Design & specification
We translate your brief into the right Containex configuration — layout, insulation, windows, electrics, sanitary and finishes.
Containex specialists
Modular buildings, handled from first sketch to final lift.
Martlets Modular Consultants supplies the complete Containex range and manages every stage for you — design, order, delivery, craning and construction. Backed by 25 years in modular.

Direct
Close Containex partnership
We assist at every step of the way.
Buying a modular building involves far more than picking a unit. We take on the detail so you get a working building, not a delivery problem.
Ordering & procurement
Direct working relationship with Containex means accurate quotes, correct specification first time and realistic lead times.
Delivery & logistics
Transport planned around your site — access surveys, vehicle selection, timed deliveries and unloading arranged.
Craning & installation
Where lifting is required we arrange the crane, lift plan and installation team so the units land safely and on schedule.
Construction & fit-out
Stacked and linked configurations, staircases, walkways, roofing and connection to services — coordinated end to end.
Aftercare
Ongoing advice on relocation, expansion, resale and maintenance of your modular buildings for as long as you own them.
The full Containex range
Whatever the application, there is a Containex solution — and we will tell you honestly which one fits.
Portable office cabins
20ft and 10ft office units — site cabins, offices, classrooms and common rooms, ready to work in from day one.
Sanitary & WC cabins
WC, shower and welfare cabins with fresh-water plumbing rather than chemicals.
Storage containers
Secure, weather-tight material and storage containers in a range of dimensions.
Office & sanitary boxes
Compact, immediately deployable boxes for short stays and tight sites.
Modular buildings
Multi-storey complexes — site offices, schools, welfare villages and accommodation.
Supplementary cabin types
Bespoke and special container types, colours and specifications to order.

Why we build with Containex
After 25 years in modular we could specify anything. We keep coming back to Containex because the units arrive right, stand up to years of use and hold their value.
Built to last
Hot-dip galvanised steel frames, high-grade insulation and quality fittings — cabins that stay solid through years of relocation.
European manufacturing
Consistent factory production with tight quality control, not variable third-party assembly.
Genuinely modular
Panel construction means units link, stack and reconfigure — the building can change as your needs change.
Depot network
Depots across Europe keep availability high and lead times realistic, even at short notice.
Full accessory range
Staircases, walkways, roofing, electrics, sanitary fit-out and interior options all from one manufacturer.
Strong resale value
Well-specified Containex units hold their value and are easy to sell or re-hire later.
