Australia's Largest Backyard Workshop Shed – 16 Square Meters of Serious Storage
When standard sheds aren't cutting it anymore, this is where serious storage begins. At 3m x 5.38m with 2.3m height clearance, you're getting a legitimate workshop space that handles ride-on mowers, full tool collections, timber storage, and workshop equipment – all under one lockable roof.
The Size Advantage
16 square meters isn't just "big for a shed" – it's nearly the size of a single garage bay. The difference? You're not sacrificing your actual garage. Park your cars where they belong and use this dedicated space for everything that's been cluttering your property for years.
What Actually Fits (Real-World Capacity): ✓ Ride-on mower + push mower + full garden equipment ✓ Complete workshop setup: workbench, tool storage, timber racks ✓ 6-8 adult bikes (vertical or horizontal storage) ✓ Small business inventory or tradie equipment storage ✓ Seasonal items, camping gear, sporting equipment – with room to spare ✓ Or configure as dedicated workspace for woodworking, metalwork, hobbies
260cm Wide Double Doors Change Everything
Most sheds make you angle equipment through narrow openings. These 260cm doors (that's 2.6 meters) mean you drive your ride-on straight in. Load timber without tilting. Move workbenches without disassembly. It's the difference between functional and frustrating.
Built for Australian Conditions
Galvanised steel construction (0.25mm color panels, 0.6mm zinc steel frame) handles coastal salt air, tropical humidity, and harsh UV without degrading. The gable roof design channels water away efficiently – no pooling, no leaks. Four ventilation vents (23cm x 10cm each) create constant airflow preventing condensation, mould, and that musty shed smell even in humid climates.
Professional-Grade Features
- Lockable security: Protect thousands of dollars in tools and equipment
- 2.33m peak height: Walk around comfortably, store tall items, work standing
- Industrial grey finish: Professional appearance that won't date
- Weatherproof design: Rain, wind, UV – this shed handles it
- Ventilation system: Four large vents maintain air circulation year-round
Foundation Requirements
For 16m² of storage, foundation is critical:
- Concrete slab (highly recommended): 100-150mm thickness, properly leveled, $800-1,500 installed
- Reinforced paver base: Adequate if properly prepared with compacted base
- Anchoring essential: Must be secured to foundation (included hardware)
Skipping proper foundation on a shed this size is false economy – do it right the first time.
Perfect For:
- Serious DIY enthusiasts needing dedicated workshop space
- Tradie storage – secure on-site equipment and inventory
- Properties with multiple vehicles requiring dedicated equipment storage
- Large families with accumulated outdoor gear, bikes, sporting equipment
- Hobby workshops – woodworking, metalwork, restoration projects
- Small business owners needing weather-proof storage without warehouse costs
Compare Storage Costs:
Commercial storage (15m²): $200-300/month = $2,400-3,600/year This shed: One-time investment + you own the asset forever
Over 3 years: Storage unit = $7,200-10,800 | This shed = $1899.95
Care & Maintenance:
Annual inspection of door hinges, locks, and ventilation. Check anchor bolts quarterly. Remove debris from roof after storms. The galvanised steel requires minimal maintenance – designed for decades of Australian outdoor use.
