How to Build a Mezzanine Floor in a Shed

Plan Layout

Step 1. Determine the overall size (width & length) of mezzanine floor you need and use crayon to mark out the location of posts, stairs and overall footprint on the surface

Step 2. Determine the clearance height you need. ie. you may need to allow adequate height for your forklift to travel under the mezzanine floor.

Engineer

Step 3. Contact a local structural engineer to calculate the necessary size steel required based on the heaviest object you will store on the mezzanine. This is calculated based on a weight per m2 footprint. 250kg/m2 is a common weight capacity used for mezzanine floor engineering calculation.

Materials you need to purchase are:

  1. Steel or timber posts. Size specified by your local engineer.
