Modular Buildings UK
Adacon builds modular buildings around a single system — the P600. One module is a complete, insulated, fitted room. Join them side by side and stack them, and the same system becomes an office building, a welfare block, a clubhouse or a classroom.

One module, one specification
Every P600 arrives with a galvanised steel chassis, full wall, floor and roof insulation, plastered and painted internal walls, flooring, LED lighting, power sockets and double-glazed uPVC windows and doors. Most of what other suppliers treat as an upgrade is included as standard, which is why the price is quoted per module rather than as a long options list.
Joined side by side
Modules link to make one continuous space, or stay separated by internal partitions where you need distinct rooms. A run of two gives roughly 26 m², four gives roughly 52 m². Additional modules can be added to an existing building later without disturbing what is already there.
Stacked over two storeys
Modules stack, with internal, external or covered external stairs. Two-storey arrangements are reviewed for foundations and structure per project, and roof terraces can be formed over exposed ground-floor modules.
Fitted out for the job
Kitchens, WCs, showers, partitions, glazing configurations, data and heating provision are all specified before the module is built, so the unit lands close to complete. The remaining site work is usually the base, the connections and commissioning.
Finished to suit the site
Cladding style and colour are chosen wall by wall — smooth, vertical, horizontal or timber-effect — so a gatehouse can match a corporate frontage and a garden room can suit the house behind it.
Portable, prefabricated, modular
You'll see this category described as portable buildings, prefabricated buildings, portable cabins and container conversions. Our units are prefabricated off site and are relocatable, but the finish level sits closer to a purpose-built room than to a traditional site cabin — which is why we describe them as modular buildings.

Common questions
What is a modular building?
A building manufactured off site in complete volumetric modules, then delivered and connected on site. Because the build happens in a factory, the programme is shorter and more predictable than traditional construction.
How much does a modular building cost?
Our P600 is priced per module, with the majority of a standard fit-out included. The configurator gives an estimate as you design; a fixed quotation follows before order.
How long does a modular building last?
The steel chassis and construction are designed for long-term use, and the units are relocatable. Life depends on the site, the use and maintenance.
Do modular buildings need planning permission?
It depends entirely on the use and the site. Domestic garden buildings often fall under permitted development; commercial, education and accommodation uses usually need permission. Check with your local planning authority.
Can modular buildings have toilets and kitchens?
Yes — WCs, showers and kitchens can all be built in, subject to water supply and drainage on site.
How are they delivered?
Modules are craned or forklifted onto a prepared level base. We check access and craneage before booking delivery, across UK mainland and Northern Ireland.
