4 car garage sheds provide covered parking for four vehicles under one roof, with room left over for workshop space, storage, or equipment. Park four cars side by side, or use one or two bays for vehicles and dedicate the remaining space to storage, tools, or business operations without everything competing for the same area.
These structures use Australian BlueScope steel and site-specific engineering to handle the wide span across four bays. You choose the door configuration, internal layout, roof design, and features during the planning phase. Fair Dinkum Builds handles design, council documentation, and installation, delivering a garage that accommodates four vehicles plus whatever additional storage or workspace your property requires.

Why choose a 4 car garage shed
A 4 car garage shed suits properties where you need substantial vehicle storage or want vehicle parking combined with dedicated workspace. The four-bay layout provides ample space for multiple vehicles without requiring constant shuffling, and the remaining floor area supports workshop activities, business storage, or equipment that needs weather protection.
Four-bay structures work well for families with multiple vehicles, car enthusiasts with collections, or rural properties where you're storing a combination of cars, utes, tractors, and equipment. The available space means each vehicle gets its own bay, and you still have room for tools, spare parts, seasonal equipment, or materials that need to stay dry and secure.
The design also suits properties where you're running a business from home and need to separate work vehicles, inventory, and equipment from personal vehicles. Park commercial vehicles in dedicated bays, use another bay for materials or stock, and still have room for family cars. The extra space supports business operations without requiring multiple structures or off-site commercial premises.
Four-car garages require minimal maintenance once built. The steel construction handles harsh Australian weather conditions without deteriorating, and the enclosed design protects vehicles and equipment from sun damage, rain, and environmental exposure that would otherwise cause rust, fading, or degradation over time.

Choose your Four-door Garage Roof Pitch
5 degrees
5 degrees creates a distinctly modern and contemporary roofline. It's perfect for garage owners who take pride in aesthetics and want a sleek appearance. This pitch can only be used on skillion roofs.
11 degrees
11 degrees is often considered the ideal pitch for residential garages. It provides a classic, timeless gradient that's pleasing to the eye. You can use 11 degrees on either skillion or gable roofs.
15 degrees
15 degrees provides more expansive internal clearance for your garage. It creates a strong, defined roofline, and the roof slope performs well in harsh weather conditions. Suitable for both gable and skillion roof styles.
22 degrees
22 degrees is the perfect pitch if you want to fix solar panels onto your garage roof. It provides substantial clearance to house large cars easily. You can use 22 degrees on both skillion and gable roofs.
30 degrees
30 degrees suits garage owners who enjoy a robust architectural profile. The generous internal clearance area can hold a mezzanine or large vehicles. This pitch can only be used on gable roofs.
45 degrees
45 degrees creates a defined, impactful roof profile that resembles a church. It provides excellent performance in heavy rain or snowfall. Heritage-listed building owners often choose 45 degrees. Only suitable for gable roof garages.
Step skillion
Step skillion creates a distinctly current and modern garage aesthetic. Add extra shelter to your garage for storage or shade. Step skillions often provide ideal solutions for garages near height restrictions. You can combine roof pitch options suitable for skillion roofs (between 5 and 22 degrees).
Eave overhangs
Eave overhangs protect your garage openings from rainfall. They're favoured by those who want an ultra-modern looking garage and work effectively in both rainy and snowy climates.
Lean-to side walls
Lean-to side walls maximise available space by adding coverage to the side of your garage. They provide perfect areas for BBQs, additional storage, or workstations. Choose to enclose them with wall cladding or leave them open. Lean-tos are available on roof pitches ranging between 5 and 22 degrees and can be added to both skillion and gable roofs.
Choose your Four-door Garage Extras
InfinitiLine® gutter provides excellent water-carrying capacity and high-performance overflow protection in heavy rain events. The overflow protection slots are concealed to maintain a smooth, continuous line. This reduces the risk of water damage to your garage or its contents. Available in NSW and ACT only.
Other gutters let you create a rainwater solution suited to your garage and property. Various styles and sizes ensure compliance with regional requirements. The gutters we offer come in a wide variety of COLORBOND® steel colours. The large roof area on a four-bay garage collects substantial water during heavy rain, so proper gutter sizing is important.
Skylights introduce natural sunlight into your garage space. Choose from fibreglass or polycarbonate skylight sheeting to save on heating and lighting costs during the day. Our polycarbonate skylights are extra strong and made to last many years. They work well in large garages where natural light needs to reach interior areas.
Open or closed gables work with the high pitch of gable roofs to provide excellent water dispersion. Use them with eaves and other design options to make your garage stand out. Opt for open or closed gable design depending on your needs and preferences.
Insulation installs between the frame and sheeting across the roof and walls. Adding insulation becomes particularly valuable in large structures where temperature control affects comfort and usability. The extra space means more air volume, so insulation helps maintain comfortable conditions if you're spending time working inside. For more information on insulation performance, our guide to sheds with insulation explains how it affects different building sizes.
Windows and personal access doors add natural light and entry points without opening the main garage doors. Position windows along walls to bring daylight into workshop areas or storage sections. Personal access doors provide foot entry from different sides of the structure. Our guide to sheds with windows explains placement options.
Concrete slab provides the foundation for your four-bay garage. We coordinate slab preparation as part of the complete project, ensuring proper drainage, level surface, and adequate thickness to support vehicle weight across the full width.
Internal walls divide the interior into separate sections for different uses. Add walls between bays to create dedicated workshop space, secure storage areas, or separation between business and personal zones.
Mezzanine floors create upper-level storage above one or more bays without taking up floor space. This works particularly well in four-bay garages where you can dedicate some bays to ground-level parking and others to two-level storage. For detailed information, our page on sheds with mezzanine flooring covers design considerations.
Lean-to extensions add covered space along one side of the garage for additional storage, equipment, or outdoor workspace. The lean-to shares the main structure's framework, providing weather protection without the cost of fully enclosed space.

