Building on the Commonage
Quedjinup falls within what the City of Busselton calls the Commonage, a broad band of rural residential land west of Dunsborough that has been progressively cut up from old grazing paddocks into two and three hectare lots. Anyone who has driven Caves Road will recognise the pattern, a horse paddock behind a timber fence one year, a cleared building site with a new driveway crossover the next. Recent subdivisions such as Lot 7 Caves Road, marketed as Summer Paddock, and the current proposal on Biddle Road follow the same script set out in the Commonage Consolidated Structure Plan, which sets the lot yield for the area at roughly one dwelling per two to three hectares depending on the property.
Most of this land was cleared decades ago for grazing, so the jarrah and marri forest that would naturally cover this part of the Ridge is largely gone, replaced by old windbreak plantings of tuart, blue gum and other non-local species along the fence lines. That history matters for design. A new home on a Quedjinup block is rarely working with remnant bush to build around, it is usually working with a cleared paddock, an existing shelterbelt, and a requirement to replant screening vegetation along the Caves Road frontage as a condition of subdivision. Soil across much of the area falls into the Cowaramup wet vales or deep sandy rises categories, and groundwater typically sits around two metres down, which shapes what an effluent disposal system can look like on a given lot long before it shapes what the house looks like.
Why Professional Architectural Design Matters
Coastal and regional projects come with constraints that aren’t always obvious at the start.
A structured architectural approach helps:
Address site-specific conditions early
Improve long-term durability and performance
Reduce costly design changes during construction
Ensure the home suits both lifestyle and environment
This leads to a more efficient build process and a better-performing final outcome.

Working within the Commonage and Ridge planning framework
A rural residential block in Quedjinup answers to more than the City of Busselton's Local Planning Scheme No. 21. It also sits within the area covered by State Planning Policy 6.1, the Leeuwin Naturaliste Ridge Statement of Planning Policy, which identifies Caves Road as a Travel Route Corridor. In practice this means new dwellings are expected to be screened from the road rather than announce themselves to passing traffic, and it is why recent structure plans in the area carry a 100 metre development setback from Caves Road backed by vegetation buffer planting, rather than leaving screening to individual owners' discretion.
Bushfire planning adds a second layer. Structure plans in the Commonage area have needed dwellings sited at least 27 metres from mapped extreme bushfire hazard vegetation to hold a BAL-29 rating, with construction to AS3959 and driveways upgraded to a standard fire trucks can use. Effluent disposal is its own puzzle given the shallow groundwater, sites are typically tested to two metres depth to confirm whether a conventional septic and leach drain system will work or whether a secondary treatment unit is required, particularly on the wetter Cowaramup soil types. We work through the applicable structure plan, the Ridge policy's screening requirements, and the bushfire and effluent studies as part of the initial site assessment, so a Quedjinup design is grounded in what the land will actually allow before a single elevation is drawn.
Our Design Philosophy
We believe architecture should be responsive, responsible and enduring. Our design process emphasises:
- Site-specific strategies that respond to coastal conditions, climate and orientation.
- A disciplined approach to form, structure and material that considers long-term performance.
- Collaborative and personalised engagement, ensuring your brief guides design decisions.
- A balance of innovation, practical delivery and contextual sensitivity.
This philosophy shapes work that is expressive yet grounded in practicality and place.

Over the years, we have created a range of built works across WA that demonstrate design sensitivity and contextual insight. Examples include:
About Quedjinup
Quedjinup is a semi rural locality within the City of Busselton, located directly west of Dunsborough with Caves Road forming its northern boundary. The name comes from the Wardandi dialect of the Noongar language and means place of women, and it was originally used to refer to the area now known as Dunsborough. Quedjinup had a recorded population of 420 at the 2021 census across an area of around 8 square kilometres, and it is home to Dunsborough Christian College. Much of the locality forms part of the City's Commonage precinct, a rural residential area of larger lots that continues to attract people who want space and privacy within a short drive of Dunsborough's shops, schools and coastline.
