Warehouse too small? When is reorganisation better than expansion?

How can you identify unused space in your warehouse?

A lack of space does not always mean that your warehouse has too little floor area. Sometimes the existing warehouse layout no longer matches the goods you store or the way your employees work.

Perhaps your product range has expanded, but the racks are still positioned exactly where they were several years ago. Or fast-moving products are stored far from the dispatch area, forcing employees to travel unnecessary distances.

Recurring bottlenecks can also indicate that your warehouse layout no longer meets your operational needs. Examples include aisles that are frequently blocked, insufficient space for temporary storage, or forklifts struggling to pass each other.

Before deciding to expand, it is therefore worth examining where available space is being lost and how much storage capacity you actually need.

How can you increase storage capacity without expanding your building?

There are several ways to create additional storage capacity without extending your warehouse. The most suitable solution depends on the available height, the goods being stored, and your logistics processes.

Make better use of the available height

In many warehouses, part of the available storage space above the existing racks remains unused. Taller pallet racking or a different racking configuration may allow you to make better use of this space.

A mezzanine floor or platform can also be an interesting option. It creates an additional usable level within the existing building.

Whether this is feasible depends on factors such as clear height, floor load capacity, building structure, and accessibility requirements. Fire safety and applicable regulations must also be taken into account.

Choose racking systems that require less floor space

Conventional pallet racking provides direct access to individual pallets, but it is not always the most space-efficient solution for every storage requirement.

If you store large quantities of pallets containing the same product, more compact storage systems may be worth considering. With push-back racking, pallets are stored several positions deep. These systems operate according to the LIFO principle (Last In, First Out), meaning that the last pallet stored is the first to be retrieved.

Mobile pallet racking and other dynamic storage systems may also offer opportunities.

However, higher storage density is not always the best solution. Product accessibility, stock turnover, and the material handling equipment used are equally important when choosing the right system.

Reduce walking and driving distances with a different layout

Additional storage capacity offers little value if it makes order picking or internal transport more difficult.

Consider the location of frequently requested products, the position of loading and unloading areas, and the routes employees travel every day. Sometimes repositioning the racks or adjusting aisle layouts delivers greater benefits than simply adding more storage locations.

The aim is not to fill every square metre, but to organise the available space so that storage and the movement of goods work efficiently together.

Get more out of your existing warehouse racking

New warehouse racking is not always necessary to make better use of your storage space. In some cases, existing racks can be adapted to suit your current storage requirements. For example, the distance between the beams can be adjusted to match the dimensions of your pallets, reducing unused space between storage levels.

Racking can also be dismantled and reinstalled in a different location. An adjusted configuration may create room for additional storage positions or improve walking and driving routes.

We assess which modifications are technically feasible and safe, which components can be reused, and where new racking is required. This allows you to make the most of your existing installation wherever possible, without unnecessarily replacing everything.

When is warehouse expansion necessary?

Not every space problem can be solved within an existing building.

If the available height is already fully utilised, storage capacity is consistently insufficient, or the building layout prevents further optimisation, a physical expansion or relocation may be necessary.

Future growth also plays an important role. If your inventory is expected to increase significantly, you want to avoid investing in a new warehouse layout that will become inadequate again within a short period.

That is why it is important to consider not only your current inventory, but also expected volumes, peak periods, and potential changes to your product range.

A warehouse analysis can help determine how much space is still available and where the limitations of your existing building lie. This helps you avoid investing in modifications that only solve your space problem temporarily.

Which costs less: warehouse reorganisation or expansion?

Reorganising a warehouse generally requires a different level of investment than physically expanding the building. However, comparing only the initial project costs does not provide the full picture.

When reorganising a warehouse, costs may include new or modified racking, dismantling, installation, potential floor and safety adjustments, and the temporary relocation of goods.

A physical expansion may also involve construction costs, permits, and modifications to the building infrastructure. The specific requirements depend on the project and its location.

It is also important to consider the impact on daily operations. A cheaper solution is not necessarily more cost-effective if employees subsequently need more time to move goods.

Therefore, compare not only the investment, but also the usable storage capacity, the efficiency of material flows, and the opportunities for future growth.

Can you reorganise your warehouse while it remains operational?

Reorganising a warehouse does not necessarily mean that all activities must come to a complete stop. With proper preparation, work can sometimes be carried out in phases.

This does, however, require clear agreements. Which areas need to be temporarily cleared? Where will goods be stored during the work? And when can racking be safely dismantled and reinstalled?

The schedule depends on the scale of the modifications and which operations need to continue during the project.

Our BMS project in Evergem demonstrates how warehouse reorganisation can work in practice. We reorganised the existing pallet racking and converted the original narrow aisles into wider ones. The new layout provides more manoeuvring space and better supports daily logistics operations. The work was carried out step by step, with limited disruption to everyday activities.

This example also shows that optimisation does not always mean fitting as many pallets as possible into the same floor area. Sometimes, improving the flow of goods is more important.

Find out how much space your warehouse still has to offer

Are you unsure whether expanding your warehouse is the best option? It makes sense to first explore what is possible within your existing space.

We can measure and analyse your warehouse to identify bottlenecks in the layout, storage systems, and daily operations. Based on these findings, we work with you to determine which adjustments would be worthwhile.

Our approach goes beyond simply installing new racking. Modifying or relocating existing storage systems, as well as the practical implementation of a warehouse reorganisation, may also form part of the solution.

This gives you a clearer understanding of your warehouse's potential before committing to a larger investment.