Common use cases for 4 Car Garage Sheds
Property owners choose 4 car garage sheds when they need substantial covered space for vehicles, equipment, or business operations under one roof.
Multi-vehicle households: Families with four or more vehicles use all bays for daily parking. Each vehicle gets dedicated space, eliminating the need to shuffle cars around for access. The protected parking keeps all vehicles out of weather and secure when not in use.
Car collectors and enthusiasts: People with vehicle collections use four-bay garages to store classic cars, project vehicles, or specialty automobiles. The ample space allows proper spacing between vehicles, room to work on projects, and storage area for parts and tools.
Rural property vehicle storage: Farm owners and rural properties store combinations of vehicles, tractors, ride-on mowers, and equipment. The four bays accommodate different sizes of machinery while providing room for tools, materials, and supplies that need weather protection.
Home-based business operations: People running businesses from home use 4 car garage sheds to separate work and personal vehicles. Park commercial vehicles or utes in dedicated bays, use other bays for inventory, materials, or workshop activities, and still have room for family cars. The serious storage capacity supports business operations without requiring separate commercial premises.
Workshop and vehicle storage combination: Tradies and contractors park work vehicles in two bays and convert the remaining space into dedicated workshop areas. The workshop space holds tools, equipment, and materials without interfering with vehicle access or storage.
Recreational vehicle storage: Property owners with multiple recreational vehicles use four-bay garages to store boats, caravans, jet skis, or camper trailers alongside daily vehicles. The extra space accommodates larger recreational equipment while keeping standard cars protected.
Mixed-use storage solutions: Some property owners use the four bays for completely different purposes—one or two for vehicles, one as a workshop, another as a general storage area for outdoor furniture, sporting equipment, or seasonal items. The fully customisable layout adapts to whatever combination of uses the property requires.
The versatility of 4 car garage sheds means they adapt to changing needs without requiring structural modifications. What starts as four-vehicle parking can evolve into workshop configurations, business space, or mixed-use storage as your requirements develop.
Common sizes for 4 Car Garage Sheds
Four-car garages come in dimensions that suit your property and what you're storing. Certain sizes are more common because they provide adequate width for four standard vehicles plus working room.
12m × 9m (four standard bays): This size gives you four 3-metre wide bays, suitable for parking four standard vehicles with comfortable room to open doors and walk between parked cars. The 9-metre depth accommodates most standard vehicles with space for front or rear storage.
12m × 12m (extended depth): The extra length provides room to park longer vehicles or creates storage space behind parked cars. This configuration works well if you're using one or more bays as workshop space or need to store equipment at the rear of the structure.
14m × 9m or 15m × 9m (wider bays): The increased width provides approximately 3.5 to 3.75 metres per bay, which suits larger vehicles, provides more comfortable working room, or creates space for shelving and storage along internal walls. This size accommodates utes, vans, or recreational vehicles that need wider clearance.
Custom dimensions: Your 4 car garage shed gets built to your exact specifications regardless of size. Your Fair Dinkum Builds representative will work through dimensions that suit what you're storing, your property boundaries, and any council restrictions. The structure is fully customisable to match your available space and requirements. For detailed information on sizing, our garage dimensions and sizes guide explains clearances and layout considerations.
