A garage with mezzanine floor doubles your storage capacity by adding a second level above the ground floor space. Park vehicles or use the lower level for workshop activities, while the mezzanine holds tools, equipment, seasonal items, or anything else that needs to stay organised and out of the way.

Fair Dinkum Builds constructs garages with mezzanine floors using Australian steel throughout, with engineered floor joists and bearers that meet load requirements for your specific needs. You decide the mezzanine size, access points, and how much floor area to dedicate to upper-level storage. We handle everything from design and engineering through to installation and handover, so you get a structure that maximises your available space without extending the building footprint.

Why add a Mezzanine Floor to your new garage build?

Adding a mezzanine floor when you're building a garage is sensible if you need extra storage but can't expand the building footprint. The mezzanine uses vertical space that would otherwise sit empty above parked vehicles or workshop areas, giving you usable floor area on two levels within the same structure.

The upper level keeps infrequently used items separated from daily activities below. Store seasonal equipment, archived paperwork, spare parts, or bulk materials on the mezzanine while keeping ground floor space clear for vehicles and regular work. You can access the mezzanine via stairs installed during construction, with the stair location placed to suit how you move through the space.

A mezzanine floor also creates different zones within one building. Some people use the upper level as office space for running a home-based business, with the ground floor dedicated to vehicles or light manufacturing. Others partition the mezzanine into separate storage areas, keeping different categories of equipment or materials organised without mixing everything together.

The cost-effective approach means you get substantially more storage without paying for a larger building footprint or constructing a separate shed. The mezzanine integrates into the structure during the build, with floor joists and bearers engineered to handle the weight of whatever you're storing.


Customise your Garage with Mezzanine Floor

Every garage with mezzanine floor we build starts with your requirements. You choose the profile, colours, door configuration, roof pitch, and extras that make the structure work for both ground level activities and upper-level storage.

Choose your Profile

Stramit® Corrugated provides economical, proven performance for roofing and wall coverage. This profile blends traditional methodology with current engineering advances, yielding lightweight construction that installs quickly. Across Australia's varied climates, corrugated maintains consistent reliability, particularly where demanding wind conditions require robust materials.

Stramit Monoclad® achieves equilibrium between drainage efficiency, wind load management, and attachment simplicity. The matching Monolap lap joint system facilitates seamless single-plane roof construction across extended runs. Pitch compatibility extends down to two-degree minimums.

Stramit K-Panel® delivers expansive coverage suited to compact garage footprints. Lower profile height translates to reduced flashing material needs (advantageous for budget-conscious projects), while conventional fixing methods accelerate installation timeframes.

Stramit Monopanel® generates sharp, modern facade lines. Extensive COLORBOND® steel colour availability provides design flexibility, though Queensland, Northern Territory, and Western Australia distribution excludes this profile.

Stramit® C-Clad 280 merges heritage aesthetics with contemporary concealed fastening. Minimal profile depth cuts flashing requirements, and the sheeting accepts both horizontal and vertical mounting orientations. Maintenance and installation processes remain straightforward.

Stramit SharpLine® produces commanding architectural statements through its bold visual signature. This specialist wall cladding utilises direct-fix attachment and enables creative expression for distinctive builds.

InfinitiLine® gutter manages substantial water volumes through sophisticated overflow control during heavy precipitation episodes. Invisible overflow apertures preserve uninterrupted visual flow whilst safeguarding structure and contents from moisture damage. NSW and ACT distribution exclusively.

Open or closed-in gables establish design options for gable roof assemblies. Elevated pitch secures efficient water elimination, whilst gable treatment (exposed or enclosed) integrates with eaves and additional elements shaping final garage character.

Skylights inject overhead natural illumination via fibreglass or polycarbonate panel systems. Daylight penetration diminishes artificial lighting expenditure and reliance. Our polycarbonate specification achieves exceptional durability through extended environmental exposure cycles.

Insulation reduces heat transfer through the roof and wall cladding, making both levels more comfortable if you're spending time inside. This matters particularly if you're using the mezzanine as office space or the ground floor as a workshop, where temperature control affects how usable the space is year-round.

Windows bring natural light into the ground floor, reducing reliance on artificial lighting during the day. You can position them based on where you need light most: near workbenches, storage areas, or vehicle parking zones. Our guide to sheds with windows explains how window placement affects both light quality and ventilation.

