Your Westminster builder.
Architect-led. One contract.
Westminster — SW1 around the Abbey and Victoria — has one of the highest listed-building densities in London. Residential stock is concentrated in pockets of mansion blocks, listed Georgian terraces and mews properties. Nicholas Elias RIBA leads every submission here.
Four services. One team. One number.
Westminster projects: mansion-block top-floor conversions, listed-building mansards and refurbishments, mews property conversions, and museum-grade interior work.
Loft conversions
House extensions
Renovations
New builds
Political heart of London — listed buildings and conservation throughout.
Westminster's SW1 conservation team is among London's most protective of rooflines visible from public spaces. Our Belgravia, Pimlico and Knightsbridge experience covers the same exacting standard.

What homeowners ask before booking a Westminster builder.
Is a loft conversion achievable in SW1 Westminster?
Possible but rare and highly bespoke — the listing density is exceptional and conservation officers protect every roofline visible from public spaces. When achievable, mansards are the norm, requiring listed-building consent and a 6–9 month design phase. Budgets typically start at £250k.
What services does 2VP offer in Westminster?
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 Westminster?
Yes. Our studio is at 20 Dawes Road in Fulham, which puts Westminster 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 Westminster 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 Westminster?
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 Westminster projects?
Yes — our portfolio page shows project galleries with photography, architectural commentary and project budgets. Recent Westminster work includes: Lord North Street mansard (Listed-building mansard, 2024); Cowley Street refurb (Whole-house refurbishment, 2023); Smith Square restoration (Listed-building restoration, 2024).
