Dual Occupancy Landscape Documentation NSW
Consultant‑led landscape documentation for dual occupancy developments across NSW. Clear, coordinated plans supporting development application approval, shared interfaces, setbacks and access.
Dual occupancy developments introduce a level of spatial, regulatory and coordination complexity that is often underestimated. While typically smaller in scale than multi-unit projects, they still require clear, development-grade landscape documentation to support development applications and consultant coordination, particularly where access, setbacks and shared spaces must be clearly resolve.
Without clear landscape documentation, these projects can encounter approval delays or coordination conflicts between consultants early in the assessment process.
PARC provides dual occupancy landscape documentation as part of a broader residential development consultancy service, supporting architects, planners, project managers and boutique developers who require clarity, consistency and reduced interface risk across the design team.
This service focuses on landscape documentation prepared for approval, coordination and construction delivery, rather than lifestyle-led or decorative residential outcomes.
What we mean by dual occupancy
In this context, dual occupancy refers to residential developments comprising two self-contained dwellings on a single lot, commonly described as dual occupancy or duplex developments.
In practice, we are also engaged on closely related small-scale residential formats, including dual-key or dual-lock arrangements, where landscape documentation requirements are typically equivalent in terms of access, shared interfaces, setbacks and private open space coordination.
While terminology and planning definitions can vary across councils and development models, these projects consistently require clear, coordinated landscape documentation to resolve shared access, setbacks, private open space and dwelling interfaces, which this service is designed to address.
Dual occupancy as a documentation challenge
Dual occupancy and duplex developments sit at an intersection of competing requirements. Shared access arrangements, adjoining dwellings, private open space compliance and service coordination all need to be resolved within a constrained envelope.
This often becomes critical when:
-
shared driveways create ambiguity between dwellings
-
private open space compliance becomes unclear
-
planners request clearer definition of landscape responsibilities
Landscape documentation plays a key role by:
-
Clarifying spatial responsibility between dwellings
-
Resolving shared and transitional interfaces
-
Supporting coordination between architectural, civil and planning inputs
-
Reducing ambiguity that can lead to approval delays or downstream changes
Our approach treats dual occupancy landscape documentation as a development coordination problem, not a scaled‑down residential design exercise.
Scope of dual occupancy landscape documentation
Site structure and spatial definition
-
Interpretation of setbacks and landscape interfaces
-
Clear delineation between private and shared spaces
-
Resolution of edge conditions to adjoining properties and public interfaces
Access and shared interfaces
-
Driveway and accessway landscape coordination
-
Pedestrian circulation and entry sequencing
-
Integration of shared services, bins and utility zones
Private open space and amenity coordination
-
Definition of private open space extents
-
Coordination with building footprints and finished levels
-
Alignment with amenity, overshadowing and overlooking considerations
Planting documentation and specification
-
Planting plans prepared to support assessment and construction documentation
-
Plant schedules and specifications aligned with approval documentation
-
Coordination with site constraints and ongoing maintenance considerations
Consultant coordination
-
Alignment with architectural drawings and levels
-
Integration with civil layouts and drainage strategies
-
Documentation consistency across the consultant team
Landscape documentation within the dual occupancy development application
For dual occupancy developments, landscape documentation is prepared as part of the development application package and assessed alongside architectural, planning and civil documentation.
Councils rely on landscape plans to assess matters such as access arrangements, setbacks, private open space provision, site coverage and the resolution of shared interfaces between dwellings. This becomes particularly important where sites are affected by additional constraints such as heritage listings or heritage conservation areas, bushfire-prone land, flood affectation or estate design guidelines.
Clear, coordinated landscape documentation helps ensure these matters are understood consistently across the assessment process and aligned across the consultant team.
Who this service is for
This service is typically engaged by:
-
Architects delivering dual occupancy residential projects
-
Planning consultants managing development applications
-
Boutique developers coordinating small-scale residential developments
-
Project managers seeking clarity and reduced coordination risk
It is suited to projects where landscape input needs to be reliable, coordinated and proportionate to the development context.
Why coordinated landscape documentation matters
In dual occupancy developments, unclear or under-resolved landscape documentation can lead to:
-
Conflicting interpretations of shared space
-
Late design changes to address access or setback issues
-
Increased coordination effort during assessment or construction
Clear, well-aligned landscape documentation supports smoother approvals and reduces downstream risk across the consultant team.
Service area — New South Wales
This service is delivered across New South Wales, supporting dual occupancy developments in metropolitan, regional and coastal contexts where infill housing and small‑scale redevelopment are actively occurring.
Dual occupancy landscape documentation is most commonly required in:
-
Established residential areas zoned for low‑density housing, where infill development is subject to detailed assessment
-
Locations near public transport, local centres and community facilities, where low‑rise housing is encouraged but site constraints are heightened
-
Heritage‑affected residential areas, including heritage listings and conservation areas, where landscape outcomes form part of character and streetscape assessment
-
Residential land affected by environmental or planning constraints such as bushfire‑prone land, flood affectation or estate design guidelines
Engagement is guided by regulatory context, site constraints and approval complexity, rather than postcode alone.
