## What affects Shed Installation cost

- **Shed size:** Size is one of the biggest drivers of cost shed installation. A small garden shed starts at $900 AUD, a medium storage shed is $1,800 AUD, and a large workshop shed is $4,200 AUD when the slab or base is already prepared.
- **Site access:** Tight access or no vehicle access can increase labour time and handling difficulty. In these cases, pricing uses a 1.2 multiplier compared with a prepared slab or base ready site.
- **Base or slab requirements:** If the shed area already has a prepared slab or base ready, standard rates apply. If the job needs a new concrete slab, pricing uses a 1.45 multiplier, which can noticeably lift the total garden shed supply and install cost.
- **Minimum job charge:** There is a minimum job charge of $900 AUD when the calculated amount falls below that level. This means smaller shed installation jobs still need to meet a base call-out and labour threshold.
