How much ceiling height does a mezzanine need?

As a general guide, a shed needs somewhere around 4.5m or more of internal height for a mezzanine to leave workable clearance above and below. Lower buildings can still take a storage platform, but the space underneath becomes restricted.

Does a mezzanine require approval?

Adding a floor level usually needs building approval because it changes the floor area and the structural loads on the building. Requirements vary depending on the council area and whether the space is used for storage or occupied by people.

Can a mezzanine be added to an existing shed?

Retrofitting is common, though the existing slab and frame have to be assessed to confirm they can take the additional load. Where they can't, adding footings and columns is usually enough to make it work.

Mezzanines in Tweed Valley

Overview

Create Additional Usable Space

Most sheds have three or four metres of dead air above head height doing nothing at all. At Urbon Sheds, we design and install mezzanines in the Tweed Valley that turn that volume into a genuine second level. Warehouses gain pallet storage, workshops gain a parts store and an office, and a domestic shed gains somewhere to keep the things that only come out once a year. The platform is engineered to the load it needs to carry, with the access stair or ladder positioned to suit the way you move around the building. If the structure below needs strengthening, or the building itself is still at concept stage, our shed design service sorts it out. Call 0402 550 311.

Frequently Asked Questions

Where a Mezzanine Makes Sense

Adding a floor inside an existing building is usually cheaper than extending the footprint, provided a few things line up.

Enough height to work with. You need adequate headroom both above and below the platform for the space to be genuinely usable rather than a crawl area.
A load rating that matches the use. Storing pallets calls for a much stronger deck than an office or a light storage area.
Access that suits the traffic. A straight stair works for daily use, while a ladder may be enough for a mezzanine visited a few times a month.
Support that doesn't obstruct. Column positions are worked out around how you use the floor below, not just what's structurally simplest.
