20-Foot Office & Storage Combo Containers

Storage and temporary office needs are never fixed. Sometimes you start out thinking that you just need a temporary space to work in, but soon realize, “Wow, I wish I also had a place to store all of this unused equipment that’s surrounding me.” 


For moments like these, standard portable storage units just won’t cut it. 


If you’re looking for a multi-purpose portable unit where you can work and store business supplies and equipment, then our 20ft office and storage combo containers are a perfect fit. These units provide the same portable storage capacity as our traditional 20ft storage units, but they have added office space that allows you to work right inside.

What Is a 20ft Office and Storage Combo Container?


20ft office and storage combo units, 20-foot combo containers, 20ft office and storage containers, and 20ft office and storage combo shipping containers are different ways of saying the same thing: 20ft units with dedicated space to store commercial items and tackle temporary work needs. 


Our 20ft office and storage combo units take the utility of our portable storage units and marry them with the efficiency of our temporary workspaces. They provide you with a portable, standalone container that can be immediately installed anywhere and tackles two critical commercial needs in one swoop. 


Like all of our portable storage and temporary workspaces, our 20ft office and storage containers are made from converted shipping containers. This design feature gives our 20ft office and storage combo units the strength and portability of a shipping container and the utility of a traditional commercial storage space. 


Like everything Mobile Mini stocks, our 20ft office and storage combo shipping containers seamlessly integrate with your jobsite. Most units fit inside a standard parking space!

When to Choose a 20ft office and Storage Combo Unit


At Mobile Mini, we consider ourselves jacks of all trades. We proudly serve over 20 industries and have customers in retail, hospitality, automotive, education, and construction. 

While we don’t play favorites, many of our customers use our containers to tackle:

  • Construction Storage and Temporary Work: Construction project managers love our 20ft office and storage combo units because they provide a space to house equipment, fragile and sensitive materials, and other essential construction supplies. They also double as a safe and quiet space to handle administrative tasks, meet with vendors, take breaks, and other activities. 
  • Hospitality Storage and Temporary Work: Restaurants and hotels use our 20-foot combo containers to store unused equipment, decor, and supplies. They also create space to handle customer check-in, bookkeeping, and other administrative tasks. 
  • Retail Storage and Temporary Work: Our retail customers love our 20ft office and storage combo units because they offer a space to house unused and seasonal inventory while simultaneously offering an off-site location for staff to sort through, organize, and track this inventory.
  • Education Storage and Temporary Work: Schools, universities, and colleges use our 20 foot combo containers to store books, tech, and other school materials and supplies. They also create an area for faculty to plan and complete administrative tasks without taking up valuable classroom and campus space.

Benefits of a 20ft Office and Storage Combo Shipping Container


We are hard-pressed to fit all of the benefits of our 20ft office and storage combo units in one list. But if we have to try, here are the top four benefits these units bring to our customers’ worksites:

  • Fully Weatherproof: All Mobile Mini storage and temporary work units, including our 20-foot combo containers, are made from 100% corrugated steel. Not only is corrugated steel one of the strongest metals on Earth, it’s also naturally weatherproof and made to withstand even the toughest storms. 
  • They’re Secure: Mobile Mini’s 20ft office and storage combo units come standard with our tri-cam locking system. These locks have been specially designed by our security team to integrate into our units and to offer protection that cannot be cut, tampered with, or picked. 
  • They’re Portable: Our 20ft office and storage containers may have shed their shipping container pasts, but that doesn’t mean they lost all traits of their previous lives. These units are highly portable and easily transported (while empty) from jobsite to jobsite without compromising their physical or structural integrity.
