House Refurbishment in Lambeth | RCB Design & Build
Full house refurbishments are our second-largest workload across Lambeth — period-property buyers typically take possession then refurbish before moving in. RCB Design & Build delivers house refurbishment projects right across Lambeth (SE11) from our Dartford base — typically on site within 48 hours of enquiry, with a fixed written quotation in 5 working days. Our typical house refurbishment project in Lambeth costs between £72,000 and £300,000 in 2026, with most mansion blocks and Victorian terraces landing around £186,000. We are FMB, TrustMark, Checkatrade and TrustATrader accredited and operate as a Principal Contractor under CDM 2015.
Clapham and Herne Hill see strong demand for L-shaped lofts and full-width rear extensions. Working out of London Borough of Lambeth's area, we know the planners, the local building inspectors, and the named conservation officers — that personal relationship cuts weeks off the consenting timeline. Our typical Lambeth project is on mansion blocks within easy reach of Brixton or Brockwell Park, and we work with a small panel of trusted London-area subcontractors we have used for years.
What's included in our house refurbishment price
Strip-out, structural alterations, full first-fix M&E (rewire, replumb, central heating), insulation upgrade where accessible, plasterboard and skim throughout, joinery, decoration. Second-fix kitchen/bathroom and finishes are client-supplied within agreed allowances. Our written quotation covers labour, first-fix materials, project management, scaffolding, skips, Building Control fees and statutory inspections. Second-fix materials (kitchens, bathrooms, flooring, tiles, paint, sanitaryware) are supplied by the client as a deliberate cost-control measure — this typically saves homeowners £14,880–£27,900 in trade markup. We exclude planning fees, party-wall surveyor fees and structural engineer drawings, which we coordinate at cost.
Lambeth planning, party walls and Building Regs
Clapham and Herne Hill conservation areas restrict rear-extension footprint and rooflight placement. Always survey for asbestos (pre-2000 housing), check joist depths before opening floors, and test the electrical earthing system before any rewire price is committed. Note that Lambeth has multiple conservation areas — design must match prevailing materials, roof shape and fenestration. Party Wall Awards are typically needed for any excavation within 3 metres of a shared wall — we coordinate the surveyor and serve notices. Building Control is lodged at the start, with inspections at foundation, damp-course, pre-plaster and completion stages.
Timeline and process for Lambeth projects
Full refurbs run 14–22 weeks on site for a typical 100–140 m² mid-terrace. Mid-renovation site visits happen weekly and we send a written report every Friday. We hold a weekly call with the client throughout, send a written progress report with photos every Friday, and the lead PM is always reachable on WhatsApp. From SE11 postcodes we can have someone on site within 48 hours of a phone call.
Guarantees and after-care
Every project we deliver in Lambeth is backed by a 12-month workmanship guarantee. Where we install manufacturer-warranted systems (roofing membranes, windows, MVHR), the manufacturer warranty (typically 10–25 years) runs alongside. As an FMB member we can also arrange an FMB-backed 2-year insurance warranty on qualifying Lambeth schemes — worth considering for any project above £50,000.
