How to Increase Warehouse Capacity Without Expanding
Most warehouse space problems don’t begin with the building.
They begin with how the space is used.
A major pharmaceutical logistics operation recently discovered this first-hand when increasing SKU counts and rising order volumes began placing serious pressure on their cold-room distribution facility.
At first glance, the problem seemed obvious: the warehouse was running out of space.
But when ProMHS analysed the operation more closely, the real issue became clear.
It wasn’t a space problem.
It was a storage density problem.
The Situation: When Traditional Storage Hits Its Limits
The facility handled large volumes of temperature-controlled pharmaceutical products across a multi-client distribution environment. Like many operations managing thousands of small and medium SKUs, the warehouse relied heavily on traditional racking and shelving configurations.
Over time, several inefficiencies emerged:
- Valuable vertical space between rack beams remained unused
- Pick locations were spread across multiple levels
- High-bay equipment was frequently required for picking
- Picker travel distances increased as SKU counts grew
- Order consolidation added additional labour time
Although the racking system itself was well designed, the way small items were stored meant that large portions of available storage volume were effectively unused.
As the business continued to grow, expansion of the refrigerated facility appeared inevitable.
Instead of expanding the building, ProMHS asked a different question:
How much storage capacity already exists inside the current footprint?
The Intervention: Turning AIRHOUSE Into WAREHOUSE
The solution was the implementation of Storeganizer, a high-density vertical pocket storage system designed for small and medium-sized items.
Storeganizer uses suspended textile pocket columns that hang inside standard pallet racking. These vertical pocket arrays transform unused vertical space into organised, accessible pick locations.
Rather than spreading products across wide shelving areas, hundreds of SKUs can be concentrated within a compact storage zone.
This approach dramatically increases storage density while keeping picking fully manual and highly accessible.
Because the system integrates directly into existing pallet racking, the installation required no structural changes to the warehouse and no automation infrastructure.
The Result: Measurable Operational Gains
Following the implementation, the warehouse achieved several measurable improvements.
✔ Storage Density
Pick locations increased dramatically within the same rack footprint, allowing significantly more SKUs to be stored in the same space.
✔ Travel Time Reduction
By concentrating hundreds of pick faces into dense pocket arrays, picker travel distances were reduced by more than 40%.
✔ Productivity Improvement
The combination of shorter travel distances and better product visibility resulted in order-picking productivity improvements of approximately 25%.
✔ Additional Pallet Storage
By relocating small-item storage into the high-density system, the operation also freed up approximately 200 additional pallet locations elsewhere in the warehouse.
In total, the facility gained substantial usable storage capacity without expanding the building or introducing complex automation.
What Changed on the Warehouse Floor
While the technical metrics were impressive, the most noticeable improvements were experienced by the warehouse team.
Storeganizer’s structured pocket layout improves visibility and organisation, making it easier for operators to locate items quickly.
One team member explained:
“We pick faster because everything is easier to see. The pockets are structured and grouped logically. You don’t waste time searching — you grab and move.”
Improved visibility reduces search time.
Reduced search time improves speed.
Better organisation creates a smoother workflow.
Why This Matters for Modern Warehousing
Pharmaceutical distribution centres, 3PL operators and eCommerce fulfilment facilities are all facing similar pressures:
- Growing SKU counts
- Increasing compliance requirements
- Rising labour costs
- Limited warehouse expansion opportunities
In many cases, the most effective solution is not expanding the building, but improving how existing space is used.
High-density storage systems like Storeganizer allow operations to unlock unused vertical capacity while maintaining operational flexibility.
Because the system is fully manual and requires no power input, it also supports more sustainable warehouse design by avoiding the energy and infrastructure requirements associated with large-scale automation.
Optimisation Instead of Expansion
This pharmaceutical distribution centre did not need more square metres.
It needed smarter storage.
By partnering with ProMHS and implementing Storeganizer, the operation unlocked significant additional capacity, reduced travel time and improved productivity — all within its existing warehouse footprint.
It’s a reminder that in modern warehousing, the most valuable space is often the space you already have.
