Complete Dual Occupancy Design Services From Site Feasibility To Planning Drawings & Working Documentation

Dual Occupancy Design Services Melbourne

Vaastu Atelier provides dual occupancy design services across Melbourne, helping landowners, families, investors and developers transform residential land into two well-planned, council-responsive and highly liveable homes.

A successful dual occupancy project is not only about placing two dwellings on one block. It must balance site potential, Clause 55 requirements, neighbourhood character, vehicle access, garage design, private open space, tree canopy, solar access, overlooking, overshadowing, stormwater, waste, landscape, subdivision and long-term property value.

Our dual occupancy design services cover the full project pathway, from early site feasibility and layout testing through to concept design, planning permit drawings, consultant coordination, working drawings and builder pricing documentation.

Whether your site suits a side-by-side dual occupancy, front-and-rear layout, one dwelling behind another, retained existing home with rear dwelling, corner block dual occupancy or luxury two-dwelling development, Vaastu can help assess the opportunity and shape the right design strategy.

01

Dual Occupancy Site Feasibility Review

Before designing two dwellings, the site should be reviewed carefully.

A block may look suitable for dual occupancy because of its land size, but the realistic outcome depends on frontage, depth, zoning, overlays, easements, trees, slope, drainage, vehicle access, neighbouring windows, private open space, tree canopy, stormwater, waste and market expectations.

A site feasibility review helps identify whether the land is best suited to side-by-side dual occupancy, front-and-rear dual occupancy, retain-and-build-behind, townhouses, a single luxury home or another residential strategy.

We Review

  • Property address
  • Land size
  • Street frontage
  • Site depth
  • Corner block potential
  • Orientation
  • Slope
  • Existing dwelling location
  • Neighbouring dwellings
  • Neighbouring windows
  • Street character
  • Zoning
  • Overlays
  • Easements
  • Trees and vegetation
  • Driveway access
  • Garage potential
  • Private open space potential
  • Tree canopy opportunity
  • Stormwater and drainage
  • Waste collection strategy
  • Subdivision potential
  • Planning permit pathway
  • Construction access
  • Market appeal
  • Long-term property value

Best For

  • Clients buying land
  • Owners with larger blocks
  • Clients comparing dual occupancy and townhouses
  • Developers testing site potential
  • Families considering redevelopment
  • Clients with corner blocks
  • Clients wanting to retain the existing house
  • Clients unsure whether two homes are realistic
  • Clients wanting early design advice before committing

Service Outcome

  • A clear early direction showing whether the site has realistic dual occupancy potential and what design pathway should be explored next.

02

Dual Occupancy Development Strategy

A dual occupancy project should begin with a strategy, not just a drawing.

The strategy should identify the best layout type, planning risk, market direction, access strategy, private open space approach, landscape response and likely documentation pathway.

Development Strategies May Include

  • Side-by-side dual occupancy
  • Front-and-rear dual occupancy
  • One behind another dual occupancy
  • Retain existing house and build behind
  • Corner block dual occupancy
  • Luxury dual occupancy
  • Contemporary dual occupancy
  • French Provincial dual occupancy
  • Knockdown rebuild dual occupancy
  • Subdivision-aware dual occupancy
  • Premium resale dual occupancy
  • Build one and sell one strategy
  • Build one and rent one strategy
  • Family land development strategy
  • Parents and children living arrangement
  • Downsize and retain land value strategy

We Help Clarify

  • Whether two dwellings are realistic
  • Whether side-by-side or front-and-rear layout is better
  • Whether the existing house should be retained
  • Whether a corner block can improve dwelling identity
  • Whether townhouses may be better than dual occupancy
  • Where garages and access should go
  • How private open space can be achieved
  • Where tree canopy and landscape should be allowed
  • Whether planning risk is manageable
  • What consultants may be required
  • What documentation pathway is required

Service Outcome

  • A project direction that gives the dual occupancy design process a clear foundation before concept design begins.

03

Dual Occupancy Yield & Layout Testing

Dual occupancy yield testing helps determine how two dwellings can realistically work on the site without compromising planning compliance, liveability or value.

The goal is not only to fit two homes. The goal is to create two good homes that are private, functional, marketable and capable of being approved and built.

