To make the process either and to make sure your shed mezzanine is everything that you hoped for, there are some things you need to think about.

Please note: The above figures are general guides only. Be sure to consult an expert before you build your mezzanine.

What Is Going Underneath Your Flooring?

Will it have offices? Or will you need some extra space? Answering these questions will determine where and how many poles will be used to support the floor.

What Size Do You Want It To Be?

This stage is when you start brainstorming a floor plan. Consider the shape, width, length, and height of your mezzanine floor.

Consider what you will need to use it for, and what space is required to suit your needs.

What Handrails Will Be Needed?

How We Build A Mezzanine Floor In A New Shed Design

If a client has requested a mezzanine in their new building, we will include it in the structure of the shed. It is often the cheaper and easier solution to include the flooring in the initial designs, rather than getting it retrofitted at a later date.

Firstly, we go through the above questions to determine what is needed in the mezzanine floor and shed design. We will work with our client to find out the best solution to their requirements.

We will then prepare a detailed proposal, clearly detailing what you will receive. Every structure we build is thoroughly inspected and gets an engineering certificate. (Which also helps for council approval).

When you are happy with your designs (which also include a 3D concept of your shed and mezzanine floor), we then start the shed’s construction.

When we start building the shed frame, we will include brackets for the mezzanine flooring in the construction of our upright beams.

The mezzanine floor will be built during the construction phase of your shed. When your shed is fully complete, your mezzanine floor will be included, ready for use straight away.

Thinking About Building A Mezzanine Floor?

A mezzanine floor can be a great addition when building a new warehouse, factory or farm shed. It is essential you have a clear understanding of what you want, and what is needed to have your requirements fulfilled.

Whether you choose to do it yourself or consult an expert, it is vital that your structure is built correctly, and built to last.
