Frequently Asked Questions

Everything you need to know about modular buildings, our process and what to expect.

A modular building is a structure manufactured in a controlled factory environment, then transported and assembled on-site. Unlike traditional construction, 90% of the work is completed in our factory before delivery.

Key differences include:

  • Speed: 4-12 weeks vs 6-18 months for traditional builds
  • Quality: Factory precision with consistent conditions
  • Waste: 90% less site waste than conventional construction
  • Disruption: Minimal on-site work reduces noise and disturbance

Our modular buildings meet the same Building Regulations as traditional construction, including Part L 2021 energy efficiency standards.

Typical timelines from order to handover:

  • Small units (under 30sqm): 4-6 weeks
  • Standard buildings (30-100sqm): 8-10 weeks
  • Large or complex projects: 10-12 weeks
  • Multi-storey buildings: 12-16 weeks

On-site installation typically takes just 1-3 days once the foundations are prepared. This compares to 6-18 months for equivalent traditional construction.

It depends on the size, location and intended use:

  • Permitted Development: Many garden rooms and small outbuildings under 15sqm fall under permitted development rights
  • Temporary structures: Buildings for less than 28 days may not require permission
  • Commercial and educational: Usually require full planning permission
  • Change of use: May require permission depending on the site

We can advise on planning requirements for your specific project and assist with applications where needed.

All KC Modular buildings come with comprehensive warranty coverage:

  • 15-year structural warranty on the frame and main structure
  • 24-month warranty on minor defects and finishes
  • Manufacturer warranties on components like windows, doors and heating systems

Our buildings are designed for a 50-75 year lifespan with proper maintenance. Premium lodges built to BS3632 standards are certified for permanent residential use.

Yes. All our modular buildings are designed and manufactured to meet current UK Building Regulations:

  • Part L 2021: Energy efficiency with U-values as low as 0.11 W/m2K
  • Part M: Accessibility and DDA compliance
  • Part B: Fire safety with REI60 rated options and FD30/FD60 doors
  • BB103: Acoustic standards for educational buildings

We hold ISO 9001, ISO 14001, ISO 1090 and are SSIP and Constructionline accredited.

Our standard payment structure is:

  • 40% deposit on order confirmation
  • 55% payment before delivery to site
  • 5% retention within 14 days of handover

We also offer asset finance options for businesses looking to spread the cost. This allows you to preserve capital while acquiring a quality modular building. Contact us for a finance quote tailored to your project.

Yes - this is one of the key advantages of modular construction:

  • Relocatable: Buildings can be dismantled and moved to a new site
  • Expandable: Additional modules can be added to increase space
  • Reconfigurable: Internal layouts can be modified as needs change
  • Stackable: Our ISO Frame system supports up to 3 storeys

This flexibility makes modular buildings ideal for growing businesses, temporary projects or sites where future changes are anticipated.

Before your modular building arrives, the site typically needs:

  • Foundations: Concrete pad, piles or ground screws depending on building size
  • Access: Clear route for delivery vehicle and crane
  • Services: Electrical, water and drainage connections to the boundary
  • Clearance: Overhead space for crane lifting

We provide detailed site preparation specifications and can recommend groundwork contractors if needed. Foundation work can often be completed while your building is being manufactured.
