Dome Alfresco & Entertaining Patios in Perth
A dome roof alfresco does what a flat roof never will: the curved profile sheds rain fast, allows generous natural light at the edges, and gives the whole space a considered, architectural feel.

Why a dome profile suits alfresco entertaining
The dome's curve is not decorative. It creates a natural run-off angle that drains rain clear of the entertaining area even during Perth's heavy winter storms.
The elevated apex also improves airflow under the cover, keeping the space cooler in summer than a low flat roof at the same height.
Light where you want it
Because the dome rises toward the centre, you can run a clerestory translucent panel along the ridge without any rain ingress risk. The result is a bright, airy alfresco that does not feel like a covered room.
Planning your entertaining zone
Think about where the afternoon sun sits in summer. A correctly-oriented dome can shade the hottest corner of your alfresco while still letting morning light through the sides. We talk through orientation at every site visit.
Integrated features we build in from the start
- Fan and downlight mounting points built into the beam structure
- Downpipes routed internally through posts to keep fascias clean
- Optional infill walls, louvre panels, or cafe blinds for year-round use
- Flush connection to the existing roofline where the structure attaches to the house
Materials and finish options
Every dome patio we build uses Australian BlueScope steel for the structural frame and Colorbond for the roofing. We do not substitute imported steel or generic sheeting.
Choosing your Colorbond colour
Colorbond's 22 standard colours cover the full range from classic Monument and Surfmist through to earthy Jasper and Woodland Grey. We bring physical sample panels to every consult so you can see the colour in your actual light conditions.
The most popular choices for Perth alfresco areas are Monument, Surfmist, and Jasper, but your roof, render, and cladding tones should lead the decision.

Frequently asked questions
Yes. Any structure attached to a dwelling in WA requires a building permit. We prepare and lodge the application on your behalf as part of the service.
Most standard alfresco patio builds take a few days on site once the permit is approved. Council approval itself typically takes several weeks, and the exact timeframe depends on your local authority. We give you a realistic schedule at quote stage.
Yes. We attach directly to the existing wall structure using purpose-made flashing and brackets. The connection detail forms part of the engineer-certified drawings so it is weathertight and structurally sound.
We build everything from compact covers through to large entertaining zones. The maximum size is governed by your setback requirements and site coverage allowance, which we check against the relevant council's R-Codes during design.
Yes. We design the flashing and ridge connection to suit your existing roofing profile so the junction is weathertight and visually clean.
It can reduce direct light to adjoining rooms, which is why the dome profile matters. A translucent clerestory panel along the ridge, or polycarbonate infill at the edges, lets you keep the shade outdoors without darkening the rooms behind it.
The curved profile distributes wind load along the arc, which allows for efficient steel use without relying on heavy purlins. Combined with engineer certification, the structure is rated for your site's wind conditions.
Our guarantee covers defects in workmanship for the life of the structure. It sits alongside the manufacturer warranties on Colorbond steel and BlueScope framing, which we also pass through to you.
