into excellent contemporary family houses.
Wandsworth Council’s planning team handles all applications in SW11. The Battersea Conservation Area, Battersea Park Conservation Area and other designations in the postcode create a planning framework that requires careful navigation. Crown Architecture brings the local knowledge and design expertise to deliver outstanding results for SW11 projects of every type.
Our Services
Rear Extensions: Victorian terraces in SW11 have strong rear extension potential. We design single-storey rear extensions creating open-plan kitchen-dining-family rooms, often with flat glazed roofs and bifold doors to south or west-facing gardens. Combined with side-return infill, these projects can deliver exceptional results on well-proportioned Victorian terraces.
Loft Conversions: Rear dormer loft conversions are a popular and cost-effective way to add a top-floor bedroom suite to SW11 Victorian terraces. We design loft conversions to comply with Wandsworth’s design standards and to maximise the space and light achieved on the top floor.
Refurbishments and Reconfigurations: For SW11 properties that have not been updated for many years, Crown Architecture provides comprehensive refurbishment designs that improve the interior planning, restore original features and upgrade all services and finishes.
New-Build Apartment Interior Design: For buyers of new-build apartments in the Battersea Power Station development and other new-build schemes in SW11, Crown Architecture provides interior design and fit-out services — customising developer-standard apartments to a high personal specification.
Planning Advice: We provide pre-application feasibility advice for all SW11 projects, confirming the planning route and likely requirements.
Planning Authority & Local Planning Context
All planning applications in SW11 are submitted to London Borough of Wandsworth. Wandsworth operates an online planning portal and applies its policies through the Wandsworth Local Plan.
Battersea Conservation Area: The Battersea Conservation Area covers significant parts of the northern section of SW11, protecting the Victorian and Edwardian residential streets near Battersea Park. Within this designation, most extensions and external alterations require full planning applications.
Battersea Park Conservation Area: The Battersea Park Conservation Area covers the park and its immediate surroundings. Applications affecting properties within or adjacent to this area are subject to additional scrutiny.
Battersea Power Station Development Area: The Battersea Power Station Opportunity Area has its own planning framework, and applications for works to properties within the development area are subject to specific policies.
Typical Planning Issues in SW11: Securing permission for rear extensions in conservation areas; managing daylight and overlooking on Victorian terraces; designing loft conversions that satisfy Wandsworth’s design standards; and managing the planning requirements that apply in the Battersea Power Station development area.
Project Examples
Northcote Road Victorian Terrace, SW11: A three-storey Victorian terrace on Northcote Road was the subject of a rear extension and loft conversion by Crown Architecture. The single-storey rear extension of 26 sq m, with a full-width glazed rear wall and sliding doors to the garden, created a new open-plan kitchen-dining room. A rear dormer loft conversion added a principal bedroom suite. The project was outside the conservation area, and both elements were delivered under permitted development. A Lawful Development Certificate was obtained, and the project was completed within 5 months.
Battersea Park Road Victorian Terrace, SW11: A Victorian terraced house on Battersea Park Road — within the Battersea Conservation Area — was extended and refurbished by Crown Architecture. The rear extension of 20 sq m required a full planning application to Wandsworth. Pre-application engagement with the planning officer established the acceptable materials and design approach. London stock brick and a flat roof with roof lights were approved. The full refurbishment included new kitchen and bathrooms, restored sash windows and cornices, and a full services upgrade.

Wandsworth requires materials sympathetic to the Victorian character of the conservation area. Stock brick, slate or zinc roof coverings and appropriate window specifications are typical. Crown Architecture advises on appropriate material choices.
Local Character
SW11 has a diverse and evolving urban character. Northcote Road is Battersea’s famous family-friendly high street — with a street market, restaurants, delis and boutiques it has an exceptional quality of life for young families. Lavender Hill runs east-west through the heart of the postcode as the main commercial artery. St John’s Hill connects the Clapham Junction railway interchange — one of Europe’s busiest railway stations — to the wider neighbourhood. Battersea Park Road provides access to the magnificent Battersea Park.
Battersea Power Station station (Northern line Battersea extension) now connects SW11 to the wider tube network for the first time, a transformative addition to the postcode’s transport offer. Clapham Junction remains the primary railway interchange for the postcode.
Battersea Park — a 200-acre park on the south bank of the Thames with an athletics track, ornamental lake, Peace Pagoda and children’s zoo — is SW11’s defining open space.
