Shazia was helpful from my first enquiry to the delivery of my container. She sorted any query and enabled me to buy exactly what I was looking for. The driver who delivered container was also a credit to his company. Nothing was too much trouble and everything done with a smile .

What is a container office?

At S Jones Containers, we convert standard 10ft, 20ft, and 40ft ISO containers into precision-built offices with insulated steel panel walls, welded personnel doors, double-glazed windows, full electrical fit-outs, lighting, heating, and optional data cabling or shelving. Each unit is fabricated to exacting standards in our dedicated UK facility and can be customised to meet specific operational, regulatory, or site-based requirements.
