We work in partnership with Ministry of Defence estate managers, Tier 1 contractors and key industry partners to deliver modular buildings that meet operational requirements with minimal disruption and demonstrable compliance.

Modular construction methods

Our offsite construction methods enable fast turnaround, reduced on-site labour and consistent quality control. These characteristics make our solutions well suited to time-critical and operationally sensitive environments.

You will find our modular buildings deployed across military training areas, airfields, naval dockyards and research and development facilities, each configured to the precise needs of the site.

  1. Compliance and Performance

    We deliver buildings that meet Ministry of Defence specifications and Defence compliance standards. Our designs are developed and tested to ensure they satisfy the performance criteria set by the client for safety, durability and habitability.

    How our solutions comply

    Our modular solutions can be custom-designed to meet the published defence accommodation and estate requirements for:

    • Temporary troop accommodation

    • Command centres and briefing rooms

    • Medical, welfare and ablution facilities

    • Secure working environments for classified tasks

     

    This approach ensures full alignment with ministry accommodation policies while delivering the speed, flexibility and quality advantages of offsite modular construction.

  1. Rapid, Secure and Scalable Solutions

    Our product range is designed for operational use in secure bases, live construction sites and remote training locations. We have extensive experience working to the Defence Infrastructure Organisation standards and provide:

    • Modular accommodation blocks
    • Welfare and ablution facilities
    • Secure offices and command centres
    • Medical units and briefing rooms
    • Temporary decant buildings for estate refurbishment
    • Storage and logistics hubs
    • Workshops
    • Blast-resistant and enhanced security units on request

     

    Each unit is configurable for services, heating, ventilation and internal layout to match site logistics and operational tempo.

  1. Security and Personnel Clearance

    Security is integral to all defence projects. Our standard personnel security process includes baseline clearance for office personnel and operational site staff. Personnel directly involved in sensitive tasks hold higher personnel security clearance where required.

    We operate strict access controls, secure data handling procedures and site induction protocols to maintain the integrity of secure environments throughout delivery and handover.

    Cyber Security Compliance

    In a sector where data security and digital resilience are critical, Portakabin meets the Defence cyber security requirements with annual renewal of its Cyber Essentials Plus certification. This ensures our systems and processes adhere to the highest standards for handling sensitive information, providing peace of mind for Ministry of Defence estate managers and contractors operating in secure environments.

  1. Quality, Robustness and User Experience

    Our buildings are engineered to provide consistent acoustic performance, efficient lighting and a high level of occupant comfort. We design for durability, low maintenance and predictable whole-life performance.

    Optional enhancements include ballistic protection and acoustic upgrades where required by the mission profile.

    Project Delivery and Contract Readiness

    We offer framework-ready delivery for public sector procurement, with units available for hire or for permanent installation. Our service includes full project management, coordination with site stakeholders and turnkey handover to client acceptance criteria.

    Our delivery model emphasises lean programmes and minimising on-site disruption while maintaining a documented quality and safety regime aligned to international management standards.
