Modified Shipping Containers

Modified shipping containers start as standard steel boxes and leave our yard set up for a specific job: a site office, a workshop, a pop-up shop or a secure store with shelving and lights already fitted. Buying a container that is modified before delivery saves you hiring separate trades on site and gets the unit working the day it arrives.

Choosing the base for modified shipping containers

The box you start with matters. For offices and living spaces, a 40ft high cube container gives extra headroom once insulation and a ceiling go in. For a compact workshop, one of our 20ft shipping containers is often enough. A one trip unit is the best base for anything customer-facing, as explained in one trip vs used shipping containers. Our high cube vs standard guide explains why height matters for conversions.

Ideas for modified shipping containers

  • Site offices and canteens for building projects.
  • Workshops with benches, power and lighting.
  • Retail kiosks, coffee bars and pop-up stores.
  • Pump rooms, generator housings and equipment shelters.
  • Studios, garden rooms and storage with shelving.

Container conversions have become a design field of their own; the shipping container architecture article shows how far the idea can go.

Planning tips

Check local building and planning rules before you order, especially for occupied buildings. Think about where power and water will connect, and which way doors and windows should face once the box is placed. Our delivery guide helps you prepare the ground.
