How Mezzanine Warehouse Storage Can Safely Double Capacity

How Mezzanine Warehouse Storage Can Safely Double Capacity
Many warehouses in the UK are running out of floor space. Yet stock volumes are constantly on the rise, and demand for logistics facilities is changing. Research by the Logistics Manager shows that space limitations are a big challenge in warehousing. It found that 29% of warehousing professionals identified this problem. Also, data from the Office for National Statistics shows that the number of UK warehouses has doubled over the past decade. Mezzanine warehouse storage utilises empty vertical space. It creates functional, load-bearing floors that support ongoing operations.
A well-designed mezzanine introduces a safe upper level that expands space while the warehouse remains in active use. It supports storage, picking, and packing, and meets safety and structural standards.
This article explains how mezzanines increase capacity. It also covers the safety principles that govern their design and the factors that guide a compliant installation.
Convert Unused Headroom Into Safe Warehouse Floor Space
A mezzanine is an intermediate steel platform installed between the ground floor and the ceiling void. Many warehouses operate with substantial unused headroom. Yet, a mezzanine allows this vertical space to become a productive area for pallet racking, bulk storage, or expanded picking zones. This helps reduce congestion on the ground floor and creates room for more organised stock movement.
A well-designed mezzanine supports predictable load performance. Under Approved Document A (Structure), structural stability must be demonstrated through appropriate calculations. A well-planned mezzanine considers point loads and the distribution of weight on the steel structure. In doing so, this helps the platform perform reliably under daily operational use. It also creates a stable environment for staff and helps keep aisles clear and efficient.
In capacity terms, the additional floor area created by a mezzanine often supports three core improvements:
- A dedicated upper deck for palletised or bulk goods
- Defined areas for packing, sorting, or returns handling
- Multi-tier configurations in high-bay warehouses, where height allows
These changes increase usable capacity in the same area and promote a more sensible layout. For more information, check the Health and Safety Executive’s (HSE) Warehousing and Storage guidance (HSG 76). Better use of vertical space in the warehouse can reduce congestion and improve the flow of operations.
For examples of how warehouse space can be planned and organised, you can explore the warehouse section of the workplace hub.
Designing a Safe, Fully Compliant Mezzanine From Day One
A mezzanine must be designed to support the intended load, particularly in warehouses. In such spaces, palletised goods and bulk items place significant pressure on the structure. To ensure stability, the design must adhere to the structural requirements outlined in Approved Document A. These requirements help assess point loads, distributed loads, and overall performance. This keeps the platform reliable during operation.
Fire safety is also essential, and Approved Document B outlines the measures required to:
- Protect escape routes
- Fire resistance
- Detection systems
- Compartmentation
Mezzanines in warehouse buildings must include key fire safety measures. These measures are smoke detection systems and proper escape routes. A compliant mezzanine has secure staircases, handrails, pallet gates, and adequate fire protection for safe use. The HSE provides extra guidance on warehouse layout and safe access. This ensures walkways stay clear, lighting is good, and staff can move around safely.
To limit disruption, our team completes much of the fabrication work off-site. This reduces time spent on the warehouse floor and allows operations to continue during installation. On-site work happens in clear stages. First, we ensure the structure is secure. Then, we integrate lighting, electrics, and flooring.

Increase Capacity Without the Cost & Disruption of Moving
Rising industrial rents in the UK continue to place pressure on businesses that require additional space. Colliers reports that the UK’s average prime rent for mid-box and multi-let industrial units hit £15.55 per square foot in June 2025. This marks a 4.0% increase from last year. Additionally, research predicts that industrial real estate rents will increase by 3.2% annually from 2024 to 2028.
Relocating to a larger facility can involve higher lease costs, new fit-out work, and operational downtime. Mezzanine warehouse storage allows organisations to expand usable space within their existing building. This helps them sidestep the costs and hassles of moving to a new site.
A mezzanine also supports a more efficient layout. When teams separate storage, picking, and packing, they can move stock more efficiently. This change also helps lessen congestion in busy spots. This makes day-to-day tasks easier to manage and allows facilities to maintain clear routes for equipment and staff. As operations expand, mezzanine systems can be adjusted or reconfigured to accommodate the new needs.
