Bespoke Modular Buildings Manufactured in the UK

Portable cabins, modular offices, classrooms, welfare units and eco-pods — designed, built and installed UK-wide.

If you need space fast, modular is a smart choice. First, we help you pick the right layout. Then, we build most of it in our factory. As a result, your site stays cleaner and quieter. Finally, we deliver and install with a clear handover.

  • Faster builds: up to 90% factory-completed, so on-site time is shorter.
  • Lower disruption: fewer deliveries and less mess, which helps busy sites.
  • Energy-focused options: insulated systems and modern glazing, so running costs can be lower.
  • Built to suit: we can plan for fire safety and access needs where required.

Warranty: 15-year structural warranty + 24-month minor defects cover. Also, we offer clear payment stages and support after handover.

Why choose KC Modular Buildings?

We build modular spaces for work, learning and site welfare. However, we keep the process simple. For example, we confirm your needs early, so there are fewer changes later. In addition, we plan delivery and install dates up front.

  • Factory build quality: controlled build steps for steady results.
  • Fast lead times: often 8–12 weeks, although it depends on size and spec.
  • UK-wide delivery: planned transport and install, so your site team can prepare.
  • Flexible use: offices, classrooms, welfare, healthcare and more.
  • Insulated build: typical U-values 0.25–0.38 W/m²K depending on the build.
  • Options for compliance: fire-rated and access-friendly layouts where needed.

If you want an independent overview of off-site building, you can read the UK Government guidance on Modern Methods of Construction (MMC) . This helps you compare modular to traditional builds.

Next, tell us your use case and postcode. Then we can suggest the best layout and a budget range.

  • Double or triple glazing options (project dependent)
  • UK-standard electrical options (BS7671 18th Edition routes)

Compliance options

  • Energy performance options aligned to Part L goals
  • Fire-rated options available (e.g., FD30/FD60 doors where required)
  • Access-friendly layouts (Part M options)
  • Fit-out options: toilets, showers, kitchens, data and HVAC

Guide pricing (from)

  • ISO office units: from £600/m²
  • Custom modular garden rooms: from £1,000/m²
  • Bespoke commercial builds: from £1,850/m²

Final cost depends on size, spec, delivery, groundworks and fit-out. Therefore, we confirm pricing after a short call.
