Outdoor Staircase Types and Materials
Timber Staircase Designs
Timber remains a popular choice for outdoor staircases due to its natural beauty and versatility. We primarily use treated pine and durable hardwoods like merbau, which resist moisture, rot, and insect damage common in WA’s climate. Our timber stairs feature precision joinery and premium finishes for both safety and visual appeal.
We offer fully custom designs, from traditional straight flights to curved, statement staircases with timber stringers and treads. Wood’s warmth and texture create inviting outdoor areas, especially when combined with non-slip coatings for enhanced traction. Our process includes 3D renders to ensure clients visualise the final product before fabrication.
Concrete and Stone Options
Concrete and stone staircases provide robust, low-maintenance alternatives suited to modern or rustic settings. We use high-strength concrete finishes or natural stone like sandstone and granite, which complement Perth’s outdoor environments and handle sun exposure and rain without degradation.
These materials excel in durability and resistance to wear, with minimal upkeep compared to timber. Concrete steps can be customised with textured, coloured, or stamped surfaces to improve grip and aesthetic. Stone stairs add a timeless, solid look while meeting compliance standards for public safety and accessibility.
Handrails and Balustrade Safety Standards
Handrails and balustrades are critical for safety and compliance on outdoor staircases. We manufacture and install handrails from corrosion-resistant metals or hardwoods, designed to meet WA building codes related to height, spacing, and strength. Our solutions also integrate seamlessly with the staircase’s overall design.
Safety features include secure anchoring systems and smooth finishes to prevent splinters or sharp edges. For public or family homes, we adhere strictly to relevant standards, ensuring safe access for children, elderly users, and guests. Balustrades are available in glass, metal, or timber, offering clear sightlines while providing necessary protection.
Outdoor & External Staircase Process and Installation
Architectural Styles and Custom Solutions
We specialise in creating staircases that are true architectural features, not just functional elements. Using timber as a primary material, we offer bespoke designs tailored to each property's style and environment. Our process includes detailed 3D renders, allowing clients to visualise the finished staircase fully before installation.
Handrails are designed to complement both safety and style, using materials that match or contrast the timber structure according to client preference. Our customisation process is straightforward, guiding clients while offering flexibility with finishes, shapes, and materials. This blend of engineering and design creates stairways that elevate outdoor spaces.
Regulations and Durability Considerations
Compliance with Australian building codes, including the NCC and standards such as AS 1657, is strictly enforced in all our projects. We ensure stair dimensions, riser heights, and tread depths meet safety requirements for public and private use. Slip-resistant finishes and proper edge detailing are mandatory to reduce risk in Perth’s variable weather.
Durability is paramount; we select treated timber and corrosion-resistant fixings suitable for external exposure. Installation is managed end-to-end, minimising disruption and maintaining site cleanliness. Our expertise includes managing approvals and inspections, ensuring your staircase not only looks excellent but also lasts and passes all local regulations efficiently.
Outdoor & External Staircase FAQs
Garden steps in standard construction run $480 to $1,400 per step, while entry stairs from street level to elevated front entries range from $850 to $2,400 per step in 2026 across the Perth metro area. For a fully custom outdoor timber or steel staircase, a basic straight flight typically starts from $3,500–$5,500, with hardwood options ranging from $10,000–$18,000 depending on timber species, configuration, and balustrade choice. Costs vary with site access, substrate conditions, and finish requirements, so we provide transparent upfront quotes following an initial on-site assessment.
The right material depends on your home's architectural style, exposure to the elements, and budget. Treated pine and hardwoods like merbau are popular for outdoor timber staircases due to their natural warmth, moisture resistance, and ability to complement Perth's residential aesthetic. Stainless steel is one of the best materials for exterior staircases — it can stand out from the existing home or complement it depending on the overall design, and handles Perth's outdoor conditions with minimal maintenance. Concrete and stone offer the most durability and lowest long-term maintenance, with options including textured finishes, exposed aggregate, and sandstone or granite for a more natural look.
Yes. Slip resistance is a mandatory requirement for all external staircases under the NCC and AS1657. Stairs forming part of access to a habitable building must comply with NCC Volume Two and AS 1657 stair geometry. In practice this means tread surfaces must achieve a minimum P4 or R11 slip resistance rating under AS4586, and edge detailing must be clearly defined to improve visibility in Perth's variable light conditions. We apply non-slip coatings, serrated finishes, or textured surfaces as standard on all outdoor staircase installations.
Outdoor balustrades in Perth face intense WA sun and, for the large share of the population near the coast, salt-laden air that drives corrosion — so the choice of material and grade has to suit those conditions, or a balustrade that looked fine on installation day will deteriorate far sooner than it should. Material options include aluminium ($180–$400 per lineal metre), stainless steel wire ($200–$450 per lineal metre), powder-coated steel ($250–$600 per lineal metre), and glass ($350–$1,100 per lineal metre). For coastal Perth suburbs, Grade 316 marine-grade stainless steel is recommended over Grade 304 for its superior resistance to salt air corrosion.
Whether a permit is required depends on the scope and value of the works. Work valued over $20,000 falls under the Building Services Act 2011 and requires a registered building contractor. Structural changes to external access — including new staircase construction or significant alterations — typically require a building permit from your local council, such as the City of Perth, City of Stirling, or City of Fremantle. We manage all approvals and compliance documentation as part of our end-to-end project management.
Merbau and treated pine are the most widely used timber species for outdoor staircases in Perth, both offering strong resistance to moisture, rot, and the insect damage common in WA's climate. Merbau is particularly well suited to Perth's conditions given its natural oil content and hardness rating, making it durable underfoot and resistant to weathering without requiring heavy maintenance schedules. All outdoor timber components are finished with premium sealants or penetrating oils and can be fitted with non-slip coatings for added safety.
Yes, and achieving a seamless integration between your staircase and the surrounding architecture is central to our design process. We offer fully bespoke configurations — from straight and L-shaped flights to curved feature entries — with material and finish selections tailored to complement your home's existing cladding, decking, paving, or landscaping. Our 3D visual preview process allows you to see the finished staircase in context before fabrication begins, ensuring the result enhances your home's street appeal and overall character.
