About Battersea
Battersea has undergone a dramatic transformation in recent years, but behind the riverside developments lies a core of beautiful Victorian terraces and mansion flats that reward thoughtful renovation. Streets around Battersea Park, Northcote Road, and Lavender Hill are lined with period properties where homeowners invest seriously in extending and upgrading their homes.

Popular Services in Battersea
Kitchen extensions dominate in Battersea — the classic Victorian terrace layout with a dark rear kitchen is transformed by a single-storey rear extension with bifold doors opening onto the garden. Side return extensions are equally popular, particularly on the terraces between Clapham Junction and Wandsworth Common where the side passage is wide enough for a meaningful gain. Bathroom renovations in Battersea tend to be at the premium end, with clients specifying high-end fixtures, underfloor heating, and walk-in showers.
Planning & Building Control in Battersea
Battersea falls under Wandsworth Council, which has a reputation as one of the more permissive London boroughs for residential extensions. Most single-storey rear extensions proceed under permitted development without issue. The Wandsworth Common and St Johns Hill conservation areas have additional design requirements. Wandsworth Council operates a pre-application advice service that we use to confirm feasibility before committing to designs on complex projects.
Battersea Property Insights
Victorian terraces in Battersea typically have London stock brick walls, timber floors, and slate roofs. Many properties in SW11 have basements that can be converted, though the high water table near the river means tanking and waterproofing are critical. The clay subsoil across Battersea requires foundations of 1.2-1.5 metres for extensions, and properties near the Thames may need additional ground investigation.
Common Projects in Battersea
Single-storey rear kitchen extension on a Victorian terrace
The flagship Battersea project. The terraces around Northcote Road, Lavender Hill, and Battersea Park Road have classic dark galley kitchens at the rear that get transformed by a 4-5 metre rear extension with bifold or sliding doors and a roof lantern. Cost is from £55,000 including structural steelwork, foundations on Battersea clay (typically 1.2-1.5 metres), glazing, electrics, plumbing, and finishes. Build time 12-14 weeks. Wandsworth Council's permitted development process is efficient for the standard 3-metre rear extension, and most projects don't need a full planning application.
Side return extension on a terrace
The terraces between Clapham Junction and Wandsworth Common have side passages of 1.0-1.5 metres that suit infilling with a glazed roof and steel-framed structure. Combined with knocking through the existing kitchen wall, the result is a wide open-plan kitchen-diner without giving up garden space. Cost is from £35,000 including structural steelwork, foundations, glazing, electrics, plumbing, and finishes. Build time 8-12 weeks. Party wall agreements with the neighbouring property are needed because the side return shares a boundary wall, and we serve notice early to avoid scheduling delays.
Basement tanking and conversion
Many Battersea Victorian terraces have unused or underused basements that can be tanked and converted into utility rooms, wine stores, home offices, or guest accommodation. The high water table near the Thames creates groundwater pressure that pushes water through brickwork, so a waterproof membrane system (Newton or Triton) is essential. Cost is from £15,000 for tanking; converting to habitable use adds £20,000-£50,000 depending on specification. Build time 10-16 weeks. We do a ground investigation before quoting on properties within 100 metres of the river.
Premium bathroom renovation
Battersea bathrooms are typically at the premium end — Duravit or Lefroy Brooks sanitaryware, Crosswater or Hansgrohe brassware, large-format porcelain or natural stone tiles, frameless walk-in showers, and underfloor heating. The Victorian terraces here often still run on gravity-fed hot water with a cold tank in the loft, and clients usually take the opportunity to switch to an unvented cylinder or combi boiler during the bathroom renovation. Cost is from £8,000 for a full bathroom renovation. Build time 3-5 weeks. Cast-iron soil stack replacement is a common add-on while the wall is open.

“So happy with the work done by Les and Richard!! We bought a house that needed new paint, cracks filled, a new bathroom fan and some mold removal and they did it all. The quality of the work is phenomenal; it looks like a brand new house. We’ll definitely be hiring them for our future projects!”

Frequently Asked Questions
- How does the Thames affect renovation projects in Battersea?
- Properties within 100 metres of the river typically have higher groundwater levels, which matters for any below-ground work. Basement conversions need full waterproof tanking systems (Newton or Triton membranes) rather than simple damp proofing. Extensions may need a ground investigation to determine the water table depth before foundations are designed. The Environment Agency flood risk maps cover most riverside SW11 properties, and we check the flood zone designation at the survey. Properties further from the river (Battersea Rise, Northcote area) have standard clay subsoil and don't have the same groundwater issues.
- Why do extensions cost more in Battersea than in surrounding boroughs?
- Two reasons. First, the Battersea clay subsoil requires deeper foundations (1.2-1.5 metres) than sandy areas, and properties near mature trees may need 1.8-2.0 metre piled foundations. Second, the local market expects premium finishes — Crittall-style glazing, roof lanterns, premium kitchens, underfloor heating — which add cost over standard specifications. The Wandsworth Council planning fees are standard, and Building Control fees are typical for London. The cost premium over outer boroughs is typically 15-25% for an equivalent project, mostly in foundations and finishes.
- Can I extend a Battersea property in a conservation area?
- Yes, but with constraints. The Wandsworth Common, St Johns Hill, and other Battersea conservation areas require visible alterations to match the existing character. Rear extensions are usually fine because they're not visible from the street. Front-facing dormers on loft conversions are generally refused; rear dormers are accepted. Wandsworth Council's pre-application advice service is useful for confirming feasibility before committing to designs. Listed buildings (Grade II is most common) need Listed Building Consent before any work, and we apply for that as part of the project.
- How long does a Battersea kitchen extension take?
- Twelve to fourteen weeks for a standard 4-5 metre rear extension on a Victorian terrace, weather permitting. Schedule is roughly: weeks 1-2 groundwork and foundations, weeks 3-4 structural walls and steelwork, weeks 5-6 roofing and weatherproofing, week 7 first-fix electrics and plumbing, weeks 8-9 plastering and second fix, weeks 10-11 kitchen fitting, weeks 12-14 painting and snagging. We provide a detailed programme of works before starting and photo updates throughout the build throughout. Side return extensions and wraparounds add 2-4 weeks to the standard rear-extension timeline.
