How much space do you need for a mezzanine?
Good question. Due to the nature of a mezzanine floor, you need to make sure you have enough height in the room. To build a mezzanine in an existing room you’ll want to make sure you have a minimum ceiling height of over 4m.
We would always recommend having a mezzanine specialist carry out an assessment of the room, to make sure the dimensions of the space are sufficient for adding a mezzanine.
