Steel garages for cars, caravans and boats
BWG Sheds designs and supplies steel garages for houses and acreage: single and double garages, extra-height bays for a caravan or boat, and garage-workshop combinations. Each garage is sized to the vehicles and the clearances you need, engineered for the site, and supplied as a kit or supplied and installed.

What people use garages for
Measure what you're parking, then add the room to open doors, walk around and store things. That, not a catalogue size, sets the garage.
- Cars and 4WDs
- Width for doors to open, length for a bench or storage at the back.
- Caravans and boats
- Extra-height bays with the door opening sized to the van or the boat on its trailer.
- Garage plus workshop
- A parking bay beside a workshop bay, with power, light and a personal access door.
Things to get right
Minimum parking sizes
The Queensland Housing Code's Table 5 sets minimum internal garage spaces of 3 m wide by 6 m deep for a single (3.2 m wide where level-entry access runs through the garage) and 5.5 m by 6 m for a double. Those are minimums, not comfortable sizes.
Design vehicles
The B99 design car in AS/NZS 2890.1 is 5.20 m long and 1.94 m wide; a B85 car is 4.91 m by 1.87 m. Utes and large 4WDs are longer than both.
Caravan height
Caravans can legally be up to 2.5 m wide and 4.3 m high, so measure your van (including the air conditioner) before choosing the door and eave height.
Approval for garages
In Queensland a shed avoids building approval only if it is 10 m² or less in plan area, no more than 2.4 m high (mean 2.1 m) with no side over 5 m, and not in Wind Region C. A garage almost always needs building approval, and a garage close to a boundary has to meet the siting rules or go to council for a referral. Requirements depend on your property, proposed structure and local planning/building controls.

Set out your garage yourself: gable or skillion roof, width, length, height, roof pitch and number of bays, then add lean-tos, doors and windows, cladding and colours, and turn it around in 3D as you go. Send us the design with the designer's Get Quote button and BWG Sheds will come back with a detailed price and a timeframe for that exact shed.

Garages: common questions
What size garage do I need for two cars?
The Queensland Housing Code minimum for a double garage is 5.5 m wide by 6 m deep internally, but that is a minimum. Allow more width if you want to open doors fully and walk between the cars, and more depth for a bench or storage.
How high does a caravan garage need to be?
Measure the van at its highest point, including the air conditioner and any aerials, then add clearance for the door mechanism. Caravans can legally be up to 4.3 m high, so a standard garage door height is often not enough.
Can I get a garage kit delivered?
Yes. Garage kits are delivered to sites in our Queensland service areas, with assembly plans and phone support.
Keep planning
- Garage kitsWhat's in the kit and what you organise
- DIY steel shed and garage kitsA kit makes sense when you're handy, you have help and equipment, or you already have a builder.
- Council and building approval assistanceApprovals are where shed projects stall: a missing site plan, a shed inside the boundary clearance, a flood overlay nobody checked.
- Supply and installSupply and install suits most farm sheds, larger garages, workshops and commercial buildings, and anyone who wants one party responsible for the build..
- What size shed do I need?
- Do I need council approval for a shed in Queensland?
- Shed kit, supply-and-install or custom design: which suits you?
