— Size. Floor area drives the kit, slab and labour costs almost linearly.

— Concrete slab. An engineered slab is often 25–35% of the total — an existing slab saves thousands.

— Steel grade & wind rating. Cyclonic and high-wind regions need heavier engineering that raises the kit price.

— Doors & inclusions. Extra roller doors, windows, skylights, insulation and lining all add to the base kit.

— Approvals & site. Council or certifier approval, sloping sites and tight access add cost before the shed even arrives.

— Most sheds beyond a small garden size need building approval — factor the certifier's fee and lead time in.

— Get the slab and shed quoted together so no one can blame the other trade if something doesn't line up.

— Insulating the roof at build time is cheap; retrofitting it later is not.
