Benefits of Storage and Office Container Units

Shipping container office-storage units offer a host of advantages over traditional brick-and-mortar structures. Let’s look at some of the benefits:

Quick turnaround time: You can get an office-storage combo shipping container delivered directly to your job site much faster than building a conventional structure. The quick turnaround time helps you save on additional labor costs and quickly jump to business.

Portability: Shipping containers come equipped with forklift pockets, making carrying a shipping container office-storage combo unit highly convenient. You can take your business or storage wherever you go.

Security: Storage containers have a weather-resistant build that makes them ideal for transporting cargo over long distances on rough seas. Once they are out of service, their sturdy structure provides reliable storage space safe from wind and climatic weathering, rodents, theft, or vandalism.

Easy-to-customize: The highly flexible design of a storage container provides the option to make certain modifications. You can add roll-up doors, security bars, lights and even create an insulated space.

Rent vs. Buy

Listed are below are a few factors to consider when deciding whether to rent or buy a shipping container:

Purpose of Use: Buying a shipping container is preferable if you plan on making significant modifications. Most rental companies offer pre-built containers, which minimizes your ability to make design changes. If you need more office space, renting a container is your best bet. Modern office containers come equipped with insulation, lights, flooring, and electrical fixtures.

Duration: Renting is a better option for individuals who plan on using their containers for five or more years. If you require additional time with the combo container office unit, you may find that purchasing is the way to go.

Cost Considerations: In general, renting involves much less upfront capital cost than buying a container. Renting is a good choice if you want to kickstart your business immediately without burning a hole in your pocket.

New vs. Old: The prices of shipping containers vary considerably depending upon their age, service conditions, and sizes. New containers can cost twice as much as old containers. However, if you plan on creating stacked offices or innovative structures, go for purchasing a new container. On the other hand, rented containers may have better exteriors as rental companies generally perform routine upkeep after every service.

Frequency of Moving: Most container providers do not include delivery charges in the container pricing. For frequent movers, renting is a great option. You can return your old offices and rent a new one from a service provider near your location. If you plan to install containers in one place, you must also consider the cost of leasing or buying the land for container installation.

Maintenance: When you rent a container, you defer most maintenance responsibilities to the rental company. However, when buying a container, you are responsible for ensuring adequate maintenance and upkeep of the container, which can add to the overall lifetime cost.

Portable Storage Combo Container FAQ

What are office containers?

Office containers are a modern, cost-efficient, and highly portable alternative to traditional office buildings. Shipping container companies modify used shipping containers to build office spaces. These buildings use the container structure on the outside, while the interiors undergo complete modifications to fit utilities such as work tables, insulation, air conditioning, flooring, and electrical fixtures.

Do I have to prepare the site to set up office and storage containers?

You should also consider the following factors before delivery:

  • Duration for which you need the unit. A longer duration requires more site prep.
  • Firm and smooth ground base
  • Susceptibility to flooding
  • Access road large enough for a semi-truck to reach your property

Your site will need a straight-line clearance of 60 feet for 20-foot units and 100 feet for 40-foot units, with a 14-foot height clearance. Talk to one of our experts for help selecting the right truck from our fleet for a hassle-free delivery.

How much does a container office cost?

For standard 20- and 40-foot mobile office-storage combo units, your monthly rental price depends on various factors, such as size, availability, modifications, and whether the unit is brand-new or used.

You can also purchase a combo shipping container if you wish to make your own design modifications.

Do I need planning permission for a storage container office?

Shipping containers generally come in the following ISO sizes: 10 ft., 20 ft., 24 ft., and 40ft. The height and width of all shipping containers are the same, though lengths will differ. ISO-size containers have a standard width and height of 8 ft. and 8 ft. 6 in., respectively, while their lengths can extend to 10 ft., 20 ft., 24 ft., or 40ft.
