Can I install a Flat Attached Patio myself?
Yes. Our DIY kits are specifically designed for owner-builders and capable DIY customers.
Are Flat Attached Patios cheaper than Gable Patios?
Generally yes. Flat Attached Patios typically require fewer structural components, making them one of the most economical patio styles.
Is engineering included?
Engineer-certified documentation is available with qualifying patio projects.
What colours are available?
We offer the complete Colorbond® colour range for patio applications.
Do you deliver throughout WA?
Yes. We deliver patio kits throughout Perth and regional Western Australia.
Do I need approval for a small attached patio or verandah?
An attached patio or verandah usually needs approval in WA because it is fixed to your home and changes the building's footprint and roofline. Even modest attached structures are assessed for structural adequacy, wind resistance and how they connect to the existing dwelling. Some councils may treat very small structures differently, but this should always be confirmed rather than assumed. Speak with your local government or a registered building surveyor to find out what applies to your project.
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.
