Development Pathways
One Site. Three Possible Directions.
The right pathway depends on the land, the planning controls and what you want the project to achieve.
What must work
Frontage, access, parking, privacy and private open space need to be tested early against planning controls and the neighbouring context.
What it can create
Two independent homes with their own entries, outdoor areas and parking, coordinated through one project and delivery strategy.
Best suited to
Sites with enough usable land to separate the dwellings and establish distinct entries, outdoor areas and building relationships.
What must work
Driveway access, turning, parking, services, setbacks, landscaping, privacy and the relationship between front and rear areas all require careful testing.
What it can create
Two separate homes on one site, subject to the applicable planning and approval pathway.
Best suited to
Larger or appropriately located sites where a more involved residential outcome may be worth investigating.
What must work
Permissibility, density, access, parking, waste, services, landscaping, neighbouring impacts and project feasibility must be considered together.
What it can create
A selected small residential project such as terraces, townhouses or another suitable dwelling arrangement, where the site and planning controls support it.
Development and subdivision outcomes are not automatic and require site-specific professional assessment.
Site-led Design Study
See How the Decisions Connect.
The Site
We analyse the land, context and opportunities that drive the outcome.
Planning & Buildability
We test controls, access, servicing and feasibility to understand what may be achievable.
Design Response
We shape the built form, open space and privacy to suit the site and the client's goals.
Early Cost Alignment
We align scope, siteworks, material decisions and realistic cost parameters early, so decisions remain practical.
Proposed Outcome
We present a clear concept and pathway forward to help the client decide with greater confidence.

Common Questions
Duplex & Development FAQs.
Clear answers before you commit to a design or approval pathway.
Dual occupancies are permitted with consent in R2 zones across NSW and may also be permitted in other zones under the relevant local environmental plan. Whether a particular site can support a duplex still depends on planning controls, exclusions, lot characteristics, access, services and the approval pathway.
An attached dual occupancy contains two dwellings joined within one building form. A detached dual occupancy contains two separate dwelling buildings on the same lot. The suitable arrangement depends on the site, planning controls, access, privacy and usable open space.
Some eligible dual occupancy projects may use a complying development pathway when every relevant requirement is satisfied. Other projects require a development application. The pathway should be confirmed through a site-specific planning review before design work progresses too far.
Subdivision is not automatic. It depends on the applicable planning controls, development consent, minimum lot requirements, servicing and the subdivision pathway available for the site.
Important cost drivers include demolition, access, slope and excavation, soil conditions, retaining, drainage, services, design complexity, finishes, authority requirements and the approval pathway. Early builder input helps align the concept with a realistic scope.
Ideally, involve the builder during feasibility and early concept planning. Buildability, site access, services, structural decisions and cost implications can then inform the design before major documentation and approval costs are committed.
