A mezzanine adds floor area without adding footprint. The design depends on what it carries and whether it shares columns with the building.
| Uso | Typical floor load |
|---|---|
| Offices | 3 kN/m² |
| Light storage, picking | 5 kN/m² |
| Heavy storage, pallets | 7.5–10 kN/m² |
| Plant and equipment | By equipment |
Typical design values; your code governs.
A free-standing mezzanine has its own columns and bracing and can be moved. A tied mezzanine uses the building columns, which saves steel but must be designed with the main frame.
Plan it now: even a phase-2 mezzanine should be declared so main columns and foundations are sized for it.
