A warehouse can run out of useful space long before every square metre is occupied. The problem often lies in how stock is stored, how often staff need to retrieve it, and how much room conventional shelving consumes. When picking routes become longer and popular items are difficult to reach, adding more floor space may not be the smartest first move.
One option is to rethink storage vertically. A vertical lift module system brings stored items to an access point rather than requiring staff to walk along rows of shelves. This approach can be useful for operations handling many small parts, tools or components, especially when floor space is limited. The real question is whether the storage method fits your inventory and daily workflow.
Look Beyond Floor Space
Traditional shelving makes stock visible and accessible, but it also spreads inventory across a large footprint. As stock levels grow, businesses may add more aisles, relocate workstations or rent additional space. Each change can create new movement and handling costs.
Vertical storage changes that equation by using available height. Instead of spreading shelves across the floor, a lift-based unit stores items in a compact structure and delivers selected trays to an operator. However, the height of your building alone does not determine suitability. Ceiling obstructions, floor loading limits, access requirements and installation clearances all affect how much usable capacity you gain.
The best starting point is to measure the space you can actually use, not simply the distance from floor to ceiling. A tall unit that cannot accommodate structural beams or required maintenance access may offer less practical capacity than expected.
Match Storage to Your Stock
A storage system works best when its design reflects the items it holds. Small electronic components, maintenance parts and packaged accessories may suit tray-based storage because they can be organised into labelled compartments. Long materials, oversized cartons and irregular equipment may need a different arrangement.
Before selecting a system, examine three features of your inventory:
- Item dimensions: Check the largest and smallest items, including packaging.
- Retrieval frequency: Identify which products staff collect dozens of times a day and which move only occasionally.
- Handling requirements: Consider weight limits, fragile goods and any special storage conditions.
This review can reveal a costly mistake: choosing capacity based on the number of items alone. A unit may hold thousands of small components yet prove unsuitable for bulky products that require wide access. Measure the actual storage containers and account for space needed to separate different stock-keeping units.
Calculate the Real Trade Off
Consider a warehouse with 120 square metres of shelving spread across several aisles. Suppose a redesigned layout could consolidate the same suitable inventory into a vertical storage area occupying 30 square metres. The difference would be 90 square metres of floor footprint, although the actual result would depend on the unit’s dimensions, tray configuration and the inventory selected.
That calculation is only the beginning. You must also account for installation costs, maintenance, power requirements, staff training and any changes needed to integrate the equipment into existing processes. Savings from reduced walking and better space utilisation may justify the investment, but the numbers should support that conclusion.
A useful decision rule is to compare the total cost of ownership over a realistic period, such as five years. Include the purchase and installation costs, expected servicing, labour requirements and the value of floor space released. Compare these figures with the cost of keeping the existing arrangement or expanding the warehouse. This creates a clearer basis for deciding than comparing equipment prices alone.
Improve Picking Before Buying
New storage equipment cannot compensate for poorly organised inventory. If staff frequently search for misplaced items, introducing a more compact system may simply move the confusion into a smaller area.
Start by reviewing recent picking activity. Identify the products most often requested together, the items that cause delays and the stock that occupies valuable space despite rarely moving. Frequently accessed products should be positioned and grouped to support the way orders are assembled.
A simple trial can help. Track the time needed to complete a sample of picking tasks under the current layout, then estimate how those tasks would change with the proposed storage arrangement. Include replenishment, exception handling and access to neighbouring workstations. A system that speeds up retrieval but creates a bottleneck during replenishment may not improve overall productivity.
Plan for Future Demand
Storage decisions should account for more than today’s stock levels. Seasonal peaks, new product lines and changes in order size can all affect how much capacity an operation needs. A design that works well now may become restrictive if every tray is filled and no room remains for new inventory.
Ask suppliers to explain how capacity can be adjusted, which tray sizes are available and what happens when stored items exceed the original dimensions. Also clarify service arrangements, expected maintenance downtime and how staff can access essential stock if the equipment is temporarily unavailable.

The strongest warehouse layout is not necessarily the one that stores the most items in the smallest area. It is the one that balances capacity, retrieval speed, safety and operating cost. By measuring usable height, studying real picking patterns and calculating the full cost of ownership, you can make better use of existing space while building a storage plan that remains practical as demand changes.