Layout Testing May Explore

  • Side-by-side dwellings
  • Front-and-rear dwellings
  • One dwelling behind another
  • Retaining the front house
  • Replacing the existing house with two new homes
  • Corner block dual frontage layout
  • Attached dwellings
  • Semi-detached dwellings
  • Detached dwellings
  • Single-storey and double-storey options
  • Garage locations
  • Private open space options
  • Different dwelling sizes
  • Different resale or rental strategies

We Consider

  • Land size
  • Frontage width
  • Driveway length
  • Garage arrangement
  • Vehicle turning
  • Private open space
  • Solar access
  • Tree canopy
  • Waste storage
  • Overlooking
  • Overshadowing
  • Street presentation
  • Subdivision boundaries
  • Construction practicality
  • Market demand
  • Planning risk

Service Outcome

  • A realistic dual occupancy direction showing the layout type most suited to the site.

04

Clause 55 Design Strategy

Dual occupancy developments in Melbourne generally need to respond to Clause 55 because they involve two dwellings on one lot.

A dual occupancy design should be shaped around Clause 55 from the earliest concept stage, not adjusted later after the layout is already fixed.

Vaastu provides Clause 55-focused design services to help align the development with planning expectations.

Clause 55 Design Strategy Includes

  • Neighbourhood character response
  • Street setback review
  • Building height review
  • Side and rear setback planning
  • Walls on boundary strategy
  • Site coverage review
  • Access and crossover planning
  • Tree canopy planning
  • Front fence response
  • Parking location review
  • Street integration
  • Entry design
  • Private open space planning
  • Solar access to open space
  • Functional layout
  • Room depth
  • Daylight to new windows
  • Natural ventilation
  • Storage
  • Daylight to existing windows
  • Existing north-facing window review
  • Overshadowing review
  • Overlooking response
  • Internal views between dwellings
  • Permeability and stormwater coordination
  • Solar energy system consideration
  • Rooftop solar allowance
  • Waste and recycling strategy
  • Noise impact consideration

Service Outcome

  • A dual occupancy design strategy that considers the key planning standards early and reduces the risk of avoidable redesign later.

05

Side-by-Side Dual Occupancy Design Services

This layout can provide each dwelling with strong street presence, separate identity, independent entry and private rear open space.

Side-by-Side Design Services Include

  • Frontage suitability review
  • Dwelling width testing
  • Garage location planning
  • Entry separation
  • Façade balance

  • Owners wanting to retain a front home where possible

Service Outcome

  • A front-and-rear dual occupancy layout where both dwellings feel practical, private and liveable.

07

Retain Existing House + Build Behind Services

Some dual occupancy projects retain the existing front dwelling and add a second dwelling at the rear.

This can reduce demolition cost and allow staged development, but it only works when the existing home is well positioned and the rear of the site has sufficient development potential.

Retain-And-Build-Behind Services Include

  • Existing house position review
  • Existing house condition discussion
  • Side driveway suitability
  • Rear building envelope testing

  • Deep blocks
  • Owners wanting staged development
  • Owners wanting to keep the front home
  • Investment or rental strategies
  • Family accommodation at rear

Service Outcome

  • A practical strategy for adding a second dwelling while retaining the existing home where the site allows it.

08

Corner Block Dual Occupancy Design Services

Corner blocks can be excellent for dual occupancy because each dwelling may be able to address a different street.

This can reduce shared driveway issues and create two homes with stronger identity, better access and improved resale appeal.

Corner Block Design Services Include

  • Primary street frontage review
  • Secondary street frontage review
  • Front setback strategy

Different

What Makes Our Dual Occupancy Design Service Different?

1

Feasibility Before Design

We consider what the site can realistically support before committing to a layout.

2

Planning-Led Design

We consider Clause 55, setbacks, height, access, private open space, tree canopy, stormwater, overlooking, overshadowing and waste early.

3

Development Understanding

We understand the balance between two-home yield, approval pathway, construction cost and resale value.

4

Premium Residential Design

Our dual occupancy projects are designed to feel like quality homes, not basic rear-unit developments.

5

Multiple Layout Strategies

We can test side-by-side, front-and-rear, corner block and retain-existing options where relevant.

6

Consultant Coordination

We can coordinate with town planners, arborists, traffic consultants, civil engineers, WSUD consultants, landscape designers and other specialists.

7

Subdivision Awareness

We consider future title boundaries, access, services and common property from the beginning.

8

Documentation Quality

Strong documentation helps support planning, consultant coordination, builder pricing and construction clarity.

Can dual occupancy be subdivided?

Yes. Many dual occupancy developments are designed with future subdivision in mind, subject to council, servicing, access, drainage and title requirements.

What documents should I send before starting?

Please send the property address, title or Section 32, feature and level survey, existing plans if available, planning history, arborist information if available, preferred development type, budget range and project goals.

What makes a dual occupancy development successful?
