Mezzanine Floors

Crafting The Ideal Workspace!

Mezzanine Capabilities

Mezzanine floors offer an ideal resolution when you are seeking to:

  • Boost capacity by as much as 50% by unlocking additional workspace opportunities.
  • Enhance organisational efficiency and workflow through designated zones for various functions.
  • Opt for this cost-effective alternative to building expansions or relocating.
  • Benefit from an entirely bespoke design which precisely meets the unique needs of your business.

    The Problem Solver

    The Common Problems the mezzanines solve:

    Without the acquirement of additional square footage, here’s how a mezzanine installation can make life in the workspace easier when faced with these space related problems….

    Running out of space: Limitations in space may emerge as the workforce expands and business activity increases. Yet, the duplication of floor space achieved through a mezzanine can relieve this pressure without the need for horizontal expansion.

    Insufficient Storage and organisation: By adding an extra level, mezzanines increase storage capacity and improve organisation. This leads to enhanced inventory management, streamlined workflows, and increased accessibility.

    Lack of dedicated workspace: The additional space a mezzanine floor creates allows for departments and activities to be compartmentalised and purposely configured to improve workflow.

    What Is A Mezzanine Floor?

    Derived from the Italian term “mezzanino,” the mezzanine floor constitutes an elevated floor constructed within an existing building to create a level above the original ground floor level.

    Effectively, this is a solution which divides a single vertical space into two functional areas through its intermediate positioning. The floor is upheld by columns, providing access to both the platform level and the space beneath it. The upper level can extend to nearly encompass the entire room’s footprint, and with sufficient headroom, it can also be constructed upwards, forming a multi-story structure.

    The purpose of the mezzanine floor is to use all available space within your business premises intelligently, without the cost or disruption of extending the building or relocating, and that’s exactly what it does

    Why go the long way round

    “Our retail mezzanine floors have doubled our space in very short time. WSL provide a fast turnaround. They are very friendly and wonderful people to work with and are always there from start to finish”

    Lunds of Otley

    “The mezzanine looks great and has fitted into our scheme very well. We also completed reciprocal work for WSL during their office mezzanine floor project for channel 4 in Leeds, so it’s nice that have been able to assist each other”

    Mezzanine Floor Components


    Generally, a mezzanine floor structure is constructed of four main components:

    • Columns – reaching from the floor to the base of the mezzanine. The number and type of the columns will have been stipulated in the planning and design stages.
    • Primary steels or beams – the primary beams are usually made from UB Sections on a standard warehouse floor, though this will depend on the weight bearing requirements of the floor.
    • Secondary steels or purlins – These are fixed to the primary steels, bearing the weight of the mezzanine flooring. The number and type of purlins will again depend on the decisions made in the planning stage, including the amount of deflection expected for the floor.
    • Decking – Placed on top of the purlins to form a solid floor. 38mm P6 chipboard is standard flooring, though there are a wide variety of different options including moisture resistant.

    Mezzanine Floor Access Features

    Alongside the mezzanine floor, we work closely with you to understand the range of ancillaries required to support the efficient & safe use of your mezzanine floor.

    There are numerous ways to safely transport goods and people too and from a mezzanine floor level and the most suitable methods will largely depend on the functions carried out on the mezzanine platform. Access features include:

    Not used

    However the mezzanine level is used, a staircase is the easiest and simplest form of human access. Providing they meet UK standards, staircases vary in terms of colour, material and shape and can be designed to add style as well as practicality to your mezzanine floor. This presents an opportunity for those using a mezzanine for retail or office purposes to create an attractive mezzanine staircase feature


    There are two types of lifts, a goods lift and a passenger lift. In addition to stairway access, the passenger lift is ideal if disabled access is a priority or if your just looking for extra convenience. The goods lift is purposely designed to take the weight of heavy goods so they can be transported safety to and from the mezzanine levels. The goods are placed in the lift on one level then collected on arrival at the level intended which works even better with an operator at each level working together.

    Pallet Gates

    Positioned at the edge of the mezzanine level a pallet gate is cleverly designed to accept pallets onto the platform having been placed by the fork lift truck from below. The pallet gate opens to allow the pallet access and closes once placed whilst ensuring edge protection throughout the process.


    Using gravity a chute transports hand held items from upper to lower levels very quickly and easily making this an ideal solution when looking for speed and efficiency.


