Paving Adelaide landscaping a duplex front yard is more complicated than landscaping a typical standalone home. When two homes share one driveway, the frontage needs to work for both properties while still looking cohesive from the street.
The challenge is finding the right balance between vehicle access, pedestrian movement, privacy, planting and kerb appeal. Too much paving can leave the frontage looking hard and exposed, while oversized garden beds or poorly positioned plants can interfere with access and visibility.
For Adelaide properties, there is another consideration: the landscape needs to cope with the city’s seasonal conditions while making good use of limited front-yard space. The Adelaide Garden Guide for New Homes includes examples specifically involving shared front gardens and common driveways, including recommendations around soft landscaping, trees, permeable surfaces and privacy.
With careful planning, a shared driveway can become part of the landscape design rather than simply an unavoidable strip of concrete.
Start With the Shared Driveway
The driveway should be the starting point for the design, not something to landscape around afterwards.
Map the areas vehicles need to use, including entry, turning movements and access to garages or parking spaces. Then identify the areas that can safely accommodate planting.
This creates a practical distinction between traffic space and landscape space.
The Adelaide Garden Guide recommends coordinating front garden trees and services with driveway locations. It also identifies opportunities for garden beds alongside driveways and permeable paving that can support additional soil volume and planting.
For a duplex, this approach is particularly useful because the driveway is effectively a shared piece of infrastructure.
Avoid placing:
- Large shrubs where vehicles need to turn
- Low branches where they can obstruct vehicles
- Pots where they narrow access
- Dense plants around critical sightlines
- Garden edging that creates unnecessary hazards
The finished landscape should feel generous rather than squeezed around the driveway.
Create One Cohesive Front Garden
A shared driveway can easily make a duplex look like two unrelated houses.
Using a consistent landscape palette helps connect the two frontages.
For example, both homes could use the same:
- Garden edging
- Paving material
- Gravel
- Mulch
- Feature plant species
- Tree style
- Screening plants
The individual properties can still have their own entry areas, but repeated materials create visual continuity.
The Adelaide Garden Guide identifies a native formal garden character as particularly suitable for shared front gardens because it can provide a neat, relatively low-maintenance appearance when the space is viewed by multiple occupants or neighbours.
This is a useful design principle for duplexes: make the shared frontage look intentional rather than divided.
Separate the Two Entrances With Planting
Although the driveway may be shared, each dwelling should still have a clear sense of arrival.
Small planting zones can help define the individual entries without creating physical barriers.
For example, use a narrow garden bed beside each front path containing a small tree, grasses or low shrubs. The planting can visually separate the homes while maintaining the same overall design language.
Another option is to use repeated vertical elements.
Two matching feature trees—one associated visually with each dwelling—can create symmetry without requiring a large garden.
Keep Plants Low Near Vehicle Areas
Plant height matters around a shared driveway.
Low-growing planting is generally easier to manage near vehicle movement than large, spreading shrubs. Taller screening can be positioned further away from areas where drivers need a clear view.
The exact requirements depend on the property layout, driveway arrangement and relevant council or planning conditions, so avoid treating a generic plant height as a universal safety rule.
Use a Central Landscape Feature Carefully
A central feature can make a duplex frontage look more sophisticated, but it needs to be positioned outside the vehicle path.
Possible features include:
- A small ornamental tree
- A planted median
- A low garden bed
- Feature gravel
- A stone element
- Repeated native planting
For a narrow frontage, a central feature may not be practical. In that situation, placing landscape elements along the driveway edges can produce a similar effect.
The Adelaide Garden Guide shows shared-driveway designs where trees and soft landscaping are integrated alongside the common driveway rather than treating the driveway as a completely separate area.
Choose Trees Carefully
Trees can provide shade, privacy and greenery, but duplex front yards leave little room for mistakes.
Before choosing a tree, consider its mature height and canopy width, root characteristics, available soil volume and proximity to buildings, driveways and underground services.
The Adelaide Garden Guide specifically recommends selecting an appropriate tree species and size and positioning front-garden trees so they do not clash with overhead or underground services.
This is particularly relevant for duplexes because the available planting area can be fragmented by two entrances, a common driveway and service infrastructure.
Consider the Soil Volume
A tree needs more than a hole in a small patch of soil.
Where appropriate, permeable paving or porous surfaces can be used around landscape areas to help connect soil volume and improve water infiltration. The Adelaide Garden Guide specifically illustrates this approach around common driveways.
This can be useful when you want trees without sacrificing too much usable frontage.
Use Permeable Surfaces Where Appropriate
A shared driveway does not necessarily need to be one continuous sealed surface.
Depending on the project and engineering requirements, permeable paving, porous materials and gravel can be incorporated into appropriate areas of the landscape.
The Adelaide Garden Guide recommends maximising permeable or porous surfaces in relevant front-garden designs and demonstrates permeable driveway treatments alongside tree soil areas.
Potential applications include:
- Permeable pedestrian paths
- Gravel planting margins
- Porous driveway sections
- Permeable paving around garden beds
- Stepping-stone paths through planting
The choice needs to account for vehicle loads, drainage, accessibility and the property’s construction.
Create Privacy Without Blocking the Frontage
Privacy can be difficult in duplex developments because two households may have front windows, paths and outdoor areas facing the same street.
Instead of building a solid visual wall, use layered landscaping.
A combination of:
- Small trees
- Narrow shrubs
- Grasses
- Trellis planting
- Low hedges
can provide privacy while retaining openness.
