Modified units

Custom container builds: offices, retail units and technical enclosures

A modified container gives you a permitted-friendly, relocatable building with the structural envelope already paid for. We start from one-trip stock so the shell is clean and square, then cut, reinforce, insulate and fit out to your drawing. Typical programmes run four to six weeks from approved shop drawings to delivery.

Fabrication capability

  • Drawing-led fabrication

    Every conversion starts from a stamped shop drawing showing cut lines, header reinforcement and penetration locations, so the ISO frame keeps its racking strength after we open the shell.

  • In-house steel and finish work

    Doors, windows, partitions, HVAC penetrations and mezzanines are cut and welded at our Johannesburg fabrication shop, then finished in two-coat industrial enamel or brand-matched wrap.

  • Inspection-ready documentation

    Builds ship with an as-built drawing set, electrical load schedule and materials list — the paperwork most permit offices ask for before a temporary occupancy sign-off.

  • Delivered as one lift

    Corner castings stay intact, so a finished unit is still craneable and tilt-bed deliverable. No on-site assembly crew and no foundation pour required.

Available modified units

26 turnkey builds currently in the programme. Each is configurable further on its detail page.
