Your Belgravia builder.
Architect-led. One contract.
Belgravia — the Thomas Cubitt stucco grid between Knightsbridge and Pimlico — is one of London's most architecturally homogeneous neighbourhoods. Listed buildings are the majority; Westminster's conservation policy is detailed and exacting. Nicholas Elias RIBA leads every submission.
Four services. One team. One number.
Belgravia projects: listed-building mansards on Cubitt terraces, interior refurbishments at the very highest specification, basement dig-outs, mews conversions, and museum-grade bespoke joinery throughout.
Loft conversions
House extensions
Renovations
New builds
Cubitt’s stucco grid — listed mansards and museum-grade interiors.
Belgravia's planning submissions require a detailed understanding of Westminster's conservation policy and listed-building consent procedures. Our experience in Chelsea, Knightsbridge and the wider RBKC/Westminster corridor gives us the design track record to deliver at this level.

What homeowners ask before booking a Belgravia builder.
How much does a Belgravia loft typically cost?
£200k–£350k all-in for a high-spec mansard on a typical Cubitt terrace, including listed-building consent fees, conservation-officer-approved detailing and museum-grade joinery. Premium projects on Eaton Square or Belgrave Square frequently exceed £400k.
What services does 2VP offer in Belgravia?
Across SW1 we deliver loft conversions, house extensions (side-return, rear, wraparound, double-storey, basement), whole-house renovations and period restorations, and new builds where the site allows. Every project gets RIBA-led design by Nicholas Elias, JCT contracting, and a 10-year HomePro warranty.
Does 2VP work in Belgravia?
Yes. Our studio is at 20 Dawes Road in Fulham, which puts Belgravia SW1 inside our core west and south-west London territory — close enough that the project manager is on site rather than on the phone. Delivered projects with photographs are at https://2vp.uk/projects.
What's 2VP's response time for Belgravia enquiries?
Same-day site visits, written feasibility within three working days. You can also use the free 60-second cost calculator on this page for an instant tailored estimate — no callback required.
Does 2VP cover all of Westminster or just Belgravia?
All of Westminster. Our delivery teams cover the entire borough as part of our wider west and south-west London catchment. Our subcontractor network is local to SW1 and surrounding postcodes.
Can I see 2VP's recent Belgravia projects?
Yes — our portfolio page shows project galleries with photography, architectural commentary and project budgets. Recent Belgravia work includes: Chester Square restoration (Listed-building restoration, 2023); Wilton Crescent mansard (Conservation-grade mansard, 2024); Lyall Street refurb (Whole-house refurbishment, 2024).
