What Is A Mezzanine Floor?

A mezzanine floor is an intermediate floor constructed in any storey, according to the Gazette of Western Australian Government. It is usually within a building, often open to the floor below. It's not counted among the main floors of a building and is typically installed to increase the available floor space. Mezzanine floors are a versatile solution in both industrial settings and commercial environments, offering a cost-effective way to expand space without the need for relocation or major structural changes to the existing structure.


What are Mezzanine flooring made of?

Steel mezzanine

Steel mezzanines are popular due to their strength and durability. They are ideal for heavy loads and can be used in various settings, including warehouses and industrial mezzanines. The steel structure ensures that the mezzanine floor is built to last, providing a robust and reliable additional floor.

Concrete mezzanine

Concrete mezzanines offer excellent stability and fire resistance. They are often used in industrial mezzanine floor applications where a solid and durable floor slab is required. This type of mezzanine floor construction is ideal for supporting heavy machinery and high-density storage.

Rack mezzanine

Rack mezzanines integrate shelving into the mezzanine structure, making them perfect for storage space optimization. They are commonly used in warehouse mezzanine floors, allowing for efficient use of vertical space and easy access to stored items.

What is a mezzanine floor used for?

Storage mezzanine floor

Storage mezzanines are used to increase warehouse floor space, providing additional areas for storing inventory, pallets, and other materials. They are a cost-effective solution for businesses needing extra storage space without expanding their existing footprint.

Work platform mezzanine

These mezzanines create an additional workspace or production floor. They are often used in manufacturing settings, where they provide extra space for machinery, workstations, or assembly areas.

Portable mezzanine

Portable mezzanines offer flexibility, as they can be moved or reconfigured as needed. This type of mezzanine floor is ideal for businesses with changing space requirements.

Retail mezzanine floor

Retail mezzanines are used to expand floor space within retail environments, providing additional areas for product displays or customer services. They enhance the shopping experience by effectively utilising the available space.

Office mezzanine floor

Office mezzanine floors create extra office space in warehouses or industrial buildings. They are an excellent way to add office areas without compromising the existing floor space for operational activities.

Other Mezzanine Floor Components

Mezzanine guardrails

Guardrails are essential for safety, ensuring that people are protected from falls when using the mezzanine.

Mezzanine Stairs

Stairs provide access to the mezzanine level. They must comply with building regulations and are designed to be safe and easy to navigate.

Mezzanine alternating tread stairs

These stairs are a space-saving option, ideal for areas where traditional staircase installation is not feasible due to space constraints.

Tips for building a mezzanine floor

When planning to install a mezzanine, consider the following:

  • Ensure the design complies with building regulations and is suited to the intended use of the mezzanine.
  • Choose the right materials (steel, concrete, or rack) based on your specific needs, such as load capacity and intended use.
  • Factor in the installation of essential components like guardrails, stairs, and, if necessary, alternating tread stairs for safety and accessibility.
  • Work with a professional mezzanine designer and installer to ensure that your mezzanine floor project is executed efficiently and safely.

Incorporating a mezzanine floor into your workspace can significantly enhance the functionality and efficiency of your existing structure. Whether it’s for storage, additional office space, or a new production area, a well-designed mezzanine floor can provide numerous benefits without the high costs and inconvenience of relocating or extensive renovations.

Mezzanine Meaning FAQs

What is the difference between a balcony and a mezzanine?

A balcony is an outdoor extension of a building, typically accessible from an upper floor, and is enclosed by a railing or balustrade. In contrast, a mezzanine is an intermediate floor inside a building, often partially open to the double-height ceiling area below. Unlike a balcony, a mezzanine is used to increase the indoor floor space of a building, such as adding extra storage space or office space within a warehouse or industrial setting.

What is the difference between a loft and a mezzanine?

A loft usually refers to an upper floor or attic in a building, directly under the roof, used either for living space or storage. A mezzanine, on the other hand, is an intermediate floor, open to the floor below, and does not extend over the whole floor space of the building. While lofts typically convert the entire upper space, mezzanines create a partial floor within a larger room, often used in warehouse mezzanine applications or to add office mezzanine floors.

How much does it cost to build a mezzanine floor?

The cost of building a mezzanine floor can vary widely depending on factors such as the size of the mezzanine, materials used (like steel or concrete), complexity of the design, and the specific requirements of the space. Additional factors like the installation of stairs, guardrails, and the need for compliance with building regulations can also affect the cost. Generally, mezzanine floor construction is a cost-effective way to increase floor space compared to traditional expansions or relocation.

Is mezzanine floor safe?

Yes, when designed and installed correctly, following building regulations and standards, mezzanine floors are safe. Key safety features include sturdy construction materials, proper load capacity design, secure guardrails, and safe access points like well-designed mezzanine stairs. Regular inspections and maintenance are also crucial to ensure ongoing safety.

Can you put a bathroom on a mezzanine floor?

It is possible to install a bathroom on a mezzanine floor, but it requires careful planning and design. Considerations include the weight capacity of the mezzanine structure, plumbing requirements, and adherence to building codes. Professional assessment and installation are recommended to ensure safety and functionality.

What are the hazards of the mezzanine floor?

Common hazards associated with mezzanine floors include falls from heights, structural overloading, and poor access or egress in emergencies. To mitigate these risks, it’s important to ensure proper design and installation of guardrails, adherence to load capacity specifications, and the provision of safe and accessible staircases. Regular safety audits and compliance with workplace safety standards are also essential.

Can I build a mezzanine without planning permission?

The need for planning permission for a mezzanine floor varies based on local regulations and the scope of the project. In many cases, mezzanines built for storage or as part of industrial use may not require planning permission, but it’s always advisable to check with local authorities. Factors like changes to the external appearance of the building, intended use, and impact on the surrounding environment can influence the need for permission.

What is the minimum height for a mezzanine floor in Australia?

In Australia, the Building Code stipulates that the minimum height for a room, including mezzanines, is generally 2.4 meters. However, for non-habitable rooms like storage spaces, the minimum height can be reduced to 2.1 meters. It’s important to consult the specific building codes and regulations relevant to the area and intended use of the mezzanine to ensure compliance.
