About C3S Modular

We are a solution-led team of manufacturing and construction professionals with a mission: to help businesses and individuals realise better built-environment solutions than have traditionally been possible.

We do this by listening to the unique needs of every client; then through the application of 30 years’ worth of manufacturing, construction and project management experience, we design a solution that affords the full range of off-site manufacturing benefits – without sacrificing the design freedom usually confined to conventional methods of construction.

With a spectrum of solutions that include highly secure banking modules, military-grade guard houses, temporary ticket offices and domestic ‘home living modules’ (to name a few), our unique expertise ensures we are perfectly placed to develop simple off-site solutions to complex on-site problems.

Why C3S Modules?

As a specialist division of C3S Projects Limited – an established blast, ballistics and fire safety business – we have incredible experience of delivering built environment solutions that need specialist skills to overcome out-of-the-ordinary problems.

Twinned with our understanding of modular construction methods, C3S Modular offers a design and delivery package that has been fine-tuned to ensure each customer’s unique needs are met.

Whether for domestic, commercial or government use, we remove the complexity and risk associated traditional construction methods, delivering our ‘modules’ using a simple, tried and tested methodology.

Initial Consultation

Our expert team will take time to understand your needs, priorities and constraints, gathering as much information as possible to enable an initial concept and programme to be generated.

Site Survey

Our design team will evaluate the installation site and ensure any potential issues are identified and addressed prior to design and manufacture.

Planning Permission

Where required, our experienced team will guide you through the process of ensuring the necessary permissions are in place.


A full detailed design is generated ready for approval, taking account of all structural, functional, aesthetic and installation requirements.


We will carefully plan every element of production and installation, ensuring we keep you informed of exactly when we will need access to site.


With a carefully planned risk assessment and method statement, bespoke to the unique characteristics of each site, we ensure every installation is completed safely, efficiently and with minimal disruption.


If a module is no longer required at a particular site, our specialist removals team can ensure a module is quickly removed, with the site returned to its original condition. Modules can then be stored or refurbished ready for their next deployment.


C3S Modular aims to deliver solutions to the highest standards of quality and reliability possible, following best practise approaches at each stage of our operation.

To support our team and quality assure our processes, we have successfully achieved certification and accreditation with key industry bodies to deliver our products and services.
