Basic Storage Structures
While we call this unit a basic storage structure, it’s far more than a simple box. These versatile units can be readily adapted for diverse use cases with the addition of key add-ons.
For example, incorporating the popular Lift Panel instantly transforms your structure into a functional supply station, efficient ticket booth, or vibrant retail pop-up.

Designed to be a smart, portable storage solution, these units offer an excellent alternative to traditional shipping containers, meeting a wide range of operational needs.

LED Modules
One reason we wanted to write this modular structure buyers guide is because our LED modules are pretty different from any other product that’s out on the market, and we wanted to give you some ideas of how you can use one!
This portable solution amplifies your presence anywhere you go. You get a dynamic solution for trade show displays or even full-sized, programmable digital billboards.
Build buzz and spark curiosity just about anywhere!

Check out this video which shows you how we use these structures as billboards on our own property.
When to choose:
- When you want to transform your display presence, like replacing an unsightly tech booth with a sound and light booth that becomes part of the show.
- When you need to display timely and critical information from your command center, aid station, or public information point.
- When you run retail pop-up stores and want to advertise far and wide, leveraging an LED billboard that can easily be seen from the Interstate.
- When you need a highly visible and mobile platform for advertising, public service announcement, or branding at events.
Recommended Add-Ons:
This unit is already fully stacked for its function, which means we don’t recommend any add-ons for this one. There’s room on the inside to store some items, and you can combine these modules with other structure to create the solution that works best for you.
Combo Structures
True innovation often comes from combining strengths. While our individual modular structures offer exceptional utility, the real power lies in their ability to seamlessly integrate and scale in order to meet your most ambitious goals.
Thanks to our patented corner caster and corner connector system, each structure can be effortlessly stacked, linked, and securely locked into place. This intuitive design ensures quick assembly and robust stability for any configuration.
The possibilities are limitless.
You can mix and match all three of our structure types to craft highly specialized solutions for virtually any application. Imagine combining a secure storage unit (with a man door for access) with multiple additional units for expansive floor and inventory space, all complemented by an attention-grabbing LED module to create an epic, high-impact pop-up retail store.
The walls between may be removed to create a seamless space.
Determining How Many Structures You Need
Our structures provide unmatched flexibility to scale from compact setups to expansive facilities. Consider these examples of what you can build:
- Two linked structures: ideal for an efficient locker room or compact office.
- Four linked structures: forms a spacious office large enough for multiple workstations, equipment, and printers.
- Sixteen linked structures: can create a complete modular warehouse.
To help you with your planning, remember that a 13’ structure offers ~85 ft² of usable floor space, and a 19’ structure provides ~126.48 ft². Keep these figures and your specific spatial requirements in mind as you calculate your optimal setup.
FAQ
When should I choose a high-cube model?
If you have taller items to store, a high cube is worth considering.
How do I plan connected modules, so they function as one useful space?
Start with the activities that need to happen inside, then arrange the modules around them.
For a pop-up retail layout, for example, sketch the customer entrance, display area, checkout, and inventory storage. For a connected office, identify workstations, shared equipment, and the routes people will use between them. This makes the number of modules a result of your plan—not a substitute for one.
Discuss the proposed wall openings, connections, and entry points with GoodMFG® before finalizing the order. The goal is to combine the right functions while keeping the finished space convenient to use.
What information should I provide when requesting a quote?
Tell your dealer about your intended use, available site space, preferred size, and any furniture, equipment, or inventory the unit needs to accommodate.
Key Takeaways
- Start with the structure’s main job. Basic storage units offer a flexible starting point for inventory and equipment, modular office building provide dedicated workspace, and LED modules support advertising, event displays, and public information.
- Choose dimensions around your layout. Compare interior length, width, and height with the items and activities you need to accommodate. High-cube models add overhead space. Longer or connected structures provide additional room.
- Combine models for a more complete solution. Storage, office, and LED modules can be incorporated into a coordinated setup, bringing workspace, inventory, and visibility together.
