FREESTANDING FLAT PATIO FAQS

Can a Freestanding Flat Patio be installed anywhere?

In most cases yes, provided suitable footings can be installed and local requirements are met.

Is a Freestanding Flat Patio cheaper than a Gable Patio?

Generally yes. Flat roof patios typically require fewer structural components.

What roofing profile is most popular?

Corrugated and Spanplus 330 are currently among the most popular options.

Can I install a Freestanding Flat Patio myself?

Yes. Our DIY patio kits are designed for capable owner-builders.

Is engineering included?

Engineer-certified documentation is available with qualifying projects.

Do you deliver throughout WA?

Yes. We supply patio kits throughout Perth and regional Western Australia.

Does a freestanding patio need approval in WA?

Freestanding patios generally still require approval in Western Australia, even though they are not attached to the house. Because they have their own footings and roof, they are treated as a structure and are assessed against the Building Code, wind loading and your council's planning rules. The fact that a patio stands alone does not automatically exempt it from a building permit. Check the specific requirements for your block with your local government before ordering or installing.

Do I need a permit for a patio in WA?

Whether a patio needs a building permit or another approval depends on the project, property and current requirements applied by the relevant authority. Confirm the applicable pathway with the permit authority or a registered building surveyor before building.

Do you deliver patio kits across all of WA?

Yes, we deliver patio kits statewide from our Bellevue factory, covering Perth and regional WA. Because kits are engineered for your specific wind region, they suit metropolitan, coastal and remote locations alike. Delivery details and timing depend on your location, so let us know your address for specifics.

Do you offer an installation workshop or support?

Yes, we provide an installation workshop and technical support to help DIY builders assemble their kits with confidence. The workshop walks through the key steps and common questions before you start on site. You can also reach our team if something is unclear during your build.

Do I need a concrete slab before building?

You need a suitable base, which is usually a concrete slab or engineered footings depending on your design and ground conditions. The engineering specifies footing sizes and depths so the patio is properly anchored for your wind region. Get the base right and cured before you start erecting steel.

Are your patio kits engineer certified?

Yes, our patio kits come with structural engineering documentation showing the design meets the relevant Australian Standards for your site's wind region and terrain category. This documentation is typically needed when applying for a building permit and gives confidence the patio will perform in WA conditions. Certification is matched to your specific kit rather than a generic design.

Are there finance options for a patio?

Yes, finance options can make a patio more manageable by spreading the cost over time rather than paying upfront. Our patio finance page outlines how this works so you can plan your budget. Approval and terms depend on the provider, so review the details before committing.

What Colorbond colours are available for patios and sheds?

Colorbond is available in a wide palette of colours ranging from light neutrals through to deep charcoals and classic heritage tones. This lets you match the roof, gutters and fascia of an existing WA home or create a contrasting feature. The easiest way to compare options is to preview shades on a render before deciding.
