How to Design Concrete Stairs for Split-Level & Modern WA Homes (2026 Guide)
Split-level homes and sloped blocks are common across Perth — from coastal builds to elevated suburban properties. But designing concrete stairs for these homes requires more than just structural strength. The stairs must be safe, durable, compliant and visually integrated into the landscape.
When designed correctly, concrete stairs can become a feature element that enhances street appeal, connects outdoor living areas and complements modern architectural design.
At Woodlands Construct, we specialise in architectural concrete stairs in Perth, built specifically for WA soil conditions and contemporary home styles. This 2026 guide explains how to design concrete stairs that are safe, compliant and built to last.

1. Why Concrete Stairs Suit WA Homes
Concrete is one of the most reliable materials for exterior stairs in Perth because it:
- Handles extreme heat and UV exposure
- Resists movement in sandy soils
- Requires minimal maintenance
- Can be customised for modern architectural designs
- Integrates seamlessly with driveways, pathways and patios
Unlike timber or modular systems, reinforced concrete stairs provide long-term structural stability — especially on sloped blocks.
2. Key Design Considerations for Split-Level Blocks
Designing stairs for modern WA homes requires careful planning.
🔹 Rise & Tread Consistency
Even spacing is critical for safety and compliance.
🔹 Drainage & Water Flow
Stairs must prevent pooling and runoff issues, particularly in winter.
🔹 Soil Preparation
Perth’s sandy soils require proper base compaction and reinforcement.
🔹 Lighting & Visibility
Step edges should remain clearly visible, especially in shaded or landscaped areas.
🔹 Integration with Pathways
Concrete stairs often connect directly to concrete pathways in Perth, ensuring seamless transitions across different levels.
3. Compliance & Safety Standards in WA
Concrete stairs must comply with Australian building standards, including:
- Consistent riser heights
- Adequate tread depth
- Slip-resistant finishes
- Proper edge detailing
Professional installation ensures compliance and reduces long-term risk.
For homes incorporating outdoor kitchens or alfresco areas, stair placement should also align with adjacent

for safe access.
4. Popular Concrete Stair Finishes
🔹 Honed Concrete Stairs
A refined finish ideal for modern homes.
Honed concrete for alfresco areas can be extended to staircases for a cohesive look.
🔹 Exposed Aggregate Stairs
Highly textured and slip-resistant.
Exposed aggregate concrete works particularly well for front entry or garden stairs.
🔹 Architectural Concrete Stairs
Custom formwork, floating steps or integrated seating.
Architectural concrete solutions allow stairs to become statement design features.
Well-designed stairs should feel like part of the overall landscape.
Popular integrations include:
- Matching finishes to concrete driveways in Perth
- Extending pathways through garden beds
- Incorporating built-in seating
- Connecting split-level alfresco areas
- Adding retaining walls in complementary finishes
When stairs are planned alongside landscaping, the result is safer and more visually cohesive.
6. Cost Considerations in Perth (2026)
Concrete stair pricing varies depending on:
- Number of steps
- Site access
- Excavation requirements
- Reinforcement complexity
- Finish type (honed vs exposed)
- Formwork detailing
Architectural staircases with floating or cantilevered designs require specialised labour and higher investment but add strong visual impact.
7. Common Concrete Stair Mistakes
❌ Inconsistent riser heights
❌ Poor drainage planning
❌ No slip-rated finish
❌ Weak base preparation
❌ Mismatch with surrounding concrete finishes
These mistakes compromise both safety and design continuity.
