Builders in London
Based in Cheltenham, we take on larger building projects across London β extensions, renovations, conversions and commercial fit-outs, managed properly from start to finish.
A Cheltenham firm that travels to London
Let us be upfront: Viskonti Ltd is based in Cheltenham, not London. We are not going to pretend otherwise. What we do is travel into the capital for the kind of substantial building projects that make the journey worthwhile for you and for us.
Plenty of London homeowners and businesses want a builder they can actually trust β a firm that turns up, keeps its word and finishes to a high standard. If that is worth bringing in an out-of-town specialist for, we would love to talk.
We are fully insured, we plan carefully and we manage the distance so it never becomes your problem. You get the same tidy, dependable team our Gloucestershire clients rely on.

The London projects we cover
We focus on larger, well-defined jobs where careful planning and skilled work really pay off.
Extensions
Rear, side-return and storey extensions on London’s terraced and semi-detached homes, engineered to make the most of tight urban plots.
Renovations
Full refurbishments of period terraces and older flats β rewiring, replumbing and finishing to a standard that lasts.
Conversions
Loft, basement and flat conversions that unlock extra rooms and value in properties where floor space is at a premium.
Commercial Units
Offices, shops and commercial spaces refitted and refurbished, worked around your trading hours to limit downtime.
Structural Work
Load-bearing alterations, steelwork and knock-throughs handled with the right engineering and building-regs backing.
Full Fit-Outs
Where it suits the job, we can bring our fit-out, painting and decorating teams too, so one firm delivers the whole project.

Out-of-town, without the hassle
Bringing in a firm from outside London only works if the logistics are handled well. So we handle them β you should never feel the miles.
We plan the work in solid blocks with a clear schedule agreed before we start, so the team is on site and productive rather than commuting back and forth. For longer projects our tradespeople stay locally, which we arrange and cover ourselves.
One point of contact runs the whole job, updates you regularly and keeps materials, deliveries and trades coordinated. The result is a build that moves at pace and stays on budget, whichever London borough it sits in.
Our process for London projects
Talk & assess
We discuss the project in detail and, for larger jobs, arrange a site visit to London so we quote accurately rather than on guesswork.
Plan & schedule
You get a clear quote and a firm timeline. We block the work efficiently and sort accommodation and logistics on our side.
Build & manage
A dedicated team delivers the work with one project lead keeping you informed, the site tidy and the programme on track.
Finish & sign-off
We complete, walk you through everything, clear any snags and make sure you are genuinely happy before we head home.
