Patios Marmion
Marmion sits at the south-western corner of the City of Joondalup, directly on the coast opposite Marmion Marine Park. On most blocks here there is nothing between the backyard and the water, which makes a patio a materials decision before it is a design decision.
We build in Colorbond steel, powder-coated aluminium and insulated Solarspan panels. In Marmion we specify all three for the exposure rather than for an average inland backyard.

Why Marmion Homes Choose Us
- Coastal-grade Colorbond, powder-coated aluminium and corrosion-resistant fixings specified as standard on Marmion jobs.
- Used to Marmion's short streets, compact blocks and narrow side access.
- Building permits prepared and lodged with the City of Joondalup, which covers Marmion.
What a Front-Line Position Does to a Marmion Patio
Marmion is about as exposed as this coast gets. Salt-laden air arrives on the sea breeze most afternoons and settles on every surface it can reach, and the structures that age badly here are the ones specified as though they sat several suburbs inland.
Failure rarely starts with the roof sheeting. It starts at fasteners, at cut edges, and at any point where two different metals sit in direct contact, because that contact drives corrosion neither metal would suffer on its own.
None of that is an argument against a steel patio in Marmion. It means the coating grade and the fixing schedule belong in the quote, not in a decision made on the morning of the install.
| Detail | Common inland choice | How we handle it in Marmion |
|---|---|---|
| Roof sheeting | Standard Colorbond steel | Coastal-grade Colorbond, because the protective coating has to work harder this close to the water |
| Posts and beams | Standard-grade steel sections | Powder-coated aluminium where the design allows, since aluminium does not rust and the powder coat adds a second barrier |
| Screws and brackets | Standard plated fixings | Stainless or otherwise corrosion-resistant fixings, because fasteners streak with rust long before anything else does |
| Metal against metal | Different metals bolted straight together | Metals matched, or separated at the joint, so dissimilar metals are not left in contact |
| Cut edges | Cut on site and left as is | Cuts kept to a minimum, edges sealed, and the roof swept down before we leave |
Indicative guidance. The exact specification for your block is confirmed at the site measure.
The swarf nobody mentions
Drilling and cutting metal leaves fine steel filings across the roof sheet. Left sitting in Marmion air they rust where they land and stain the sheeting permanently, so the roof gets swept clean before the crew packs up.
Access and Upkeep on a Marmion Block
Marmion is a small suburb, known locally for its angling and aquatic club and the marine park offshore, with a short and quiet street network to match. Roof sheets, beams and posts still have to reach the backyard, and on plenty of homes here the only route is a side path between the house and the boundary fence.
We measure that access at the quote visit rather than on build day. If the path is too narrow, sheet lengths are chosen to suit the route in, or the material is lifted over the roof line, and either way it is priced from the start.
Rebuilt homes in Marmion often sit closer to their boundaries than the original houses beside them, which can leave very little side clearance. That changes how the frame is assembled and sometimes where the posts can land.
- Side access measured at quote stage, including gate widths, meter boxes and air conditioning units
- Sheet lengths chosen to suit the route into the backyard, not the other way around
- Unloading organised so a narrow Marmion street is not blocked longer than it needs to be
- Boundary lines and shared fencing checked before the frame is set out on a tight block
- Off-cuts, swarf and packaging taken away rather than left on site
Rinse it down
A hose over the roof, posts and gutters clears the salt film that builds up between rains. In Marmion this one habit adds years to the finish.
Reach the sheltered spots
Under the eaves, behind posts and inside beam channels never get rained on, so salt sits there undisturbed. Those are the areas worth aiming at.
Look along the fixings yearly
Rust streaks running down from screw heads are the early warning. Caught in time it is a fastener swap rather than a rebuild.
Keep gutters clear
Trapped debris holds damp salt against the metal, which is exactly where corrosion gets its start on a coastal block.
FAQs
Patios in Marmion FAQs
Yes. Marmion sits on the front line of the coast while Duncraig sits behind it, and that short distance changes how much salt reaches the structure. We treat coastal-grade Colorbond, powder-coated aluminium and corrosion-resistant fixings as standard on Marmion jobs rather than as an upgrade.
Almost always the fixings, the cut edges and any joint where two different metals touch. The roof sheeting usually outlasts all of them. That is why we spend more time on the fastener schedule and the detailing at joints than on the sheet itself.
There is no fixed rule, but a rinse every few weeks through the drier months does more for the structure than anything else you can do. Aim the hose at the sheltered areas as well, because the parts rain never reaches are the parts holding salt. It takes a few minutes.
Marmion falls inside the City of Joondalup, so the permit application goes to them. We prepare the drawings and the engineering certificate, lodge the building permit application with the council and deal with any questions that come back. You do not need to lodge anything yourself.
In most cases yes, but the access decides the method, so we want to see it before quoting. Options include cutting sheets to a length that can be carried through the side path, or lifting material over the roof line into the backyard. Both are workable, and both are costed up front rather than raised halfway through the build.
Yes. Marmion has original homes sitting alongside modern rebuilds, so there is no single look to match. On newer builds we usually run powder-coated aluminium posts and a Colorbond colour picked from the render and roof, and on original homes we match the existing fascia and roof colour instead.
