On-Site Office Cabins, Practical, Secure Workspaces for Every Site

Our site office cabins are designed to give you a reliable, comfortable, and secure place to manage your project – right where the work is happening. Whether you’re overseeing operations, coordinating trades, handling paperwork, or hosting meetings, these portable office units give your team a dedicated space to stay organised and productive.

Built for construction sites, infrastructure projects, and temporary setups, each unit is fully insulated and fitted with plug-and-play electrics, desks, seating, and filing cabinets. This creates a comfortable working environment all year round, so you can keep your project moving regardless of the unpredictable British weather.

Ideal for sites with limited space, our container-based offices can be double stacked to maximise your footprint without compromising functionality. They’re trusted by site managers, contractors, and project teams across the South who need quick, secure, and flexible office space delivered fast.

We have been using SOS for approx 10 years. Possibly the best company we have the pleasure of dealing with. In every aspect they excel. Don’t know how they do it, but I’m glad they do 👏👏👏👏

Great experience with Storage on Site today. Mouse helped us arrange the welfare units for our project - he was helpful, polite and made the whole process easy. It was a pleasure working with him. I'd happily recommend Storage on Site. Thanks!

Received our new 20ft container in RAL6007 this morning and it looks fantastic and Storage on Site driver Harry Wood made an excellent job with positioning the container in our clients preferred position. Great work Harry and our client was extremely happy, well done.

S.O.S containers are our incumbent suppliers here at the Chewton Glen Hotel & Spa. Nothing is too much trouble! Dwayne their delivery driver is a legend! Incredibly skilled lifter, managed to tuck a container under a gable and get it much closer than I thought possible to the wall, not a scratch on anything. Handy reversing with a trailer too. Would I recommend Storage on Site, definitely. Would I play Jenga against Dwayne.... No! Andy Barnes Facilities Manager Chewton Glen Hotel & Spa

Excellent service from start to finish. The containers we had delivered were absolutely immaculate — perfectly clean, in excellent condition and exactly what we needed. I was particularly impressed with how well presented they were on arrival. Kim and her team have been fantastic throughout the whole process. Communication was excellent, everything was well organised, and the delivery went very smoothly. Nothing was too much trouble, and the level of customer service has been first class. It has been a pleasure dealing with such a professional, friendly and helpful company. I would have no hesitation in using them again and would highly recommend them to anyone looking for containers and a reliable, high-quality service. Thank you again to Kim and the whole team!
