Melbourne’s Steep Block Specialists
Melbourne’s northeast suburbs are renowned for their beautiful, undulating terrain. From Eltham to Diamond Creek, Templestowe to Warrandyte, many properties sit on challenging sloping blocks that other landscapers simply won’t tackle.
At John French Landscape Design, steep blocks are our specialty. With over 44 years of experience engineering solutions for Melbourne’s hilliest suburbs, we transform seemingly impossible terrain into stunning, functional outdoor living spaces.

Our Approach to Steep Blocks
Understanding Your Site
Every steep block is unique. We begin with a thorough assessment of your site’s:
- Gradient and aspect: Understanding how water flows and where sun falls
- Soil conditions: Identifying stable ground and potential problem areas
- Existing vegetation: Working with VPO requirements and preserving key trees
- Access constraints: Planning for construction logistics and material delivery
- Drainage patterns: Ensuring water management is integrated into the design
Engineering Excellence
Steep block landscaping requires more than aesthetic design—it demands engineering precision. Our solutions include:
- Retaining walls engineered to last: Designed to relevant Australian standards, with engineering certification where required
- Proper drainage systems: Subsurface drainage, ag-drains, and waterproofing to manage water pressure
- Stable terracing: Cut-and-fill earthworks properly compacted and retained
- Safe access: Steps, ramps, and pathways designed for long-term use

Retaining Wall Options
We build retaining walls using various materials, each suited to different situations:
Timber Sleeper Walls
- H4 and H5 treated pine or hardwood sleepers
- Ideal for heights up to 1.2m
- Natural aesthetic that weathers beautifully
- Cost-effective solution for many applications
Concrete Block Walls
- Rendered or stone-clad for various finishes
- Suitable for greater heights with engineering
- Can incorporate steps, seats, and planters
- Long-lasting and low maintenance
Natural Stone Walls
- Dry-stacked or mortared construction
- Premium aesthetic using local or imported stone
- Excellent for bushland settings
- Creates natural planting pockets
Gabion Walls
- Wire cages filled with stone
- Excellent drainage properties
- Contemporary industrial aesthetic
- Cost-effective for long runs

Managing Council Requirements
Steep block landscaping often involves navigating complex planning requirements. Our experience includes:
Building Permits
Retaining walls over 1 metre in height typically require building permits. We coordinate with structural engineers and building surveyors to ensure compliance. Learn more about steep block permits and council approvals.
Vegetation Protection Overlays (VPO)
Many of Melbourne’s hilly suburbs fall under VPO protection. We’re experienced in preparing applications that satisfy council requirements while achieving your design goals.
Site Coverage and Cut-and-Fill
Council regulations often limit the extent of earthworks. We design solutions that maximise usable space within these constraints.
The Transformation
A steep block, properly landscaped, offers advantages that flat sites simply can’t match:
- Dramatic views and vistas from elevated positions
- Natural separation between garden zones and living areas
- Interesting topography that creates visual interest
- Privacy from terraced planting and level changes
- Unique character that sets your property apart

Investment Considerations
Steep block landscaping is a significant investment, typically ranging from $50,000 to $300,000+ depending on:
- The extent of retaining walls required
- Site access and material handling costs
- Engineering and permit requirements
- Quality of materials and finishes
- Planting and irrigation scope
While the investment is substantial, a well-executed steep block landscape dramatically increases property value and creates outdoor living spaces that flat sites simply cannot achieve.
