How To Build A Temporary Wooden Wheelchair Ramp

Building a temporary wooden wheelchair ramp is a practical, low-cost way to improve home accessibility for a wheelchair, mobility scooter or walking frame. Whether you need a ramp for short-term recovery, an ageing family member, or while you wait for a permanent solution — a properly built wooden ramp can be safe, functional and compliant with Australian standards.

This guide covers everything you need: planning, Australian standards, materials, tools, step-by-step construction and maintenance. If you decide a DIY build isn’t right for your situation, we’ve also included a comparison of ready-made aluminium wheelchair ramps available with NDIS funding.

Before You Build — Key Questions to Answer

• Is this a temporary or permanent solution?
• What mobility aid will use the ramp — wheelchair, scooter, walking frame?
• What is the total rise height from ground to doorway?
• What weight capacity does the ramp need to support?
• Do local council building codes require a permit?
• Is NDIS or Home Care Package funding available for a ready-made ramp instead?

Australian Standards for Wheelchair Ramps

Before building, understand the requirements under AS 1428.1 — the Australian Standard for accessible design. Key requirements for a wheelchair ramp in Australia:

• Maximum slope (gradient): 1:14 for ramps longer than 1,900mm — meaning for every 14cm of horizontal length, the ramp rises 1cm. See our full guide on how to calculate ramp gradient
• Short ramps under 1,900mm: maximum slope of 1:10
• Threshold ramps: must not exceed 280mm in length
• Minimum width: 1,000mm between handrails (typically requires a ramp built at least 1,200mm wide)
• Handrails: required when the ramp rise exceeds 190mm or the ramp length exceeds 1,900mm
• Landings: required at top and bottom, minimum 1,200mm x 1,200mm
• Non-slip surface: mandatory throughout

For a simple step — say 150mm high — the ramp needs to be at least 2,100mm (2.1m) long at a 1:14 gradient. For a standard doorstep of 200mm, you need at least 2,800mm (2.8m) of ramp length.

Quick Ramp Length Calculator

Use this formula: Rise (mm) × 14 = Minimum ramp length (mm)

• 100mm rise → 1,400mm ramp (1:14)
• 150mm rise → 2,100mm ramp (1:14)
• 200mm rise → 2,800mm ramp (1:14)
• 300mm rise → 4,200mm ramp (1:14)

If your rise is 200mm or more, a 2.8m+ wooden ramp is a significant build. Many people find a portable aluminium ramp is easier and cheaper once they calculate the full material cost.

Planning Your Temporary Wooden Wheelchair Ramp

1. Choosing the Right Location

• Consider all entry points — front door, back door, garage access
• Check available space and doorway width (minimum 820mm clear opening required)
• Note existing features — stairs, porches, step edges
• Consider drainage — avoid locations where water pools
• U-shaped or switchback designs work well in smaller spaces where a straight run isn’t possible

2. Calculating Ramp Length and Slope

Measure the total rise from ground level to the floor level inside the doorway. Multiply by 14 to get the minimum ramp length at the Australian Standard 1:14 gradient. Add extra length for top and bottom landings (at least 1,200mm each).

3. Tools Required

• Measuring tape and spirit level
• Circular saw or hand saw
• Drill and bits
• Hammer and mallet
• Framing square
• Pencil and chalk line

4. Materials Required

• Pressure-treated pine — 2×6 or 2×8 for stringers (the sloped side supports)
• 4×4 posts — for support legs and handrail posts
• ¾-inch plywood or composite decking — for the ramp surface
• Galvanised screws and carriage bolts — rust-resistant, essential for outdoor use
• Anti-slip tape or grit strips — applied across the full width every 150–200mm
• Joist hangers — for secure framing connections
• Concrete mix — for setting support posts if required

Step-By-Step Guide To Build A Temporary Wooden Wheelchair Ramp

Step 1: Prepare the Area

Clear and level the ground where the ramp will sit. Remove grass, debris and loose soil. For a more stable base — particularly on soft ground — pour a thin concrete pad at the base where the bottom of the ramp will rest. This prevents the ramp from sinking or shifting over time.

Step 2: Cut the Stringers

Stringers are the sloped side supports that form the skeleton of the ramp. Cut two stringers from 2×8 pressure-treated pine at the correct ramp length and angle. The bottom end should be cut flat (parallel to the ground) for a flush fit. If building over stairs, notch the stringers to sit securely over each step edge.

Step 3: Build the Frame

Position the stringers at the correct width (at least 1,200mm apart for a 1,000mm clear width). Install cross joists between the stringers every 400mm using joist hangers and galvanised screws. Secure the frame firmly to the ground using anchor footings or stakes. Check the frame is level side-to-side using a spirit level before proceeding.

If handrails are required, install 4×4 support posts now — spaced no more than 1,800mm apart and secured with carriage bolts. Posts should extend 900–1,000mm above the finished ramp surface.

Step 4: Install the Ramp Surface

Cut ¾-inch plywood to the full width of the ramp. Lay sheets perpendicular to the stringers and fasten with galvanised screws every 200mm. Ensure all edges are flush and no sheet edges are exposed as trip hazards. For better traction, consider using composite decking boards with built-in texture instead of flat plywood.

Step 5: Install Handrails

If the ramp rise exceeds 190mm or the length exceeds 1,900mm, handrails are required under AS 1428.1. Fix 2×4 timber or metal handrail to the support posts at 865–1,000mm height above the ramp surface. Extend handrails 300mm beyond the top and bottom of the ramp for safe grip during transitions.

