On a tight London plot, the first question isn't cost — it's whether the extension can be built at all. Here's why the no-crane method changes what's possible on terraced and side-return sites across the capital.
The point most London quotes miss: On a London terrace, the first question isn't "what will it cost?" — it's "can this even be built here?" Restricted access, party walls and mature gardens defeat crane-lifted and heavy-plant builds before price is even discussed. Vita Modular's panels are hand-assembled with no crane and no heavy plant, so tight side-returns and rear-only sites are buildable — and access doesn't add to the price.
Elsewhere in the country, an extension conversation starts with size and budget. In London it starts with a harder question: is there any way to get the materials and machinery to the back of the house at all?
The typical London property — a Victorian or Edwardian terrace, a semi with a narrow side passage, a home with a mature garden and no rear vehicle access — is exactly the kind of site that defeats conventional and crane-lifted modular builds. If a build method needs a crane to lift a module over the roof, or heavy plant in the garden, a terraced street with no side access simply rules it out. That's why, in London more than anywhere, whether you can build shapes the project long before what it costs does.
Vita Modular's system is panelised, not volumetric. The structural frame and insulated panels are precision-made off-site, delivered flat on a standard lorry, and hand-assembled on site by a small in-house team — with no crane and no heavy plant. On a constrained London plot, that's the difference between a viable project and a non-starter.
And because there's no crane hire, no road closures and no plant to bring in, site access doesn't affect the price — a tight terraced plot is built at the same rate as an open one, with no access surcharge.
Almost every London extension engages the Party Wall etc. Act 1996, because you're building right up to a boundary shared with close neighbours. It's not a reason not to build — it's a normal, manageable part of the process. Vita provides party-wall and planning support across every London borough, and either builds to your pre-approved drawings or produces and manages the planning application for you, which is often more cost-effective than instructing an architect separately.
Much of residential London sits in a conservation area or on a period terrace with strict material requirements. A modular system can meet them: Vita matches effectively any external finish a conservation condition requires — brick slip, timber, render — with the frame and panels behind a compliant façade, and complex hand-laid brickwork detailing is well within scope.
Once you know a site can be built, the cost question becomes answerable. Vita Modular extensions in London start from £34,000 inc. VAT, at a fixed all-inclusive shell rate, with kitchens, bathrooms and groundworks quoted separately.