    These powered belts move continuously transporting goods between the mezzanine levels. The conveyor does all the work once the item has been placed and can be implemented to suit the size and weight of your inventory.

    Mezzanine Floor Edge Protection

    A mezzanine floor is an upper level platform therefore it’s needless to say that edge protection is an essential part of the design and structure. Fitted to secure all exposed edges along the perimeters of the floor level and staircase, edge protection acts as a barrier to prevent people or items from falling over the edge. Whilst any mezzanine platform will carry the risk of falling, for some environments, certain factors such as vehicle movement or children being present means the risks become much greater. In order to minimise those additional risks it’s important to be guided by UK Building Regulations when choosing the components, configuration and structural strength loadings of your edge protection. Or you can leave this extra consideration with your WSL Design Technician whose daily role in mezzanine floor design mean the standards set out by UK Building Regulations are always instinctively met as a result of proficient knowledge and understanding.

    Mezzanine Floors Demystified: Addressing Common Queries

    Not used
    Does A Mezzanine Floor Add Value?

    Making sense financially for those looking to increase usable space at a relatively low cost, a mezzanine floor enables you to achieve this quickly and effectively whilst adding value. When comparing two empty properties of the same dimensions yet Property A has a mezzanine whilst Property B doesn’t, although both are the same in terms of height space and footprint area property A offers more capacity therefore more value. This contributes towards a positive ROI and enhances the cost benefits as property A can offer more functionality within the same space dimensions.

    Is A Mezzanine Floor Rateable?

    Generally speaking, rates are measured on how much a property is worth and because the market value of a property increases after a mezzanine floor installation it’s possible for rates to increase too, however the degree of permanence is the deciding factor. Although a mezzanine is seen as a temporary structure its often in the interest of the landlord and subsequent tenants  to keep a structure that offers sustainability and long term value, rather than removing it at the end of a leasing contract. It’s probable, for example that an office mezzanine floor would become a permanent feature because it enhances the building’s offerings however its permanence could incur chargeable rates. Guidance on rates can vary from council to council so for clarity on whether a particular mezzanine floor would be rateable, your Chartered Surveyor can advise.

    Does A Mezzanine Floor Count As A Storey?

    Because a mezzanine floor is built within an existing building it cannot be classed as an extra storey of the property, however the mezzanine floor itself can be multi storey. This is known as a multi tier mezzanine floor and is a perfect way to gain maximum use of tall spaces. The first tier can multiplied by as many times as the buildings height will accommodate, providing a substantial amount of usable floor space in comparison to a single tier mezzanine and all within the same footprint area. The upper levels can be utilised in ways that will best support the business and can even accommodate multiple functions across the levels.

    How Much Does A Mezzanine Floor Cost?

    As a bespoke solution a mezzanine floor is priced mainly on its size and weight load bearing. Factors including fire rating, access features and accessories are also included in the cost so it’s difficult to state an accurate price before a site survey is carried out, however as a mezzanine floor manufacturer, WSL can immediately add value and save you money. We manage your project through every stage including design, manufacture and installation so middle man mark up cost is eliminated and those savings are passed directly to you.  If it’s a choice between relocating the business, extending the building or installing a mezzanine floor, the latter certainly has the upper hand especially when you consider the added savings WSL can offer.

    Is A Mezzanine Floor Sustainable

    When we say the mezzanine is a “semi-permanent” structure, you may question durability however there is no need for concern. Mezzanine floors are specifically designed to suit the intended space and use and as one of the UK’s leading mezzanine floor designers and manufacturers we can assure you of endurance and stability. Whether you require additional office space or storage areas, with the right design, which ensures a safe load bearing for its use, your mezzanine floor will provide a long term sustainable solution.

    Does A Mezzanine Require Fire Rating?

    In many cases yes, however there are some circumstances that exempt this requirement such as the mezzanine of less than 10m2 which is used for storage purposes only. A larger storage only mezzanine up to 20m2 will require smoke detectors and any mezzanine accessed by people regularly will require fire rating. This includes office, retail, warehouse, manufacturing and hospitality settings. Mezzanine fire rating barricades the structure itself protecting it from heat, smoke and flames for an extended period of time. This allows a time-delayed effect giving you a longer period of time to evacuate and have the fire distinguished before the flames reach the structure underneath. Fire rating entails:

    • Underside – Fissure tiles are fitted across the entire span of the underside delaying the time for fire and heat to reach the structural floor.
    • Columns – Moulded around the columns fire resistant castings work to protect the columns which hold the deck from extreme heat. These can be either galvanised or colour coded for visibility.
    • Edges – Coated fascia is placed around the edges including stairway and open loading areas.
    • Cavity Barriers – Where the space between the floor and ceiling is over 20m vertical cavity barriers are fitted within the mezzanine ceiling, concealing any pocket openings to prevent smoke seeping through.

