SELF-STORAGE EXPANSION SOLUTIONS
Turn More Space Into More Revenue
Modular storage systems designed to increase capacity, unlock space, and drive revenue.
FlatBox Solutions by Modular Building Solutions
In self-storage, growth is simple in theory—more rentable units means more revenue. But actually adding those units is where most operators get stuck. Traditional expansion takes time, requires significant capital, and often disrupts the customers you already have. FlatBox Solutions by Modular Building Solutions gives you a more practical way to grow.
Instead of waiting on long build timelines, you can add capacity quickly, place units exactly where they make sense, and expand based on real demand—not projections. It’s a faster, more flexible way to increase revenue without overbuilding or overcommitting.
WHAT HOLDS MOST FACILITIES BACK
Expansion Isn’t as Simple as It Should Be
Adding units should be straightforward—but traditional construction turns it into a slow, expensive process that delays your ability to generate revenue.
FlatBox removes that bottleneck, allowing you to move at the pace your business actually needs.
There’s Revenue Sitting Idle on Your Property
Most facilities have areas that aren’t producing income—edges of the site, unused land, or awkward layouts that are difficult to build on.
FlatBox units give you a way to activate those areas quickly, without reworking your entire property.
Big Capital Projects Carry Big Risk
Traditional builds require committing significant capital before you know how demand will perform.
FlatBox gives you a way to grow incrementally, reducing risk while still increasing capacity.
Growth Shouldn’t Disrupt Your Current Tenants
Construction can interfere with access, create noise, and impact the experience for existing renters.
FlatBox units are designed to be deployed with minimal disruption, so your facility keeps running smoothly while you expand.
Demand Changes Faster Than Build Timelines
Customer demand isn’t fixed. Unit sizes, occupancy rates, and seasonal trends all shift over time. Locking into a large expansion upfront can leave you with the wrong mix. FlatBox allows you to adjust as demand evolves, instead of guessing months in advance.
A BETTER WAY TO ADD UNITS
Built for How Self-Storage Actually Grows
Most facilities don’t expand all at once—they grow over time. FlatBox is designed for that reality.
Instead of a one-time build, you can expand in phases, test different unit configurations, and refine your layout based on what’s actually working.
Bring Units Online Faster
FlatBox units can be deployed quickly, allowing you to start generating revenue without waiting through long construction cycles.
Expand on Your Timeline
Add capacity when demand supports it—not all at once—so your growth stays aligned with occupancy.
Make Smarter Use of Your Space
Turn underutilized areas into rentable inventory without major site work or permanent changes.
Keep Operations Running Smoothly
Expand your facility without creating disruptions that impact your current tenants.

Designed Around Your Layout, Not a Fixed Plan
Every self-storage property is different. Layout, available space, and customer demand all play a role in how your facility should grow. FlatBox gives you the flexibility to build a setup that actually fits your property.
Whether you’re adding a small number of units to test demand or expanding across your site, you can choose from a range of storage sizes and configurations designed to work within your existing footprint.
Instead of committing to a rigid expansion plan, you can scale gradually, refine your unit mix, and respond to your market as it evolves.
That flexibility is what allows you to grow more efficiently—and more profitably over time.
