Shed Engineering Guides
Everything you need to know about shed engineering in Australia — from wind loads and slab design to permits, costs, bushfire ratings, and owner-builder requirements. Written by a chartered structural engineer with 20+ years experience.
Planning & Decision Making
Do I Need a Shed Engineer?
When engineering is legally required, what councils demand, and why kit shed drawings often aren't enough.
Costs & Pricing
What shed engineering costs, what's included, what drives the price, and how to avoid paying twice.
Building Permits
State-by-state permit requirements, exempt thresholds, documents needed, and step-by-step process.
Owner Builder Guide
State-by-state owner builder requirements, insurance, what you still need from an engineer, and common pitfalls.
Extensions & Modifications
Lean-tos, extensions, mezzanines, door additions — what's involved structurally and what permits are needed.
Technical Engineering
Wind Loads & Design
Wind regions, terrain categories, internal pressure, uplift — why wind is the critical design action for every shed.
Slab & Footing Design
Thickened edge slabs, pier footings, soil classification, point loads, and why the slab is as critical as the shed frame.
Materials & Framing
Portal frame vs C-section, hot-rolled vs cold-formed steel, purlins, girts, bracing, and connection types.
Why Sheds Fail
Wind uplift, connection failure, bracing collapse, foundation failure, and the construction shortcuts that cause them.
Cyclone-Rated Sheds
Wind regions B-D, cyclonic connection categories, tie-down requirements, and what makes cyclone-rated engineering different.
Sloping Site Sheds
Cut and fill, stepped footings, retaining walls, variable column heights, and drainage solutions for slopes.
Bushfire-Rated Sheds
BAL ratings, material requirements, ember protection, and AS 3959 compliance for sheds in bushfire-prone areas.
