#1 Perth Landscaper
If you are treating your outdoor space as an afterthought, you are missing out on one of the most valuable aspects of your Perth, Western Australian property. In Perth, a backyard isn’t just a patch of grass—it’s an extension of your living room, an entertainment hub, and a critical defense against the scorching summer heat.
Yet, many homeowners across the metropolitan area find themselves trapped in a cycle of frustration. They battle the brutal, bone-dry January heat waves, struggle with highly hydrophobic (water-repellent) coastal sands, and watch expensive, generic store-bought plants wither by mid-summer.
At AllState Landscaping, we don’t believe in cookie-cutter garden makeovers that look great for a week and perish under the WA sun. Led by senior landscape architects, we build highly resilient, structurally sound, and stunning outdoor environments engineered specifically to thrive in Perth’s distinct climate. Whether you need a structural overhaul or a complete alfresco transformation, we handle everything from initial council-compliant drafting to final construction handover.
Tailored Landscaping Services in Perth
1. Structural Hardscaping & Retaining Walls
Perth’s undulating topography—from the limestone ridges of the coastal strip to the stubborn ironstone of the Perth Hills—demands precise structural engineering. We design and construct engineered retaining walls utilizing premium local limestone, engineered concrete sleepers, and Corten steel accents. Every wall is built to master soil retention, manage steep site gradients, and create flat, usable terraced zones for your home.
2. Custom Alfresco Living & Warping-Resistant Decking
The true Western Australian lifestyle happens outdoors. We design and install luxury timber and high-performance composite decking engineered to resist fading, splitting, and warping under extreme UV exposure. From custom-framed pergolas to complete outdoor kitchens featuring integrated stone masonry, we bridge the gap between your indoor living spaces and your backyard.
3. Precision Paving & Permeable Hardscapes
Whether it is a heavy-duty driveway in Subiaco or a poolside entertainment area in South Perth, our paving is laid over deeply compacted, engineered sub-bases. This meticulous preparation prevents shifting, sinking, and cracking during shifting ground conditions. We specialize in large-format natural stone, local liquid limestone, and permeable paving systems that optimize stormwater runoff.
4. Smart, Waterwise Irrigation & Sub-Surface Drainage
Water is our most precious resource in WA. We install fully automated, Water Corporation-compliant smart irrigation systems equipped with sub-surface drip lines and climate-responsive rain sensors. This setup ensures absolute maximum water efficiency while complying with local two-day-a-week watering restrictions. Additionally, we integrate sub-surface drainage systems to prevent winter waterlogging in heavy clay pockets like parts of Victoria Park.
5. Advanced Soil Reclamation & Softscaping
You cannot grow a premium garden in raw, unamended Perth sand. Our softscaping process begins below the surface. We actively transform hydrophobic, nutrient-stripped sand by deeply incorporating organic compost, bentonite clay, and active soil-wetting agents. Once your soil structure is rich and sponge-like, we layer it with custom-selected, drought-tolerant Australian natives (such as Westringia, Lomandra, and structural Kangaroo Paws) alongside hardy Mediterranean species that flourish beautifully with minimal water.
The Structural Gap: Why Competitors Fail (And How We Protect You)
When you look at a standard landscaping company in Perth, you’ll typically see galleries of beautiful, freshly finished projects. What they don’t show you is how those yards look eighteen months later.
As experienced landscape architects, we fill the critical execution gaps that general contractors routinely ignore:
- We Overcome Hydrophobic Soils: Most contractors simply throw down a layer of cheap topsoil and mulch. We chemically and physically alter the existing sandy substrate, blending kaolin or bentonite clay down into the top 300mm of soil to permanently fix water retention.
- Microclimate Architecture: A coastal property in Cottesloe faces brutal salt winds and glare, requiring highly durable, wind-resistant species. A property in South Guildford requires deep shade management and frost protection. We custom-engineer your planting palette based on your precise neighborhood microclimate.
- Total Compliance & Structural Insurances: In Western Australia, any residential landscaping work exceeding $7,500 requires a formal, legally binding written contract. We take complete ownership of the structural red tape—managing all local council building approvals, engineering sign-offs for retaining structures over 500mm, and site setback regulations.
Fixed-Price Transparency Built for Perth, Western Australia
We operate on a model of absolute clarity. There are no surprise variations or unexpected item costs halfway through excavation. We supply fully line-itemed, comprehensive quotes mapped clearly in Australian Dollars (AUD$) covering every phase of your project.
- Basic Softscaping & Turf Re-sets: Typically ranges between $50 to $80 per square metre.
- Comprehensive Architectural Transformations: Incorporating structural retaining, high-end paving, smart irrigation, and custom carpentry generally ranges from $150 to $300+ per square metre, depending entirely on material selections and engineering complexities.

Our design team produces comprehensive 3D spatial layouts, detailed material schedules, and engineering drafts for any required council structural submissions.
3.Earthworks, Drainage, & Sub-Base Preparation
We execute precise site clearing, sub-surface drainage placement, and deep mechanical compaction to create a structurally sound foundation for all future hardscapes.
4.Structural Hardscape Construction
Our skilled tradesmen construct retaining walls, pour liquid limestone, install paving patterns, and build custom timber or composite alfresco structures.
5.Soil Bio-Amendment & Smart Irrigation Installation
We blend organic nutrients and clay conditioners directly into the ground, followed by the installation of automated sub-surface smart irrigation lines.
6.Specimen Planting, Premium Mulching, & Handover
We carefully position your acclimatized plants, lay drought-resilient turf varieties, apply a deep 75mm protective layer of organic mulch, and walk you through your system controls.
Frequently Asked Questions
Do I need council approval for retaining walls or privacy screens?
In most Perth municipalities, structural retaining walls exceeding 500mm in height require formal engineering sign-off and council building approval. Similarly, certain boundary privacy screens and solid structures over a set height require planning consent. As licensed landscape architects, we prepare and lodge all structural drawings and documentation on your behalf to ensure total compliance.
What are the best turf options for Perth’s low-water conditions?
For residential properties across WA, we highly recommend drought-resilient warm-season turf varieties such as Sir Walter DNA Certified Buffalo, Empire Zoysia, or TifTuf Bermuda. These varieties demonstrate superior heat tolerance, rapid self-repair capabilities, and maintain excellent color while utilizing significantly less water than traditional cool-season grasses.
How do you protect plants from the extreme mid-summer heat waves?
Our approach combines deep soil modification with advanced hydro-zoning. By integrating bentonite clay and premium wetting agents, we allow the soil to retain deep moisture. We then group plants with identical water requirements together, apply a thick layer of coarse, chunky mulch to stop evaporation, and program our smart irrigation systems for deep, infrequent watering cycles that encourage deep root growth.
Can you work with existing mature trees on my property?
Absolutely. Preserving healthy, mature trees is a core priority of sustainable landscape architecture. We design custom root-protection zones, utilize porous, non-destructive paving solutions near drip lines, and can even design custom floating timber decks that wrap seamlessly around your existing trees without impacting their health.