    All of the above allow up to one hour of protection. Trying to understand the regulations and requirements around mezzanine floor fire safety can often seem very complicated. This is why WSL take care of all aspects of fire safety and building regulations on your behalf. We work closely with regulating bodies and officers so you don’t have too, before passing all approved safety documentation to you.

    Do Mezzanine Floors Require Regular Inspections?

    Under the Provision and Use of Work Equipment Regulations (Puwer 1998) the commercial mezzanine floor which is categorized as workplace equipment, must be appropriately constructed to meet its purpose with minimal risk to the health and safety of those expected to use it. Despite its robust steel framework, a mezzanine floor is still structurally vulnerable to knocks, bumps and general wear and tear which can cause progressive weakening. It could be that the handrail on the staircase has become loose, a fork lift truck collision has weakened the structure or the decking is becoming worn, affecting the surface. A professional, annual mezzanine floor inspection can help ensure the continual integrity of the structure with the early detection of weaknesses and risks. This enables appropriate action to be taken earlier rather than later, which can help to prevent a catastrophic event making your annual mezzanine floor inspections an effective way to ensuring your compliance with PUWER 1998.

    At WSL we offer professional mezzanine floor inspections for all types of mezzanine floor structures for which SEMA codes are followed. We can inspect your mezzanine floor structure after which you will receive a detailed report of any findings and paperwork to document that the inspection has taken place. For a quotation and availability, contact our inspections coordinator on 0113 2045350.

    Is A Small Mezzanine Floor Beneficial?

    It may be true that many of the mezzanine floor projects carried out by WSL are large scale, but it is also true that many are of a smaller size too. Mezzanine floors of any size are the perfect way to maximise limited spaces without compromising the ground floor area. A small mezzanine floor is certainly worthwhile if you just need that little bit of extra floor space to accommodate new or expanding working areas. By making a significant improvement to your workspace, a small mezzanine floor can bring huge value to your operation, and all you need is sufficient height space and the expertise of the WSL design team for this to be possible.

    In all types of settings, WSL has installed a small mezzanine floor for all kinds of purposes including additional storage, offices, veterinary treatment rooms and a dance studio. However you intend to use your raised platform, WSL will design and implement a bespoke solution to match your exact needs and on budget. Your project will be carried out with the same level of attentiveness as any other project, because at WSL we focus on your requirements individually to ensure we create a bespoke solution that will bring you long term savings in terms of time, money and space.

    You can even future proof your small mezzanine floor

    A small mezzanine floor with a future proof design will be much easier to extend should your needs change later down the line. Investing in additional floor space you don’t currently need makes no sense, however investing in floor space you do currently need with the assurance this can be extended easily and quickly in the future, makes perfect sense. This is a huge advantage should you anticipate future growth because it means that your immediate needs can be met and should you need that extra floor space in the future, it will be simple and easy to achieve.

    Mezzanine Floor Design


    The key element for a mezzanine floor design will be to understand the loads going onto it; how many people will be working on the floor, whether there will be any pallet racking or shelving and what Material Handling Equipment (MHE) will be used to move materials around. These will be the factors in calculating the standard deflection for the floor, impacting decisions on what the floor will be made of and whether the load needs to be dispersed with spreading plates on the floor below. Generally, office and retail mezzanines will need to have less deflection than is allowable in a standard loadings storage mezzanine floor.

    Building Regulations, Health & Safety


    Building regulations will dictate a number of issues, particularly the access routes. In order to comply with building regulations, designers and engineers will be considering the escape distance and types of access that are required. They will look at who is intended to be on the floor and how many people may require access at a time. The safety regulations for your mezzanine will be dependent on numerous factors, including the size of the mezzanine floor, its use, and intended users. You will need expert help to clarify the exact specifications that you need to follow for your project – more information can be found in our article “Mezzanine Floor Safety – What You Need To Know About The Law