The Adelaide Garden Guide specifically recommends using trees and plants to improve views and privacy in shared front-garden designs.
Planting should be positioned so it screens the areas that actually need privacy rather than blocking the entire frontage.
Make the Two Front Doors Easy to Find
A good duplex landscape should make navigation obvious.
Each property should have a clear pedestrian route from the street or driveway to its front door.
Use changes in:
- Paving
- Planting
- Garden edging
- Lighting
- Entry feature materials
to visually guide visitors.
You can use the same materials at both entrances while giving each dwelling a slightly different arrangement.
For example, both homes could have the same paving but different feature plants.
This maintains cohesion without making the two homes look identical.
Add Lighting to Improve the Frontage
Lighting can make a significant difference to a duplex front yard after dark.
Instead of flooding the entire driveway with bright lighting, use targeted illumination.
Consider lighting for:
- Front paths
- Entry doors
- Garden features
- Steps
- Driveway edges
- Feature trees
Keep lighting directed where it is needed and consider how it affects neighbouring properties.
For a shared driveway, consistent lighting on both sides can also help the frontage feel like one coordinated landscape.
Use Adelaide-Friendly Planting
Adelaide’s climate should influence the planting palette.
The city’s Mediterranean climate includes relatively wet winters and dry summers, so plants need to be selected according to the conditions of the particular property rather than appearance alone.
For a duplex frontage, consider plants that provide structure without requiring excessive space.
Depending on the site’s conditions, a landscape palette might combine:
- Compact native shrubs
- Native grasses
- Groundcovers
- Small feature trees
- Suitable flowering plants
- Low hedging
The South Australian Plant Selector+ can help match plants to local soil and landscape conditions, which is useful when selecting species for a specific site.
Do not assume every Australian native will automatically be suitable. Sun exposure, soil, drainage and mature size still matter.
Design for Two Households
A duplex front yard is shared visually, but ownership and maintenance arrangements can be more complicated.
Before installing landscaping, agree on practical questions such as:
- Who maintains the shared garden?
- Who pays for irrigation repairs?
- Who trims common screening?
- Which areas are private?
- Can residents place pots or furniture in shared areas?
- Who manages replacement plants?
These issues may be governed by the property’s title, development arrangements or agreements between owners, so landscaping decisions should not assume that every area can be treated as individually controlled.
For community-title developments, South Australian regulations now give councils powers concerning security for construction of common driveways in certain circumstances where the driveway has not been constructed before land division certification.
That is more relevant to development and title arrangements than ordinary garden maintenance, but it illustrates why shared-driveway projects should be considered as part of the property’s broader legal and planning framework.
Common Mistakes to Avoid
Treating the driveway as an afterthought
Design the driveway and landscaping together. Planting should fit around vehicle access rather than forcing drivers into awkward movements.
Making the two frontages completely different
Different landscaping styles can make a duplex look visually disconnected. Use shared materials and plant selections to create consistency.
Planting large trees too close to services
Check overhead and underground services before selecting and positioning trees. This is specifically highlighted in the Adelaide Garden Guide.
Blocking visibility with dense shrubs
Privacy planting should not compromise safe movement or visibility around the driveway.
Using too much hardscape
A large amount of concrete can leave a duplex frontage looking harsh. Where appropriate, incorporate soft landscaping and permeable surfaces.
Forgetting maintenance responsibilities
A beautiful shared garden can become a source of conflict if no one knows who is responsible for pruning, irrigation and replacement plants.
Frequently Asked Questions
How do you landscape a duplex with a shared driveway?
Start by mapping vehicle access and pedestrian routes. Then divide the remaining space into planting, privacy and entry zones. Use consistent materials and repeated plants to make the two properties look visually connected.
What plants work well beside a shared driveway?
Choose plants based on the available sunlight, soil, drainage and mature size. Low-growing plants are generally easier to manage close to vehicle areas, while taller screening plants can be positioned further from traffic paths.
Can you plant trees beside a shared driveway?
Potentially, yes. The tree must be appropriate for the available space, soil volume and surrounding infrastructure. Services, driveway access and mature canopy size should be considered before planting.
How can I make a duplex front yard look more private?
Use layered planting rather than relying on one solid screen. Small trees, narrow shrubs, grasses and trellis planting can provide privacy while retaining visual openness.
Should both sides of a duplex have the same landscaping?
They do not have to be identical, but repeating materials, plant species and design elements can make the overall frontage look more cohesive.
Can a shared driveway include landscaping?
Yes, landscaping can be incorporated alongside and, where suitable, around permeable driveway treatments. However, planting must not interfere with vehicle access, drainage, services or applicable requirements. The Adelaide Garden Guide includes specific shared-driveway landscape examples.
Final Thoughts
Landscaping a duplex front yard with a shared driveway is primarily an exercise in balance. The frontage needs to accommodate vehicles and pedestrians while still providing greenery, privacy and a welcoming entrance for both homes.
Start with the driveway layout, then identify where trees, garden beds, paths and screening can fit without creating conflicts. Use a consistent palette across both properties, select plants according to Adelaide’s conditions and consider permeable surfaces where appropriate.
For a new duplex or major front-yard renovation, it is worth developing the driveway, planting and drainage plan together rather than treating each element separately. South Australia’s Adelaide Garden Guide provides useful examples of how shared driveways, trees, soft landscaping, privacy and permeable surfaces can be coordinated in compact residential developments.
If the frontage has limited space or a complicated shared-access arrangement, a professional landscaping plan can help establish the layout before materials and plants are purchased.
