When to choose a freestanding structure
Attaching a patio to the house is the most common approach, but there are situations where a freestanding structure is clearly the better choice.
Distance from the house
If your entertaining area or pool zone is set well away from the house, running a roof back to the wall line becomes impractical. A freestanding patio sits exactly where you need it.
Heritage or listed homes
Some heritage-listed or character properties in Perth have restrictions on attaching new structures to the original walls. A freestanding patio avoids that problem entirely.
Maximising garden space
A freestanding dome patio positioned centrally in a large backyard creates a destination space rather than simply extending the house footprint.
Setback and coverage rules
Freestanding patios are subject to the same R-Code setback and lot coverage rules as attached structures. We check these against your property details during design so there are no surprises at the permit stage.
Structural features of a freestanding dome patio
Because the structure does not borrow support from the house walls, the four posts and the beam-and-rafter system carry all loads independently. We engineer accordingly.
- Four structural BlueScope steel posts set in engineer-specified footings
- Full perimeter gutter with internal downpipes through the posts
- Dome curve spanning the full width between the beams
- Optional infill panels, louvre screens, or café blinds
- Fan and downlight mounting points in the beam structure
A freestanding dome patio can sit anywhere on the property. The curve gives it a presence that reads as architecture, not just a cover.

Frequently asked questions
Yes, in most cases. Freestanding patios above certain dimensions require a building permit in WA. The thresholds vary by council, but we check and advise at the consult. We lodge and manage the permit on your behalf.
Footing depth and specification are determined by the structural engineer based on the span, post load, and soil conditions at your site. We arrange the footing inspection as part of the build process.
Yes. If you plan to add walls or screens later, we can design the initial structure with that in mind - stronger posts, additional connection points, and clearances for roller blinds or louvre panels.
A standard freestanding structure usually goes up within a few days on site once the permit is issued. The permit approval is the longer part of the timeline and depends on your council. We give you a realistic schedule with your quote.
We do not quote in general terms, as every build is priced to the specific design, size, and site conditions. A free quote gives you the actual number for your project.
Almost anywhere that meets your setback and site coverage rules, which is one of the main advantages over an attached structure. We check the boundary clearances and any easements at the site measure before finalising the position.
Often yes, provided the existing slab or footings can carry the post loads. The engineer assesses this during design. Where the existing base is not suitable, we include new footings in the scope.
Yes. We set the post heights and footing design to suit the fall of the land so the roofline stays true and the structure drains correctly. Sloping and split-level sites are common and handled at design stage.
