Extra wide shipping containers offer a compelling solution for businesses needing expanded storage and flexible workspace.
These modified units are created by combining two or more standard shipping containers, removing their side walls and joining them together to create a significantly larger area of open space. This increased width is the primary advantage, allowing for the storage of bulky items, large equipment or a greater volume of goods than standard containers can accommodate.
The resulting storage volume depends on the size and number of original containers used, offering flexibility to meet various storage requirements. For instance, combining two 40-foot containers creates a much wider space than combining two 20-foot containers. This adaptability in size makes extra wide containers a valuable asset for a diverse range of businesses.
In this blog, we’ll discuss how extra wide shipping containers’ uninterrupted space created by joining containers is ideal for uses beyond simple storage.

The Purpose of Extra Wide Shipping Containers
The purpose of extra wide shipping containers centers around providing scalable and adaptable storage. They are particularly beneficial for businesses dealing with large or oversized items, such as those in construction, agriculture, aerospace and manufacturing. These industries often handle equipment, materials, or products that exceed the storage dimensions of a standard container. Extra wide containers provide the necessary space for safe and efficient storage of these oversized items, eliminating the need for disassembly or specialized storage solutions.
By combining multiple containers, businesses can create spacious interiors suitable for workshops, studios or even temporary retail spaces, facilitating easy movement of materials and personnel.
The open layout allows for efficient workflow and the accommodation of large machinery or workbenches. Businesses experiencing growth or seasonal fluctuations in inventory can also benefit from the increased storage volume, offering a cost-effective alternative to constructing a new warehouse or leasing additional space. This scalability allows businesses to adapt quickly to changing demands without significant capital investment.

Modifying a Mini Warehouse
Extra wide shipping containers can effectively function as mini-warehouses. Their robust construction and customizable nature make them a viable alternative to traditional small warehouse buildings.
Businesses can further enhance their functionality by adding features like insulation to regulate interior temperature, protecting stored goods from extreme weather. This is particularly important for temperature-sensitive items or in regions with harsh climates. Electrical wiring can be installed to power tools, climate control systems and other electrical equipment, making the container a fully functional workspace.
Additional doors and windows can improve accessibility and ventilation, creating a more comfortable and practical environment. Shelving and racking systems can maximize the use of available space and facilitate organization, allowing businesses to efficiently manage their inventory. Security features, such as locks can protect valuable inventory from theft and vandalism, providing peace of mind.
By incorporating these modifications, businesses can transform extra wide shipping containers into functional and secure mini-warehouses tailored to their specific needs, often at a fraction of the cost of traditional construction.
How to Buy & Modify Extra Wide Shipping Containers
Acquiring and modifying extra wide shipping containers with Southwest Mobile Storage involves several key steps:
1. Obtaining a Container
First, you need to source the containers themselves, which can be purchased new or used from various suppliers.
Used containers are generally more affordable, but it’s crucial to inspect them carefully for damage or rust. Factors like the container’s history, its previous cargo and the extent of any repairs should be considered. One-trip containers are generally preferred for modification purposes because of they have only minor dings and dents from their limited time spent at port and sea. So, they’ve endured less wear and tear than used containers. Their corrugation is straight, the floor joists are straight, and the roof is flat so it won’t hold rust-causing water.
Next, finding a reputable modifier is essential. Modifying shipping containers requires specialized skills and equipment, so working with an experienced company is highly recommended. They can advise on structural integrity, necessary reinforcements and the best methods for incorporating desired features.
Southwest Mobile Storage is an expert in container modification. We have a team of fabricators with decades of combined experience, and a large fabrication facility that makes it easy for us to customize extra-wide shipping containers to whatever specifications you need.
2. Design a Layout
Then, you’ll need to design the layout, determining the desired dimensions and layout of the extra wide container based on your specific storage needs. This involves considering the types of items to be stored, the required access points and the overall workflow.
Depending on your location and intended use, obtaining necessary permits may be required before modifying or placing the container on your property. Local building codes and zoning regulations should be consulted before modification begins.
3. Modifying and Delivering Extra Wide Shipping Containers
Once permits are secured, the modification process can begin, typically involving removing the side walls, reinforcing the structure, and adding any desired features. This may include welding, cutting, and other specialized techniques.
Finally, you’ll need to arrange for the delivery and installation of the modified container to your site. When we deliver extra wide-shipping containers, we deliver them in two parts, then assemble them together on site. This process can take anywhere from a few hours to two days to complete. Containers with HVAC systems and electrical hookups take longer than containers with simpler modifications, for example.
Additional Uses for Extra Wide Shipping Containers

Beyond storage and mini-warehouses, extra wide shipping containers find applications in various other sectors.
The open layout provides ample space for workshops, allowing for creative endeavors and collaborative projects. Even in agriculture, extra wide containers can be adapted for use as storage sheds, animal shelters or greenhouses, providing a durable and versatile solution for agricultural needs.
Southwest Mobile Storage’s sister company, Pure Greens Container Farms, uses extra wide shipping containers to create hub units that allow hydroponic growers to control their entire farms from one location.
Summary
Extra wide shipping containers offer a versatile and cost-effective solution for businesses seeking expanded storage capacity and flexible workspace options. Their adaptability and durability make them suitable for a wide range of applications, from storing oversized equipment to creating temporary retail spaces.
The ability to customize these containers with insulation, electrical wiring and other features further enhances their functionality. By carefully planning and executing the modification process, businesses can leverage the benefits of extra wide shipping containers to optimize their operations and achieve their storage goals.
