If needed, engineering is priced on its own in every region. Your final price also depends on colour, roofing and site needs. The weekly figure is a 36-month example.

LEARN ABOUT THE FREE WORKSHOPCAN YOU BUILD A PATIO YOURSELF?
Absolutely. Our DIY patio kits are designed for owner-builders — components arrive pre-cut and pre-punched, with step-by-step installation instructions. Engineering drawings are separate and can be arranged as an optional extra if required. With basic tools, a helper or two, and a bit of preparation, building your own patio is a rewarding project that saves you money. The key is taking your time on the early stages: accurate setting-out and properly poured footings make everything that follows far easier.

STEP-BY-STEP BUILD PROCESS
Follow these stages in order — always referring to your installation instructions and any engineering drawings arranged for your project.
- 1
Plan, Approve & Set Out The Site
First, check if you need a building permit. Mark the patio area with string lines. Mark each post from your plan. Measure corner to corner to check it is square.
- 2
Dig & Pour The Footings
Use the footing size and depth in your engineering drawings. If you have no drawings, get the right project details before you start. Brace each post straight. Pour the concrete and let it set.
- 3
Stand & Plumb The Posts
Place the posts over the footings or brackets. Make them straight in both directions. Brace them well. Check the heights and roof fall.
- 4
Fix The Beams & Attach To The House
Bolt the beams to the posts as shown in your plans. For an attached patio, fix the back beam to the home as shown. Keep it level. Add flashing to keep water out.
- 5
Install The Rafters & Battens
Fit the rafters at the spacing shown on your plan. Keep the frame square. Add the battens or top hats that hold the roof sheets. Check the roof fall again.
- 6
Lay The Roof Sheeting
Lay the roof sheets as shown on your plan. Use the right screws and overlap. Add flashing at the house. Fit the edge caps to keep water out.
- 7
Add Gutters, Downpipes & Finish
Fit the gutter and downpipes. Add any infill and trims. Clean the site. Check all work against your drawings before use.
SAFETY FIRST
Steel building work has real risks. Keep these in mind throughout your build.
COMMON DIY MISTAKES
Building your own patio or shed can save thousands of dollars, but there are some common mistakes that can make the project harder than it needs to be.
Not Checking Measurements Properly
Incorrect measurements can lead to ordering the wrong size structure. Always double-check your measurements before ordering.
Ignoring Council Requirements
Some patios and sheds may require approvals before construction begins. Failing to check this can cause delays and extra costs.
Building Footings Incorrectly
Footings are one of the most important parts of the structure. Footings that are too small, too shallow or incorrectly positioned can cause problems later.
Not Reading The Plans First
Many DIY builders rush straight into construction. Taking time to read the drawings and instructions before starting can prevent mistakes.
Not Checking Levels And Square
If posts, footings or frames are not level and square, the rest of the build can become much more difficult.
Tightening Everything Too Early
It is often easier to leave bolts slightly loose until the frame is fully assembled and aligned. Final tightening should happen once everything is in the correct position.
Working Without Enough Help
Large beams, roof sheets and structural components can be heavy and difficult to handle alone. Having extra help can make installation safer and easier.
Forgetting About Drainage
Good water drainage is important. Make sure gutters, downpipes and surrounding ground levels allow water to flow away from the structure.
Choosing Price Over Quality
Not all patio and shed kits are the same. Strong engineering, quality steel and correct components can make a big difference to the life of the structure.
Not Asking Questions
If you're unsure about something, ask. A quick phone call can often prevent hours of extra work.
BUILD WITH CONFIDENCE
Thousands of Australians successfully build their own patios and sheds every year. With the right planning, quality engineering and a little patience, a DIY project can be both rewarding and cost-effective.