Add a kickboard (kerb) along the open edges of the ramp — at least 75mm high — to prevent wheels rolling off the edge.

Step 6: Build Top and Bottom Landings

A landing at the top and bottom of the ramp is required for safe transitions. Minimum size is 1,200mm × 1,200mm. The top landing should be level with the doorway threshold. Build landings from the same materials as the ramp surface for consistency. If the ramp changes direction, a landing at each turning point is also required.

Step 7: Apply Non-Slip Surface

Apply anti-slip grit tape across the full width of the ramp every 150–200mm. This is the single most important safety feature — particularly in wet weather. Alternatively, apply non-slip paint or attach rubber grip strips. Test the surface by walking on it in wet conditions before use.

Step 8: Final Inspection

Before use, check every fastener is tight, all edges are smooth with no splinters, handrails are firmly fixed, the surface is even with no raised edges, and the slope feels safe to navigate with the mobility aid you intend to use.

After Building: Maintenance

• Check all screws and bolts every 3 months — tighten any that have worked loose
• Inspect the surface for rot, splitting or raised edges every 6 months
• Re-apply anti-slip strips annually or when worn
• Apply exterior timber sealant annually to protect against moisture
• Replace any damaged boards immediately — do not use a ramp with structural damage

Should You Build or Buy a Wheelchair Ramp?

A DIY wooden ramp is a practical short-term solution — but it has real limitations compared to a purpose-built aluminium ramp:

• Timber ramps — lower upfront cost, require ongoing maintenance, susceptible to rot and warping, heavier and harder to move, typically not portable
• Aluminium ramps — lightweight, portable, weatherproof, no maintenance required, foldable for transport and storage, immediate availability

For many Australians, a ready-made aluminium ramp is actually cheaper long-term when you factor in the cost of materials, time and ongoing maintenance for a wooden ramp. And if you are an NDIS participant or accessing Support at Home funding, a portable aluminium ramp may be fully or partially funded — making the DIY route unnecessary.

For a permanent ramp installed by professionals and compliant with all Australian standards, see our wheelchair ramp installation service in Sydney and NSW. NDIS home modification funding may also cover a permanent ramp — speak to your OT or visit our NDIS home modifications page.

“We were quoted $800 in materials for a wooden ramp. Our OT recommended a portable aluminium ramp through NDIS instead — it was funded and arrived in two days.” — Support coordinator, Western Sydney NSW

Additional Tips

• One step ramp: for a single step under 100mm, a simple threshold ramp wedge is often sufficient — no construction needed
• Carrying handles: attach handles to the underside of the frame if the ramp needs to be moved regularly
• Ledge transition: attach a small metal transition strip where the ramp meets the landing to ease the transition and prevent wheel catch
• Permit: check with your local council — ramps over 300mm rise or attached to the structure may require a building permit in some Australian states
• NDIS home modification: a permanent ramp may be fundable as a home modification under NDIS or Support at Home — speak to your OT or contact our team for a quote

Frequently Asked Questions

What is the correct wheelchair ramp gradient in Australia?

Under AS 1428.1, the maximum gradient for a wheelchair ramp in Australia is 1:14 for ramps longer than 1,900mm. Shorter ramps can be up to 1:10. See our full guide on how to calculate ramp gradient.

How long does a wheelchair ramp need to be for one step?

Multiply the step height by 14 to get the minimum ramp length at 1:14 gradient. A 150mm step requires at least 2,100mm (2.1m) of ramp. A 200mm step requires at least 2,800mm (2.8m).

What wood is best for a wheelchair ramp?

Pressure-treated pine is the best choice for a wooden wheelchair ramp in Australia — it resists rot, insects and moisture. Use 2×6 or 2×8 for stringers and ¾-inch treated plywood or composite decking for the surface. Always use galvanised or stainless steel screws to prevent rust.

What is a wheelchair ramp material list?

For a standard wooden wheelchair ramp you will need: pressure-treated pine (2×8 for stringers, 4×4 for posts), ¾-inch treated plywood or composite decking for the surface, galvanised screws and carriage bolts, joist hangers, anti-slip grit tape and timber handrail. See the full materials list in the planning section above.

Do I need a permit to build a wheelchair ramp in Australia?

Requirements vary by state and council. Ramps attached to the building structure or over 300mm rise generally require a building permit. Contact your local council before building to confirm requirements in your area.

Can NDIS pay for a wheelchair ramp?

Yes. A permanent wheelchair ramp may be funded as a home modification under NDIS where it is deemed reasonable and necessary. A portable aluminium ramp may be funded under Assistive Technology. Speak with your OT or support coordinator, or contact Gilani Engineering for an NDIS quote.

What is the minimum width for a wheelchair ramp in Australia?

AS 1428.1 requires a minimum clear width of 1,000mm between handrails. This typically means building the ramp at least 1,200mm wide to account for handrail post spacing.

Can Gilani Engineering install a wheelchair ramp for me?

Yes. Gilani Engineering provides professional wheelchair ramp installation in Sydney and NSW for homes and commercial properties. NDIS and Support at Home funding available. Call (02) 8740 8963 to arrange an assessment.

Conclusion

A properly built temporary wooden wheelchair ramp can make a real difference to home accessibility — provided it meets Australian standards for slope, width and safety. Take the time to calculate the correct gradient, use pressure-treated timber and galvanised fixings, and always apply a non-slip surface.

If building a ramp isn’t practical, or if NDIS or Support at Home funding is available, a ready-made aluminium ramp is often the faster, lower-maintenance and more cost-effective solution.
