About Clapham

Popular Services in Clapham
Wraparound kitchen extensions are the flagship project in Clapham, combining side return and rear extensions to create the large open-plan kitchen-diners that Clapham families demand. Loft conversions are the second most popular service, particularly L-shaped dormers on Victorian terraces that maximise headroom. We also handle a steady stream of full property renovations for buyers who purchase unrenovated period homes in Clapham and commission a complete refurbishment.
Planning & Building Control in Clapham
Clapham straddles two councils — Lambeth (most of SW4) and Wandsworth (areas near Clapham Junction in SW11). Lambeth is generally supportive of rear extensions under permitted development but has specific design requirements in the Clapham Conservation Area, including restrictions on roof materials and glazing styles. The Abbeville Road and Clapham Old Town conservation areas are particularly sensitive. We always confirm the planning authority for each property and check conservation area boundaries before quoting.
Clapham Property Insights
The Georgian properties around Clapham Common are typically Grade II listed or within conservation areas, requiring Listed Building Consent for any alterations. Victorian terraces in Clapham tend to have generous ceiling heights (2.8-3.0 metres) and original features like cornicing, fireplaces, and shutters that add value when preserved during renovation. The London Clay beneath Clapham means tree roots can cause subsidence — properties near mature trees may need underpinning or deeper foundations.
Common Projects in Clapham
Wraparound kitchen extension on a Victorian terrace
The signature Clapham project. Combines a side return infill with a 4-5 metre rear extension to create a substantial open-plan kitchen-diner of 30-40 square metres. The wraparound suits the wider Victorian terraces around Abbeville Road and the Wandsworth Common side. Cost is £75,000-£120,000 including structural steelwork, foundations on London Clay (typically 1.2-1.5 metres, deeper near mature trees), glazing (Crittall-style or bifolds), electrics, plumbing, and finishes. Build time 14-18 weeks. Party wall agreements are needed with both neighbours and add 4-8 weeks to the lead time before work starts.
L-shaped dormer loft conversion
Clapham's Victorian terraces have steep pitched roofs with good standing height for L-shaped dormer conversions, which create more usable floor area than a single rear dormer by combining a rear dormer with a side dormer over the back addition. Cost is £55,000-£85,000 including structure, staircase, en-suite plumbing, electrics, plastering, and decoration. Build time 10-14 weeks. The Clapham Conservation Area imposes restrictions on visible roof alterations — rear dormers are generally accepted, front-facing dormers refused. We design to Lambeth's guidelines from the outset.
Full property renovation on a Georgian or Victorian terrace
Clapham attracts buyers commissioning full refurbishments on unrenovated period houses. Scope typically includes rewiring to BS 7671, replumbing, knocking through the ground floor, new kitchen and bathrooms, plastering, and complete decoration. Original cornicing, ceiling roses, fireplaces, and shutters are preserved and restored. Cost is £120,000-£280,000 depending on size and specification. Build time 18-24 weeks with one team. For Georgian properties (typically Grade II listed), Listed Building Consent is required before any work and we apply for it as part of the project.
Period bathroom renovation with original feature preservation
Many Clapham clients renovate bathrooms while preserving original features — cornicing, ceiling roses, sash windows, original timber doors. The work involves stripping back to brick where needed, rerouting plumbing to suit modern layouts (walk-in showers, freestanding baths, twin basins), and finishing with premium sanitaryware and large-format tiles. Cast-iron soil stack replacement is common while the wall is open. Cost is £9,000-£20,000 for a full bathroom renovation. Build time 3-6 weeks. Underfloor heating is fitted as standard on most Clapham bathrooms.

Frequently Asked Questions
- Which council do I apply to in Clapham?
- Most Clapham properties fall under Lambeth Council (most of SW4), but areas near Clapham Junction in SW11 are under Wandsworth. The boundary runs roughly along Cedars Road and the railway line. We check the property's planning portal entry before any application to confirm which authority applies. Lambeth has specific design requirements in the Clapham Conservation Area, Abbeville Road conservation area, and Clapham Old Town conservation area. Wandsworth's process is generally faster for standard rear extensions. We handle the application as part of the project.
- Do I need Listed Building Consent on a Georgian property in Clapham?
- Yes, on virtually any change to a Grade II listed property. The Georgian terraces around Clapham Common are typically listed and require Listed Building Consent for alterations, including internal layout changes, removal or alteration of original features, replacement of original windows, and any external changes. Lambeth's conservation officer reviews each application individually. Application takes 8-12 weeks and runs in parallel with any planning application needed for new work. We've handled multiple Listed Building Consent applications in Clapham and know what Lambeth's officers expect.
- Why might my Clapham property need deeper foundations?
- Tree roots and London Clay. Mature trees on or near a Clapham property (particularly the plane trees around the Common and on the larger streets) extract moisture from the clay subsoil, which causes the clay to shrink and triggers subsidence. Standard foundations of 1.0 metres aren't enough on properties within 1-1.5 times tree height. The structural engineer specifies foundation depth (typically 1.5-2.0 metres or piled foundations) based on a trial hole and tree survey. Adds £4,000-£10,000 to extension cost compared with a tree-free site.
- How does parking and access work for a Clapham renovation?
- Most Clapham streets are controlled parking zones, and waste skips, scaffolding, or contractor vehicles need permits from the relevant council (Lambeth or Wandsworth). We arrange these as part of the project — typical cost £40-£80 per week per permit. For larger projects with concrete pumps, crane lifts, or multiple skips, we coordinate the schedule with the council to minimise disruption. Some Clapham streets have access restrictions for larger vehicles, and we sometimes use smaller vans or hand-carry materials over short distances. All of this is factored into the schedule and quote.