PA doors (personal access doors) give you entry to the garage without opening roller doors. This saves time if you're moving between the garage and house regularly, or accessing the mezzanine on foot rather than by vehicle.

Concrete slab provides a solid, level base for the entire structure. We can organise this as part of the complete project, so you don't need to coordinate a separate contractor. A properly prepared slab supports both vehicle weight and the vertical load from the mezzanine floor and whatever you're storing on it.

Gable roof option creates additional headroom at the centre of the building, which can be useful if you want maximum height for the mezzanine level. The gable design also adds visual interest to the structure.

Common use cases for Mezzanine Floor garages

People build garages with mezzanine floors for specific reasons, usually because they need substantially more storage within a limited building footprint.

Additional storage without expanding footprint: Property owners who can't extend their building size due to boundary setbacks or council regulations use the mezzanine to double their storage capacity within the approved dimensions. The upper level holds seasonal equipment, archived materials, or bulk supplies while keeping the ground floor clear for daily activities. This approach is particularly cost-effective compared to building a second structure.

Home-based business with office space: People running businesses from home use the ground floor for vehicles, materials, or light manufacturing, while the mezzanine functions as office space. The separation means you can manage paperwork and administrative tasks without mixing them with physical work or storage areas below. The elevated position also creates a quieter workspace away from ground-level activity.

Workshop with organised tool storage: Tradies and hobbyists use the mezzanine to store tools, parts, and equipment that aren't needed daily. The ground floor stays clear for active projects and vehicle access, while the upper level keeps everything organised and accessible without cluttering the workspace. Tools and materials stay separated by category or frequency of use.

Vehicle storage with parts inventory: Car enthusiasts or people running automotive businesses use the ground floor for vehicle work and the mezzanine for parts storage. The upper level holds spare parts, tyres, fluids, and accessories organised by type or vehicle, while the ground floor provides space to work on cars without having parts competing for the same area.

Rural property equipment storage: Farm owners use the ground floor for larger machinery like tractors or ride-on mowers, with the mezzanine storing smaller equipment, fencing materials, chemicals, or feed. The vertical separation keeps different types of supplies organised and protects items from ground-level dust or moisture.

The flexibility of a garage with mezzanine floor means you can adapt how you use both levels over time without modifying the structure. What starts as storage space can become office space, or vice versa, as your needs change.


Common sizes for Mezzanine Floor garages

Garage with mezzanine floor builds come in dimensions that suit your property and what you're storing. Certain size combinations are more common because they provide enough height for both levels while matching standard vehicle requirements.

9m × 6m with mezzanine: This size gives you a ground floor suitable for one or two vehicles, with enough vertical space for a mezzanine above. The mezzanine typically covers part of the building length, leaving the remaining area as full-height space. The floor area on the upper level depends on ceiling height requirements for both levels.

12m × 6m with mezzanine: The most common configuration. The ground floor accommodates two vehicles or a workshop area, while the mezzanine extends across most of the building length. The extra floor space on the upper level provides substantial additional storage without increasing the footprint. For a detailed breakdown of how these dimensions work, our garage dimensions and sizes guide explains clearances and layout options.

15m × 6m or larger with mezzanine: This suits properties needing maximum storage or commercial operations. The ground floor holds multiple vehicles or functions as a large workshop, while the wide span mezzanine creates extensive upper-level storage or office space. The increased building height accommodates comfortable ceiling clearance on both levels.

Custom dimensions: If standard sizes don't fit your property or requirements, we'll build to the exact dimensions you need. Your Fair Dinkum Builds representative will work through what makes sense based on what you're storing, mezzanine floor area requirements, property boundaries, and any council restrictions on building size or height. Planning the layout properly from the start means you get usable space on both levels that works for current needs and future changes.


Where we can build your garage with a Mezzanine Floor

Fair Dinkum Builds operates across Australia through local teams who understand regional requirements. This includes engineering for your area, navigating local council processes, and building to Australian Standards for structural safety and compliance.

We construct garages with mezzanine floors in metro and regional areas, on residential blocks and rural properties. The process remains consistent regardless of location: you work with a local representative who manages everything from initial design and planning through to final installation.

The mezzanine floor is engineered to comply with building regulations and Australian Standards for load-bearing capacity. Your local Fair Dinkum Builds team handles the structural calculations and ensures the design meets safety requirements, so you don't need to research specifications yourself.

Contact us with your property location and we'll connect you with the right team to progress your project.
